2 Introduction
MOHID Studio is a graphical user interface for the MOHID Water Modelling System.
With MOHID Studio you can use MOHID Numerical Engines from inside a user
friendly environment, managing all tasks required in order to prepare, execute and
analyze results of numerical simulations done by MOHID Numerical Engines.
2.1 Features
MOHID Studio is an integrated system which permits to manage and edit data files,
create and launch simulations and analyze model results. Map data can be displayed
through an integrated GIS system and time series data can be displayed an integrated
graph visualization engine. A set of tools allows the user to create and preprocess
MOHID data files. A special module allows managing data from field campaigns and/or
automatic stations. MOHID Studio features also offer the possibility to convert data
among a set of common formats and MOHID internal formats. All features of MOHID
Studio are described along this user guide.
2.2 Backward compatibility
With all this features above mentioned MOHID Studio replaces the existing MOHID
graphical user interfaces, namely MOHID GUI, MOHID GIS, MOHID Time Series
Editor and MOHID Post Processor.
Backward compatibility allows importing projects created with MOHID GUI. Some
formats of MOHID ASCII files (points, lines and polygons) has been replaced by a new,
XML based, generic geometry format. Tools to convert from one format to another are
available.
2.3 MOHID in Action
MOHID Studio makes part of the MohidInAction toolkit. MohidInAction, developed and
maintained by Action Modulers, is a set of graphical user interface targeting the
MOHID Water Modelling System, including:
MOHID Studio – Graphical User Interface for MOHID Numerical Engines

2.4 MOHID Studio Editions
After installing MOHID Studio it will work for 30 days for an evaluation period.
Evaluation versions have restricted usage. In order to work with a licensed version of
MOHID Studio, the user needs to register and request a license (for more information
read MOHID Studio – Installation Guide).
There are two types of licensed MOHID Studio versions: MOHID Studio Express and
MOHID Studio Professional. Licenses are distributed on a single machine basis. Action
Modulers may provide other types of licenses upon request.
MOHID Studio Express license is free of charge and it is valid for six month period.
After this period you need buy a MOHID Studio Professional license or renew your
MOHID Studio Express license, if you want to keep using MOHID Studio Express.
MOHID Studio Express works with all features enabled, but with some restriction
(check restrictions on Table 1).
MOHID Professional Edition works without any restriction. License fees vary in
function of the requested license.
Table 1 shows an overview of all MOHID Studio licenses.
On subsection 9.2.2 is explained how to get your license and how to validate it.

2.5 Concepts behind MOHID Studio
MOHID Studio uses a database to store all information about projects and data from
field campaigns and/or automatic stations. Data and result files from numerical models
are stores in a well defined directory structure.
1 During Beta Test license are distributed free of charge. Visit www.actionmodulers.com or contact
sales@actionmodulers.com for updated license fees.

2.6 Starting MOHID Studio
To start MOHID Studio, please select All Programs -> Action Modulers -> MOHID
Studio -> MOHID Studio (see Figure 2-1).
Figure 2-1: Execute MOHID Studio
2.7 Main Window
MOHID Studio’s main window is shown in Figure 2-2. On the top of the main window
the main menu is placed. Inside the client area different dockable windows are located.
The “Explorer” window (currently shown in Figure 2-2) allows managing simulations.
The “Map” window (hidden in Figure 2-2) shows the content of the GIS engine.

Figure 2-2: MOHID Studio’s main window
Beside the “Explorer” window and the “Map” window (that are always open) other
windows may appear in the client area of the main window (for example: XY Graphs,
Tools, Reports, etc.).
2.7.1 Dockable Windows
Windows inside the client area are “dockable”. This means that the user can arrange
them as needed. Figure 2-3 shows MOHID Studio’s main window where the “Explorer”
window and the “Map” window are docked side by side.

To change the dock state of a window, double click on the title bar (this turns the
window floating). Then drag it to the desired position.
2.7.2 Main Menu
The main menu is divided into 9 different tabs and works in a similar way as the menu
of Microsoft Office 2007. Each tab contains a ribbon menu, organized in groups, with
several items for a specific task. As example Figure 2-4 shows the ribbon menu related
to the Map window. Each menu is explained in detail in this guide.
Figure 2-4: Example of a Ribbon Menu (Map)
2.8 Home menu
The Home ribbon menu (see Figure 2-5) is the first menu displayed by MOHID Studio
and helps you to getting started with the application. This menu is divided in three
distinct groups: Workspace, Getting Started with MOHID and Links. The workspace
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 8
group allows to use workspaces very quick (learn how to use workspaces in subsection
2.10).
Figure 2-5: Home menu
The group “Getting Started with MOHID” has some examples to introduce you to
MOHID Studio application. These examples allow importing sample solutions and
sample unit tests for a better understanding of MOHID Studio. These samples contain
basic examples helping you to create your own solutions and projects (for more
information read subsection 2.9).
The Links group contains a variety of links where it is possible to find some help with
the MOHID community.
2.9 Getting Started with MOHID Studio
The best way to getting start working with MOHID Studio is to load a sample solution.
On the group “Getting Started with MOHID”, from menu Home (see Figure 2-5), there
are two sample solutions (one MOHID Water [blue] and other of MOHID Land
[yellow]) and two samples of unit tests (one of MOHID Water and one of MOHID
Land). MOHID Studio solutions are always represented by a color corresponding to the
type of model for an easy way to work. The color blues stand for MOHID Water
solutions, the color yellow stands for MOHID land solutions and the color red stands for
MOHID River solutions.
The sample solution is loaded to MOHID Studio by pressing one of the sample
solutions button and everything is ready to run, letting you easily explore all the features
of MOHID Studio. The sample solution loaded can be changed or modified according
with your needs. It also can be saved, replacing the original sample solution. So, the
next time the sample solution button is pressed on “Getting Started with MOHID” from
menu Home (see Figure 2-5), the sample solution saved will be prompted with all the
opened layers. Although the original sample solution was replaced, it is always possible
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 9
to restore it again. The original sample solution can be restore executing simple three
steps:
1 – Delete the workspace associated to the sample solution on Workspace
Manager (on the group “Workspace”, from menu Home (see Figure 2-5));
2 – Delete the sample solution saved on Solution Manager (on the group
“Solution”, from menu Project (see Figure 3-1) – for more information read section
3.1.3 );
3 – Delete the projects from the sample solution on Project Manager (on the
group “Domain”, from menu Project (see Figure 3-1) – for more information read
section 3.2.4).
MOHID Studio help can always be found in this user guide, in MOHID Studio tutorials,
on internet forums or by e-mail. It is possible to export your solution and then request
for Professional Help (to see how to export solution check subsection 3.1.4) through the
option “Request Support”.
2.10 Workspaces
2.10.1 Introduction to Workspaces
Workspaces allow storing the state of MOHID Studio between two consecutive work
sessions. For this the workspace keeps track of the current open solution (see section
3.1) and loaded layers (see section 4).
2.10.2 Working with Workspaces
MOHID Studio does not have an explicit way to create a workspace. After MOHID
Studio finished starting, it immediately asks for the workspace to use. You might select
an empty workspace or load an existing one, as shown in Figure 2-6.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0
Figure 2-6: Create a new workspace or load an existing one
When MOHID Studio exits it will always ask if the user wants to save the current
workspace, as shown in Figure 2-7.
Figure 2-7: Save workspace on program exit
Workspaces can be changed or saved at any time during a session. To open a workspace
(or create a new one) press Open in “Workspace” group from menu Home (see Figure
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 1
2-5Figure 2-5), to save the current workspace press button Save in “Workspace from the
Home menu (see Figure 2-5).
2.10.3 Managing Workspaces
Managing workspaces involves renaming and deleting existing workspaces. This can be
done by selecting Workspace -> Manage from the menu “Home” (see Figure 2-5). The
workspace manager will appear (like the one on Figure 2-8) and the user can easily
manage your MOHID Studio Workspaces.
Figure 2-8: Managing Workspaces
There are only two restrictions when managing Workspaces:
Names of workspaces must be unique;
The workspace currently opened cannot be removed.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 2
3 Project Management
MOHID Studio organizes projects by dividing them into three major units: (i) solutions,
(ii) domains and (iii) simulations.2
A solution is the topmost unit and groups together one or more domains. For each
workspace, only one solution can be opened by MOHID Studio.
A domain is characterized by a geographic region which is covered (through the Digital
Terrain Model), the type of numerical model to use (MOHID Water, MOHID Land or
MOHID River) and the physical path on the disk where files are stored. Each domain
belongs to one or more solutions and contains a set of simulations. In the case of
MOHID Water, nested domains can be created.
A simulation is one execution of the numerical model over a given period of time. All
files (input files and result files) related with the execution also belong to the
simulation.
Projects can be managed from the “Project” menu (see Figure 3-1).
Figure 3-1: Project menu
Data associated with projects is displayed in the “Explorer” window (see Figure 3-2).
This window is divided into three main areas: (i) the Project Tree on the left, (ii) the
Modules window in the middle and (iii) the File Editor on the right.
2 MOHID GUI had a similar structure. The correspondence from MOHID GUI to MOHID Studio is:
Solution = Project; Simulation = Domain and Run = Simulation
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3
Figure 3-2: Explorer window
The Project Tree shows the hierarchical structure of projects. In Figure 3-2 a solution
called “OpenMI Implementation” is shown. This solution contains two domains: (i)
Sample Estuary and (ii) Sample Catchment. The domain Sample Estuary shows two
simulations, ReferenceRun and Sim#2.
Some functions which can be accessed from the “Project” menu can also be accessed
from the context menu (by clicking on the right mouse button) accessible from the
Project Tree (see Figure 3-3).

Figure 3-3: Accessing project management options from the context menu
3.1 Solution
3.1.1 Creating or opening solutions
A new solution can be created by selecting Solution -> New from the “Project” menu
(see Figure 3-1) and an existing solution can be opened by selecting Solution -> Open.
A window like shown in Figure 3-4 will be shown.
When creating a new solution, a name of the solution must be provided.
Figure 3-4: Creating a new solution
When a new solution is created or opened, the current solution opened in MOHID
Studio will be closed. Note that the solution of the current workspace will be replaced
by the new solution opened or created. To prevent unwanted results, save the workspace
before open or create the new solution.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 5
3.1.2 Closing solutions
Solutions can be closed by selected Solution -> Close from the “Project” menu (see
Figure 3-1).
3.1.3 Managing solutions
There are several tasks which can be performed with solutions: (i) rename, (ii) delete,
(iii) import and (iv) export. All these tasks can be performed by selecting Solution –>
Manage from the “Project” menu (see Figure 3-1).
Figure 3-5: Managing solutions
To change the name of a solution, use the “Rename” button. Any new name can be
given, with the exception that solution names must be unique.
To remove a solution, use the “Remove” button. Any solution can be removed, except
the currently opened solution. When a solution is removed, domains associated to the
solution are NOT removed. All domains remain available in the Domain Manage (for
more information read subsection 3.2.4).
3.1.4 Exporting solutions
Exporting a solution allows to store all information about the solution, including all
domains and data files, in a single ZIP file. This is useful if you want to exchange
solutions between computers or if you want to request professional help. To export a
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 6
solution, select the “Export” button from the “Managing Solution” window (see Figure
3-6). A window like the one shown in Figure 3-6 will appear.
Figure 3-6: Exporting solutions
The file name must be the “ZIP” archive to which the solution is exported. By default,
the exported ZIP archive does not include the result files (since they can be very large).
Result files are only included if the “Include Result files” options is checked. By
clicking the “Export” button the export process begins. Depending on the number and
size of files included in the solution, the process can take more or less time.
3.1.5 Importing solution
To import a solution select the “Import” button from the “Managing Solution” window
(see Figure 3-6). A window like shown in Figure 3-7 appears.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 7
Figure 3-7: Importing solutions
Importing solutions allows processing two types of solutions: (i) a previously exported
solution or (ii) a project from MOHID GUI.
To import a previously exported solution check the MOHID Studio option and browse
for the ZIP archive which contains the solution.
To import a MOHID GUI project check the MOHID GUI option and browse for the
MOH file of the MOHID Project.
By clicking the “Import” button the import process begins. Depending on the number
and size of files included in the solution, the process can take more or less time.
NOTE: If a solution with the same name of the solution to import already exists, the
newly imported solution is automatically renamed.
3.2 Domains
Like mentioned previously domains are characterized by a geographic region which is
covered (through the Digital Terrain Model), the type of numerical model to use
(MOHID Water, MOHID Land or MOHID River) and the physical path on the disk
where files will be stored. Each domain belongs to one or more solutions and contains a
set of simulations. In the case of MOHID Water, nested domains can be created.
3.2.1 Creating domains
New domains can be created by selecting Domain -> New from the “Project” menu
menu (see Figure 3-1). A window like shown in Figure 3-8 appears.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 8
Figure 3-8: Creating a new domain
The information provided in the “Creating a new domain” window characterizes your
domain. The following restrictions must be fulfilled:
the domain name must be unique;
the root directory must be empty (when the domain is created or imported).
The path to the Digital Terrain Model may not be specified during domain creation (if,
for instance it hasn’t been created yet or you want to import to the \General Data\Digital
Terrain folder after the project has been created ISTO TEM SER EXPLICADO
ALGURES). It is always possible to come back to the window shown in Figure 3-8 by
accessing the domain properties.
During domain creation, MOHID Studio creates four special folders to store general
data files: (i) one root directory (General Data) and (ii) three subdirectories (Initial
Conditions, Boundary Conditions and Digital Terrain). It also creates three folders
specific for MOHID model runs: (i) data, (ii) exe and (iii) res. The directory structure
for one specific folder, after domain creation, is shown in Figure 3-9.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 9
Figure 3-9: Directory structure for a domain
NOTE: This approach is different the one used by MOHID GUI, since there is now one
General Data folder for each domain (in MOHID GUI the General Data Folder was
shared among projects).
3.2.2 Domain properties
Domain properties can be accessed and changed by selecting Domain -> Properties
(ISTO IST AINDA NÃO ESTÁ FEITO NO CÓDIGO ) from the “Project” menu (see
Figure 3-1). The same window as shown in Figure 3-8 will appear.
NOTE: It’s not recommended to change the Root Directory of a domain after data files
and/or simulations have been added to the domain.
3.2.3 Removing domains
Domains can be removed by selecting Domain -> Remove from the “Project” menu (see
Figure 3-1). After removing a domain from a solution it continues to exit in the data
base. To delete permanently a domain use the Manage Domains options (see subsection
3.2.4).
3.2.4 Managing domains
Domains can be “managed” by selecting Domain -> Manage from the “Project” menu
(see Figure 3-1). A window like shown in Figure 3-10 will appear.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 0
Figure 3-10: Managing Domain
Using this window is possible to create new domains, by selecting the “Add” button to
edit existing domains by selecting the “Edit” button and remove a domain by selecting
the “Remove” button. After removing a domain, MOHID Studio asks if the folders
associated to the domain are also to be removed (Figure 3-11).
By selecting “Yes” the entire directory will be permanently deleted from your hard
disk, including the structure of the domain’s Root Directory and including all files
inside that directory. Before press “Yes”, make sure that you do not have important files
inside that directory or subdirectory.
Figure 3-11: Remove Domain
3.2.5 Nested domains
Nested domains are used to run models with sub models. This feature is currently only
implemented in MOHID Water, so MOHID Studio only allows creating nested domains
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 1
for domains of the type “MOHID Water”. The process of creating nested domains is the
same as for root domains, with the exception that the “father” domain must be selected
in the tree view while you the new, nested, domain is created. When creating a nested
domain, MOHID Studio set the root directory for the nested domain automatically.
Figure 3-12 shows the Project Tree with an example of a nested domain (domain North
Atlantic and with the nested domain Portuguese Coast).
Figure 3-12: Project Tree showing a domain with a nested domain
3.3 Simulations
3.3.1 Creating simulations
To create a new simulation, the tree node where the simulation is to inserted must be
selected first. This node can either be a domain node or a simulation node, depending of
the option if the user wants to insert a first simulation into a domain or temporal
sequence of a previous existing simulation. After selecting the desired node, a new
simulation can be inserted by selecting Simulation -> New from the “Project” menu.
A window like shown in Figure 3-13 will appear. This window can be used to specify
the properties of the simulation: (i) name, (ii) description and (iii) modules to activate.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 2
Figure 3-13: Creating a new simulation
Each simulation receives automatically an ID (internal identification and cannot be
changed). All files which belong to a given simulation will contain this ID at the end,
before the extension of the file. For example, the input file for the hydrodynamic
module of the simulation with ID 5 will be called “Hydrodynamic_5.dat”.
3.3.2 Simulation properties
Simulation properties can be accessed and changed by selecting Simulation ->
Properties from the “Project” menu (see Figure 3-1). The same window as shown in
Figure 3-13 will appear.
3.3.3 Root and sequential simulation
MOHID Studio distinguishes between two types of simulations: (i) sequential
simulations or (ii) root simulations.
MOHID Studio assumes that root simulations always start as “cold start” (initial
conditions are obtained from the data files) and that sequential simulations always start
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 3
as “hot start” (initial condition are obtained from the previous run). MOHID Studio
allows creating branches of simulations order to study different scenarios.
Figure 3-14 shows an example of the Project Tree after setting up the simulations for
scenarios which involve studying the combination of the following cases: (i) No
Discharge vs. With Discharge and (ii) East Wind vs. West Wind. This example shows
two root (Spin up) simulations, one for the “No Discharge” case and one for the “With
Discharge” case. For both root simulations several in time sequential simulations are
shown (Day 1 and Day 2). Branches are created (starting after the Spin Up) for the
“East Wind” and “West Wind” cases.
Figure 3-14: Project Tree showing root and sequential simulation and the usage of branches
In case of inserting a simulation which continues from a previous simulation MOHID
Studio will automatically set the start date of the newly inserted simulation to the end
date of the previous simulation and change the continues compute option in all module
data files to true.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 4
3.3.4 Removing simulations
Simulations can be removed by selecting Simulation -> Delete from the “Project” menu
(see Figure 3-1). By doing so, the current selected simulation and all nested child
simulation will be removed.
3.3.5 Files associated to simulation
Numerical models like MOHID need data files (to read initial conditions and general
compute options) and produce result files. Each simulation has associated a set of files.
After selecting a specific simulation in the Project Tree, files associated to the selected
simulation are displayed in the Module List Views, located in the middle of the
Explorer Window. Figure 3-15 shows files associated to the selected simulation in the
Module List Views. On top are located Data Files, in the middle HDF Files and at the
bottom Time Series Files.
Figure 3-15: Files associated to simulations
Data files can be easily modified and saved by MOHID Studio (for more information
about this method read subsection 3.5).
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 5
3.3.6 Copying simulation data files
It is common for users to set up two simulations which are very similar. In this case it
can be useful to copy data files from one simulation to another. The best way to it is
following the next instructions:
Select the source simulation in the Project Tree;
Select the files to copy from the “Data Files List View”;
Press the button Simulation -> Copy from the “Project” menu;
Select the target simulation in the Project Tree;
Press the button Simulation -> Paste from the “Project” menu.
3.3.7 Cleaning simulation result files
In some circumstances it might be useful to erase all result files associated with a
specific simulation. This can be done selecting the simulation in the Project Tree and
then press the Simulation -> Clean button from the “Project” menu.
3.4 Organizing data files
Data files play a central role when running numerical simulations. Like described
previously, MOHID Studio:
creates and organizes automatically data files associated to simulations;
creates a directory structure where data files associated to domains can be
stored.
3.4.1 Data files associated to simulations
When a simulation is selected in the Project Tree, in the Module List Views the files
associated to the selected modules are displayed. Names of these files are automatically
created based on the simulation ID.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 2 6
3.4.2 Data files associated to domains
Data files associated to domains (e.g. Digital Terrain, Boundary Conditions and Initial
Conditions) must be supplied by the user. These files should be stored in the General
Data directory (or any subdirectory). The directory structure of the General Data
directory is displayed in the Project Tree. When a directory is selected in the Project
Tree, the files located in this directory are displayed in the Module List Views.
NOTE: MOHID Studio considers the HDF Files has an extension *.hdf or *.hdf5 and
Time Series Files has the extension *.sr*.
From the context menu (right mouse button) of the Project Tree several tasks can be
performed:
Creating a new directory inside the General Data directory
Removing an existing directory
Create a new empty data file
Create a new time series template file
Import an existing file
Figure 3-16: Project Tree context menu to perform tasks related with the general data directory

3.5 Editing data files
Data files are edited in the File Editor, which is located at the right side of the Explorer
window (see Figure 3-17). To edit a data files, simply double click over them inside the
Data File List View. Data files will appear as tabs inside the File Editor.
Figure 3-17: File Editor with two open data files
If a data files for a given module doesn’t exist yet, MOHID Studio will create it
automatically, using a template with the most common options for the selected module.
Inside the File Editor data files have syntax highlighting based in the following rules:
Keyword are red
Keyword values are blue
Block delimiter are purple
Comment lines are green
(MOHID DATA FILES – AN OVERVIEW – reference from HERE???)
In the upper right corner of the File Editor are available a set of commands which help
to edit data files:
Find Text / Replace Text – to find / replace a specific text inside the data file
Comment / Uncomment lines

3.6 Executing Models
When all data files are prepared it is possible to execute simulations. MOHID Studio
provides two options to execute modules: (i) run a single simulation or (ii) schedule a
set of simulations.
3.6.1 Executing a single simulation
To execute a single simulation, just select the simulation to execute from the Project
Tree and hit the Execute Models -> Run Simulation from the “Project” menu (see
Figure 3-1). The simulation starts immediately.
3.6.2 Executing a set of simulations
A set of simulations (including nested simulations) can be executed by selecting
Execute Models -> Schedule Simulations from the “Project” menu. A window like
shown in Figure 3-18 will appear.

Figure 3-19: Scheduling nested domains
3.6.3 Simulation progress
Feedback about simulation progress appears below the Project Tree, in the “Model
Controller” window (Figure 3-20). The progress bar indicates the evolution of the
simulation.
Figure 3-20: Model Controller Window
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 3 1
It is possible to see the screen output from the numerical model by selecting the
“Output” button in the model controller. A window like shown in Figure 3-21 appears.
Figure 3-21: Model screen output window
The execution of the model can be interrupted by selected “Kill” from the model
controller.
When a simulation is finished, all screen output from the model is stored. It is possible
to access this information by selecting “View Last Log” from the context menu of the
Project Tree.
3.7 Visualizing results
After model execution, the list views containing HDF results and Time Series results are
updated. There are several options to visualize the results directly inside MOHID
Studio. All options can be accessed from the commands located in the upper right
corner of the list views.

3.7.1 Visualizing HDF results
HDF Files can be loaded into the GIS map engine as animated maps. There several
options to display HDF results, depending on the module. A detailed description on how
to display animated maps inside MOHID Studios can be found at section 4.
From the HDF List view it is possible to load HDF files as polygons, vectors or
lagrangian animations, using the command in the upper right corner of the list view.
Figure 3-22: HDF List View with commands
3.7.2 Visualizing Time Series results
Time Series Files can be loaded into the XY Graph engine. A detailed description on
how to display XY Graphs inside MOHID Studio can be found at section 5.
From the Time Series List view it’s possible to load Time Series files into the XY
Graph engine or edit them in the File Editor.

4 Map Visualization (GIS)
4.1 Introduction
MOHID Studio uses a customized Geographical Information System (GIS) to display
dynamic maps. Information which can be displayed includes raster images and vector
data. All data is presented in form of layers.
Raster images are typically used to add a background to the image and can be added
from local images and from Web Map Servers (WMS).
MOHID Studio supports different kinds of Vector data sources. Special emphasis is
given to data related to MOHID models: (i) special ASCII (and XML) files in MOHID
format and (ii) model results stored in HDF Files. Other vector data sources can also be
added, including ESRI Shapefiles and HGT files. Vector data can be displayed in
several different ways, using simple styles or theme based styles. MOHID Studio also
supports time animated vector data.
Tasks related to the map visualization can be performed from the “Map” menu (see
Figure 4-1).
Figure 4-1: Map menu
Layers are displayed in the “Map” window (see Figure 3-2). This window is divided
into two main areas: (i) the Layers List on the left and (ii) the Map Display on the right
(see Figure 3-2).
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 3 4
Figure 4-2: Map window
The Layers List shows the currently loaded layers of the map. At the bottom of the
Layers List is located a small tool box which allows to control the current display time
(in the case time animations are loaded). The Date & Time control is detailed explained
on subsection 4.2.
The Map Display shows the maps based on the currently loaded layers. A small set of
tools, located in the upper right corner of the Map Display, allows panning, zooming
and querying the map. At the right side of the Map Display appears the legend of the
currently loaded layers.
Some functions which can be accessed from the “Map” menu can also be accessed from

4.3 Layers General Properties
Layers loaded into MOHID Studio’s GIS have common properties: (i) if they are to be
displayed (enabled/disabled), (ii) minimum/maximum zoom visible, and (iii) layer
name.
Enabled layers are displayed in the map on top of each other, considering the same
order as shown in the Layers Lists (The top layer in the Layers List is the topmost layer
in the Map Display). Layers can be moved up and down through the context menu or
through the buttons “Move up” or “Move Down” in group “Manage Layers” from Map
menu (see Figure 4-1). Layers can be enabled / disabled by checking / unchecking the
box in the “Visible” column in the Layers List.
Properties of a layer can be accessed by: (i) double clicking over it on the Layers List,
(ii) selecting “Properties” from context menu of the Layers List or (iii) by pressing F4.

4.4 Raster Layers
Raster layers are used to mainly to display some background in the map. MOHID
Studio supports two main types of raster layers: (i) raster collections from georeferenced
images and (ii) raster images from WMS server.
To use the Raster Layers features is necessary to have FW Tools 2.4.2 installed and
correctly configured in MOHID Studio. For more information check the MOHID Studio
– Installation Guide.
4.4.1 Raster Collections
Raster Collection are a set of georeferenced raster images which are stored on your
computer. These images can be added by selecting Background -> Raster from the Map
menu (see Figure 4-1). A window like shown in Figure 4-6 will appear to configure the
Raster Collection. Here it is possible to add or remove individual images to the raster
collection.
Figure 4-6: Adding Raster Collections
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 3 8
Individual raster images must be georeferenced. This means that these images are either
images which contain information about there georeference (e.g. GeoTiff) or that there
is an additional file which contains this information (ESRI world file - *.jpw).
For large raster collections, and for raster collection with different resolutions, the
option to set the minimum and maximum zoom level is particularly useful. This allows
MOHID Studio to show always in image with the appropriate resolution, without being
very memory demanding.
For example, if the Blue Marble collection3 is to be used as background image, Table 2
shows a typical configuration for minimum and maximum zoom levels.
Resolution Minimum Zoom Maximum Zoom
250m 0.0 1.0
1km 1.0 10.0
4km 10.0 30.0
16km 30.0 Infinite

4.4.2 WMS Layers
WMS layers are provided by online servers over the Internet. MOHID Studio has two
preconfigured WMS Servers: (i) Demis Map and (ii) JPL Nasa. WMS Layers can be
added by selecting Background -> WMS from the Map menu. A window like shown in
Figure 4-8 will appear. In the window it is possible to select from one of the predefined
WMS Servers or to add the name address (URL) to a user defined WMS Server. After
selecting the server, the “Get Layers” button must be pressed, in order to obtain the list
of possible WMS layers.
NOTE: There are several different WMS versions. MOHID Studio only supports WMS
versions 1.0.0, 1.1.0, 1.1.1 and 1.3.0.

4.5 MOHID ASCII Layers
MOHID ASCII layers are special layers to load files which contain simplified
information about geometries specific to the usage of MOHID Water Modelling
System. These layers include: (i) XYZ Points, (ii) Grids, (iii) Grid Data, (iv) Drainage
Network and (v) Polygons.
For example, Grid Data files are used by MOHID Water to read information about the
bathymetry.
Some tools included into MOHID Studio use information from this layer while other
tools help to create specific MOHID ASCII Files. For example, to create a bathymetry
(Grid Data File) it is necessary to load:
the base data in form of a XYZ Points layer;
information about the grid in form of a Grid Layer;
information about non compute areas in form of a polygon file.

4.5.1 XYZ Points layer
XYZ Point layers are loaded from XYZ Files (see XYZ Files) and are used as input to
create Grid Data Files. A XYZ Point layer can be added by selecting ASCII -> XYZ
Points from the “Map” menu (see Figure 4-1).
After selecting a valid XYZ file, a window like shown in Figure 4-10 appears. By
default the layer name is based on the filename, the minimum and maximum visibility
are set to “always” visible and the layer style to the default gradient style, respecting the
minimum and maximum values found in the XYZ file.

4.6 HDF Files
MOHID uses HDF files to store information about large data sets. Within MOHID,
HDF files are primarily used to store model results, but they may also be used to
provide boundary conditions or initial conditions.
MOHID uses HDF files with some special groups / datasets, in order to store time based
and georeferenced data sets. Dataset can apply to grid based (sometimes referenced as
polygon based) datasets, vector field datasets, drainage network data sets and lagrangian
particle data sets.
4.6.1 Grid Map
HDF Grid Map layers are the most common HDF layers used in MOHID (Studio). A
HDF Grid Map layers allows to display the temporally evolution of a grid based
property based on the information stored in a single HDF file. A HDF Grid Map layer
can be added by selecting HDF -> Grid Map from the “Map” menu (see Figure 4-1).
After selecting a valid HDF file, a window like shown in Figure 4-16 will appear.
Figure 4-16: Adding a Grid Map vector layer
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 4 8
This window has several options related to select which and how the data is presented:
from the Feature drop down box it’s possible to select the property to represent;
from the Mapping drop down box the type of mapping (Water points or Open
points)
from “Geo Dataset” if metric (Connection X / Connection Y) or geographic
coordinates (Latitude / Longitude) are to be used
from Slice the horizontal layer (by default this property is set to the top most
layer
Other options shown in Figure 4-16 have been explained earlier in the document.
After adding a HDF Grid Map layer the time animator below the layers window gets
enabled. Using this animator it is possible to loop trough individual layers of the HDF
Grid Map.
4.6.2 Vector (Arrow) Map
HDF Vector Field layers are used in MOHID Studio to display the temporally evolution
of a vector field based on the information stored in a single HDF file. A HDF Vector
Field layer can be added by selecting HDF -> Vector Field from the “Map” menu. The
window which appear is the same as the one shown in Figure 4-16 with the only
difference that the available features which appear are vector fields (with X and Y
components). Figure 4-17 shows a Vector Map of the velocity at the Tagus Estuary
Mouth.

single HDF file. A HDF Drainage Network layer can be added by selecting HDF ->
Drainage Network from the “Map” menu. The window shown in Figure 4-16 appears.
4.6.4 Lagrangian Particle Map
HDF Lagrangian Particle layers are used in MOHID Studio to display the temporally
evolution of properties of lagrangian particle based on the information stored in a single
HDF file. A HDF Lagrangian Particle layer can be added by selecting HDF -> Particle
Field from the “Map” menu. The window shown in Figure 4-16 appears.
4.7 Other Vector Layers
Besides the MOHID specific vector data formats listed previously (MOHID ASCII
Layers and HDF Files), other vector layers can be loaded into MOHID Studio’s GIS
engine. Providers of these layers are: (i) ESRI Shapefiles, (ii) XML Geometries and (iii)
HGT Layers.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 5 0
4.7.1 ESRI Shapefiles Layers
ESRI Shapefiles are widely used to store geographic data. Layers based on data from
ESRI Shapefiles can be added by selecting Vector Data -> Shapefile from the “Map”
menu (see Figure 4-1). A window like shown in Figure 4-10 appears.
4.7.2 XML Geometry Layers
XML Geometries are layers based on XML files which contain geometries stored by
MOHID Studio (see subsection 10.3). Layers based on XML Geometry files can be
added by selecting Vector Data -> XML Geometry from the “Map” menu. A window
like shown in Figure 4-10 appears.
4.7.3 HGT Layers
HGT layers are based on NASA SRTM (Shuttle Radar Topography Mission) files and
are the main source for building digital terrains for MOHID Land. HGT Layers can be
added by selecting Vector Data -> Nasa HGT from the “Map” menu. A window like
show in Figure 4-18 appears.
Figure 4-18: Adding a HGT vector layer

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 5 1
In this window (see Figure 4-18) it is necessary to specify the geographic region for
which the HGT layer is to be loaded: (i) the current view or (ii) the boundaries of a
given layer.
After selecting the region, the necessary HGT files are directly downloaded from
NASA’s FTP server and cached on your local computer.
NOTE: Downloading and displaying HGT layers for big areas can be time consuming
and generate a lot of internet traffic. It is recommended that you should not try to load
HGT layers that cover more than 4 square degrees once.
4.8 Monitoring Station Layers
Location of the monitoring stations stored in MOHID Studio’s database can be
displayed on the map by selecting Monitoring Stations -> Meteorological, Hydrological
or Water Quality from the “Map” menu.
4.9 Label Layers
Label layers are a special kind of layers which allows to obtain quickly information
about the numerical data which is represented by a given vector layer. Label layers can
be created be choosing “Create Label Layer” from the context menu in the label list.
Figure 4-19 shows an example of a label layer created from a vector layer.

4.10 Moving Layers
Layers are displayed in the map on top of each other, considering the same order as
shown in the Layers Lists (The top most layer in the Layers List is the topmost layer in
the Map Display). Layers can be moved up and down through the context menu of the
Layers List or by selecting Manage Layers -> Move Up / Down from the “Map” menu.
Layers can be removed from the map selecting Manage Layers -> Remove from the
“Map” menu.
4.11 Layer Styles
Vector layers are rendered based on their current layer style. Layer styles can be
“simple” or based on the feature data which is represented. Different layer styles can be
applied to different vector layers, depending on the type of the style and type of the
layer.
Layer styles of a given layer can be accessed by selecting “Edit” in the layers properties
window. Figure 4-20 shows an example of how to access the layer style.

5 Graph Visualization
5.1 Introduction
MOHID Studio uses a customized graph engine to display time series in from of XY
Graphs. The series can be loaded directly from MOHID ASCII Time Series files or
from MOHID Studio’s database.
Tasks related with Graph Visualization can be performed from the “XY Graph” menu
(Figure 5-1).
Figure 5-1: XY Graph menu
Time Series are displayed in “XY Graph” windows (Figure 5-2). “XY Graph” window
is divided in two main areas: (i) the Series List on the left side and (ii) the Series
Display on the right side.
Figure 5-2: XY Graph window
The Series List shows the currently loaded series and the Graph Display the series
graph. A small set of tools, located in the upper right corner of the Graph Display,
allows zooming and querying the series graph.

6 Time Series Manager
6.1 Introduction
MOHID Studio contains a set of utilities that allow creating, managing and analyzing
Time Series. All utilities related with Time Series (Monitoring Stations, Parameters,
etc.) are in the Environmental Monitoring menu (see Figure 6-1) and in the Reports
menu (see Figure 6-2).
Figure 6-1: Environmental Monitoring menu

6.2 Environmental Monitoring menu
All Time Series are composed by a Parameter, Monitoring Station, date and a list of
values measured or modeled.
Missing more description!?…
6.2.1 Parameters
The Parameter Manager (Figure 6-3) displays the list of all existent parameters. In this
window is possible to create new parameters, edit or remove existent parameters. The
parameters that are associated to existent Time Series cannot be removed. To remove
them, the Time Series must be removed first.

The Parameters properties window (Figure 6-4) allows create new parameters or editing
existent parameters. The property “Name” is the complete name of the parameter and
the “Display name” is the name that will be displayed in all the menus or reports. The
“Display name” field cannot be empty. This is the name that will be always displayed in
Time Series, all windows and Reports. The property “Units” refers to the units of
parameter, and it can be blank and the numeric format of parameter value can be
changed in the property “Display numeric format”.

The Time Series properties are: Parameter (to add new parameters check the section
6.2.1), Monitoring Station (to add new monitoring stations check the section 6.2.2) and
monitoring location (ticket the check box to use the same location as the monitoring
station), Modeled Domain and Time Series Type (surface, middle, bottom, composed,
not defined or unknown).
The Time Series Values are the values that are obtained (by a measured or a modeled
result) for a specific instance of time. These values can be created, modified, removed
or imported (for more information, see section 6.2.4). To edit any value from the time
series value list (date or value) double click on the value to edit.

6.2.4 Importing and Exporting Time Series
The Import Time Series Files windows (see Figure 6-9) allow to importing MOHID
ASCII Time Series Files (more information about this file type on the subsection 10.2)
to MOHID Studio.
The easiest way to import one time series file to MOHID Studio is to following the next
steps:
1) Choose one MOHID ASCII Time Series Files through the browse button;
2) Select the time series from file to import (if the file only has one time series, it
will appear one Time Series);
3) Choose to add to an existent Station / Time Series or Create a new station;
4) Click “import”.
To import one or more time series from the same file:
5) Choose the time series;
6) Choose the monitoring station (if a new one was created);
7) Click “import”.

6.2.5 Moving Time Series
Moving Time Series are Time Series that the geographic measured point may change
along the time in any direction (Latitude, Longitude and/or Depth). Each measure refers
to a specific monitoring station, although the geographic coordinates may vary.
The Moving Time Series windows (see Figure 6-11) display the list of all moving times
series that are included in MOHID Studio database. Is possible to create, edit or delete
moving time series in this window.
Figure 6-11: Moving Time Series window

The Moving Time Series properties window (see Figure 6-12) display all the
information about a determine Moving Time Series. All the information may be added
or changed in this window, just like in Time Series properties window (see Figure 6-8).
In this window is also possible to add a description about the moving time series (for
example: “Demo Moving Time Series”). It is also possible to add a short description to
the values (for example: “estimated value”, “average value”, “Error – no value”)
helping to understand the values latter, if anything goes wrong. To edit the values
double click on the value to edit.
Figure 6-12: Moving Time Series properties window
Instead of filling the Moving Time Series properties window, is possible to import a
batch of moving time series values, through an XLS File (for more information, please
read section 6.2.7).
6.2.6 Field Campaigns and Visited Points
All the data and files from the field campaigns (photos, sheets, etc.) can be organized
and stored on a special feature from MOHID Studio. The Field Campaign manager
window (see Figure 6-13) allows add, edit or remove field campaigns.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 8 0
Figure 6-13: Field Campaign manager window
The Field Campaign properties window (see Figure 6-14) displays all information about
one Field Campaign. The properties of a Field Campaign are the name, the dates where
the campaign took place and some description about the campaign. It is possible to
attach any type of file to this field campaign (for example: authorization sheets, the field
campaigns schedule, itinerary, etc.). All the files attached can be viewed (opened by the
system default application) or removed. The files are attached to the MOHID Studio
database, so the path to file can be modified or the file can be removed from disk.
The Field Campaign properties windows also include the list of all visited points in this
field campaign. With this list is easier to keep the history of all visited points in every
field campaigns.

The Visited Points can be created by clicking in button “Add…” on the Field Campaign
properties window (see Figure 6-14) and a new window will be open, Visited Point
properties window (see Figure 6-15). In this window is possible do add some
information about the weather conditions and some more useful information. The
weather conditions are very important to analyze the results measured on a distant
future.
The Visited Point properties window also allows attach files to the visited points, such
as sheets, photos and other documents. These documents are attached to each visited
point and not to the field campaign, so is possible to have different files attach to each
visited point. The files are also stored in the MOHID Studio database, so the file
location is possible and do not interfere with MOHID Studio.

6.2.7 Import from XLS Files
The import feature of XLS files to MOHID Studio is very useful and simple to use.
There are three different types of importation files: simple time series, moving time
series (profile) and boat cruise. Each importation file has a different format and there is
a demo file, of each type, that is installed along with your MOHID Studio. The demo
files are located on: My Documents\Mohid Studio\Templates\Data Import.
To import time series use the template “Import – TimeSeries.xlsx” and fill the values to
import. The time series template is only used for time series: date, time and parameter
value (see an example in Figure 6-17). After filling the template file, save the file with a
different name, keeping the template as is. The XLS file should be like the example on
the Figure 6-17. If there is a missing field in the line, all the line will be ignored. If the
line is empty or if the first field is empty or missing all values above will be ignored.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 8 4
Figure 6-17: Import Time Series Template
To import the time series values from XLS file to MOHID Studio use the Import Time
Series window (see Figure 6-18) from Environmental Monitoring tab in the group
“Import”. First choose the parameter, monitoring station and time series type fields for
the time series that will be imported and browse for the source XLS file. After the file is
selected MOHID Studio will display all time series values found on the imported file.
This process may take a while, depending on the quantity of values to import. The press
“Import” button to complete the importation process. This process also may take a
while, depending on the quantity of values to import.
If the file has some errors or does not follow the template file (Figure 6-17), MOHID
Studio will display the error. If the message is “No values found in file” please check if
the file is correct or if the template file is the correct type for the import window in use.

Figure 6-18: Import Time Series window
Figure 6-19: Import Boat Cruise window
When the time series results from a profile measure, and the depth field is required, the
right template to use is “Import – Profile.xlsx”. This file is very similar with the time
series import file (Figure 6-17) with an extra coordinate field: depth. The “Import –
BoatCruise.xlsx” file is used for boat cruise measures or measures that required
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 8 6
coordinates tracking. This template file is also similar with the others but has two extra
coordinate fields: Longitude and Latitude (see Figure 6-19).
The values imported from “Profile” and “Boat Cruise” file types will be available on the
Moving Time Series window (see Figure 6-11). To edit the imported values use the
Moving Time Series properties window (see Figure 6-12).
6.3 Reports
The Reports is one of the best ways to analyze and check all values from time series
results. There are several reports available (see Figure 6-2), that are configured through
the Report Window (see Figure 6-20) and are all fully described on the next sub-
sections.
Figure 6-20: Report Window – Parameter
The Report Window is composed by two sections: the report settings content (on the
left) and the generated report content (on the right) as showed on the Figure 6-20. The
bottom of left window (see Figure 6-21) is always composed by three sections:
Settings of selected report;
Time Interval;
Output.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 8 7
Figure 6-21: Report Window – Settings
The settings of selected report change in every report and will be described on the next
subsections.
The “Time Interval” (see Figure 6-21) allows the user to limit the results to a certain
time interval (for example: one day, one month, etc). If the box apply filter is not
checked, all values will be displayed.
The “Output” (see Figure 6-21) is the way to configure how the report will be displayed.
The report can be displayed on the right window of the Report window (as show on
Figure 6-20), PDF format or XLS format. For the last two formats, a location file and
name file are required. After pressing “Generate” button the report will be displayed on
window or saved in a file.
When a generated report is displaying on the Report window, the top bar of the
generated report content allows several features, such as: navigate through the generated
file report, print the report, save the report file as XLS format or/and PDF format, zoom
it and setting the page layout.
6.3.1 Report by Parameter
Reports by parameter, as the name say, are to generate reports based on parameter
values. This type of reports will show all values from a determine parameter, from all
monitoring stations. As an example, on the Figure 6-22 is a sample of a time series
values report by parameter, for the parameter “Temperature” with the Time Interval

from 01-01-2010 to 01-10-2010. The values are displayed alphabetical by monitoring
station name and by chronological date.
Figure 6-22: Report by Parameter
6.3.2 Report by Time Series
Reports by Time Series display all values for a parameter obtained (measured or
modeled) from one monitoring station. The list of parameters is displayed on the field
“Parameter”. After the “Parameter” is chosen, the list of time series displays all time
series available for that parameter. Choose the times series for the report, by selecting
the name. If there are measured and modeled parameters, it is possible to choose
between the two different types. To generate the report press the “Generate” button.
The values from Report by Time Series (see Figure 6-23) are displayed in chronological
time.

7 Tools
7.1 Introduction
MOHID Studio contains a set of tools. The majority of these tools works interactively
over the Map Visualization and provides the possibility to generate MOHID specific
data files.
MOHID Studio Tools can be accessed from the “Tool” menu (see Figure 7-1).
Figure 7-1: Tool menu
MOHID Studio tools are divided into: (i) geometry layers creation, (ii) grid creation,
(iii) grid data tools, (iv) watershed tools, (v) time series tools, (vi) HDF tools and (vii)
boxes tools.
Since tools work interactively over the map, some tools require creating one or more
temporary layers. These layers are added when the tool is started and removed when the
tool is closed.
Since tools work interactively over the map, MOHID Studio does not allow more than
one tool to be used simultaneously.
All tools are explained in detail next.
7.2 Geometry Layer Tools
7.2.1 Introduction
Geometry layers tools allow creating geometries interactively over the map. Normally,
geometries created with this tools, are used afterwards by other tools (e.g. points can be
used to create time series locations, polygons to define non compute areas, etc.).

7.4 Grid Data Tools
7.4.1 Introduction
Grid Data tools allow creating and modifying MOHID Grid Data Files. MOHID Grid
Data are used to provide MOHID data on a per grid cell basis (e.g. bathymetry,
topography, etc).
Using MOHID Studio’s Grid Data Tools, grid data can be created from a set of points
or a set of polygons.
7.4.2 Creating Grid Data from Points
Grid Data can be created from a set of points by selecting Grid Data -> Create from the
“Tool” menu (see Figure 7-1). This tool is typically used to create the digital terrain
model for the MOHID Water (bathymetry) and MOHID Land (topography) models.
Creating a Grid Data from points requires: (i) a grid on which the grid data will be
based, (ii) base data (points) which will be used to fill the grid data and (iii) polygons
which define non-compute areas (optional).
The tool appears docked on the right side of the main window as shown in Figure 7-7.

Under the “Select Grid” option the desired grid can be chosen. The non-compute areas
can be defined by selecting the “Pick” button and click over the map on the polygon
which defines a non-compute area. Several polygons can be selected.
The base information can be either XYZ Data or HGT layers. Multiply sources can be
selected. The interpolation option allows choosing the desired interpolation method.
After selecting the filename for the final grid data, the process button activates the
interpolation process. For large data sets or large grids, the interpolation process might
take a while. Through the progress bar is possible to analyze the process status.
7.4.3 Creating Grid Data from Shapefiles
Grid Data can be created from a set of points by selecting Grid Data -> Create SHP
from the “Tool” menu (see Figure 7-1). This tool is typically used to create files which
contain information about land use, vegetation or soil types for the MOHID Land
model.
Creating a Grid Data from ESRI Shapefiles requires: (i) a Grid Data on which the grid
data will be based (Non compute areas will remain the same as in the base grid data and
(ii) a Shapefile with polygons data. The tool appears docked on the right side of the
main window as shown in Figure 7-8.

Figure 7-8: Creating a Grid Data from Shapefile (Polygons)
After selecting the base Grid Data and the source Shapefile, it is necessary to select the
feature (e.g. land cover code) on which the value mapping is to be performed. After
selecting the desired feature, the analyze button must be pressed, in order to obtain a list
of distinguish features (e.g. forest, urban areas) in the shapefile. For each feature, a
value which will be assigned to the corresponding grid cells must be provided. These
values can be saved or loaded by using the Load / Save buttons.
After filling the Value Mapping, the Grid Data file can be created using the process
button.
7.4.4 Modifying a Grid Data
Grid Data can be modified by selecting Grid Data -> Modify from the “Tool” menu (see
Figure 7-1). The tool appears docked on the right side of the main window as shown in
Figure 7-9.

After selecting the Grid Data to modify under the “Select Grid Data” option, it is
possible to select the grid cells to modify over the map, using the “Pick” button. After
selecting the grid cells on the map, the selected cells get highlighted and appear in the
point list. After all points to modify have been selected, several operations can be
performed, by choosing the appropriate options in the “Math Operation” box.
Points can be transformed into “Compute Points” or “Non Compute Points” through the
“Open / Close non compute points” box.
After editing the Grid Data, changes can be persisted or discarded in the “Persist
Changes” box.
7.5 Watershed Tools
7.5.1 Introduction
Watershed tools allow preparing data files for MOHID Land. These tools include: (i)
depression removal, (ii) watershed delineation, (iii) soil depth and (iv) cross section
definition.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 3
7.5.2 Depression Removal
MOHID Land requires a depression free digital terrain model in order to run4. After
constructing a digital terrain model (topography), the depression removal tool can be
used to remove depression from it. Depression can be removed by sink filling or by
artifact removal.
The depression removal tool can be accessed by selecting Watershed Tools -> Remove
Depressions from the “Tool” menu (see Figure 7-10)
Figure 7-10: Depression Removal Tool
The depressions removal process involves several steps. First, the digital terrain (Grid
Data) from which the depressions are to be removed must be selected and the existing
depressions must be found by using the “Analyze” button. If depressions are found, they
are highlighted on the map and listed in the “List of depressions”.
4 This applies only if the river network is to be simulated. You can run MOHID Land also in a special
mode without drainage network. In this case, the DTM may contain depressions.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 4
Depressions listed in the “List of Depressions” can be individually removed by selecting
the up (remove by sink filling) and down (remove by artifact removal) buttons. Since
the removal of a single depression may create new depressions, the list of existing
depressions is automatically one individual depression has been removed.
Since the number of depressions can be very high, MOHID Studio includes an
algorithm to remove depressions in an iterative process. This can be done by pressing
the “Remove depressions by iterations” button. MOHID Studio will loop through all
depressions for the value of “Max. Iteration” (by default the value is 50 times).
Depressions containing less then “Max. cell filling” cells (the default value is 5) will be
removed by sink filling, others by artifact removal.
NOTE: For very narrow values or very flat areas the depression removal algorithm may
not work very well. It may be required to preprocess the digital terrain model first (for
instance with the Modify Grid Data tool).
When all depressions have been removed, the depression free Digital Terrain Model can
be saved in the “Persist Changes” box.
7.5.3 Watershed Delineation
Watershed delineation has two proposes: (i) specifying which grid cells drain to the
outlet (and as consequence distinguishing between compute points and non-compute
points) and (ii) creates the drainage network.
The watershed delineation tool can be accessed by selecting Watershed Tools ->
Delineate Basin from the “Tool” menu (see Figure 7-11). This tool requires a depression
free Digital Terrain Model.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 5
Figure 7-11: Watershed Delineation Tool
The watershed delineation process involves several steps. First the Digital Terrain
Model must be selected from the “Select DTM” box.
NOTE: In this box appear all Grid Data layer currently loaded into MOHID Studio’s
GIS engine, so it is the user that select the right (depression free) Digital Terrain Model.
The second step is to define the area threshold value, by default is 1 ha. This area
indicates from which drained upstream area river channel are formed. The coordinates
of the outlet must also be set. They can be obtained using picking on the map.
NOTE: Watershed delineation is required in order to run MOHID Land, since MOHID
Land can only run with one single outlet. This option is optional, because it can be
useful, in a first step, to generate a drainage network for the entire digital terrain model
and only in a second step delineate the watershed, since it is easier to locate the outlet
over the entire drainage network.
In the “Output Options” box, the desired output of the delineation process is specified.
To run MOHID Land, only the drainage network is required. Information about options
used during the delineation process should also be stored, since they are required for the
Basin Geometry module (Basin Geometry check box). All other output is not required,

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 6
but may be useful for graphical visualization (namely the “Delineation” – polygon
which defines the watershed).
7.5.4 Cross Section Definition
After watershed delineation, the nodes of the drainage network do not contain cross
sections. MOHID Land needs to have the cross sections defined, in order to run. The
Cross Section Definition Tool allows defining cross sections for all nodes in a drainage
network in a simple way. This tool can be accessed by selecting Watershed Tools ->
Cross Sections from the “Tool” menu (Figure 7-12).
Figure 7-12: Cross Section Definition Tool
Cross section definition involves several steps. First the drainage network for which the
cross sections are to be defined must by selecting from the Network box (SCREEN
SHOT REVISION REQUIRED). Then the typical cross sections must be defined for,
one for each Strahler order. Cross sections are defined as trapezoidal ones (top width,
bottom width and high). It is possible to define triangular sections by setting the bottom
width to zero.
After defining cross sections for all Strahler orders of the drainage network, the
drainage network file can be saved, by selecting the save button in the “Persist
Changes” box. (SCREEN SHOT REVISION REQUIRED)

7.5.5 Soil Depth
The Soil Depth tool allows creating additional files for MOHID Land: (i) soil depth, (ii)
bottom digital terrain model (iii) slope and (iv) initial ground water level. This tool can
be accessed by selecting Watershed Tools -> Soil Depth from the “Tool” menu (see
Figure 7-13).
Figure 7-13: Soil Depth Tool
The Soil Depth tool requires a depression free Digital Terrain Model, which should be
selected in the “Select Digital Terrain” box. The parameter to construct soil depth can
be set in the “Select Parameter” box. The Min Depth and Max Depth parameter indicate
the minimum and maximum soil depths, respectively. The Max Slope parameter
indicates the maximum slope which the tool should consider. From these parameters
the soil depth is linearly interpolated considering. Grid cells with zero slopes will have
maximum soil depth and grid cell with slope greater or equal to the maximum slope will
have minimum soil depth.
The water table parameter indicates the percentage of the initial water depth, in function
to the total soil depth. A value of 0% indicates that the initial water table is close to the
bottom, a value of 50% indicates that the initial water table is at half soil depth and a
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 8
value of 100% indicates that the initial water table is closed to the top (fully saturated
soil).
In the “Persist Changes” box the target files can be selected and saved.
7.6 Time Series Tools
7.6.1 Introduction
Time series tools have two functions: (i) create files which indicate to MOHID model
the location of time series and (ii) create files which contain time series.
7.6.2 Grid Time Series Location
The Grid Time Series Location tool allows creating files which contains the grid
location of time series points. This tool can be easily accessed by selecting Time Series
Tools -> Grid Location from the “Tool” menu (Figure 7-14).
Figure 7-14: Grid Time Series Location Tool
Creating a grid time series location file involves several steps. First the grid data which
will be used as base must be selected. In a second step the locations of the grid points
must be specified. This can either be done by adding data from a Named Points layer by

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 0 9
selecting the points interactively over the map. The grid data location is generated by
clicking the Save button. This tool allows saving, optionally, a XML Geometry file with
the point locations. This is useful for display proposes and for later editing of the grid
time series location.
7.6.3 Node Time Series Location
The Node Time Series Location tool allows creating files which contains the node
location of time series points. This tool can be easily accessed by selecting Time Series
Tools -> Node Location. It works exactly in the same way as the Grid Time Series
Location tool.
7.6.4 Time Series from Database
The Time Series from Database tool allows extracting time series from MOHID
Studio’s database, in order to generate boundary conditions from MOHID models. This
tool can be accessed by selecting Time Series Tools -> From Database from the “Tool”
menu.
Figure 7-15: Creating a time series from the database
This tool requires that there has been previously data imported into the database (there
are several ways to import values to database, check subsections: 6.2.3, 6.2.4 or/and

In this section is explained the administration of MOHID Studio.
9.1 Introduction
The Administration menu (see Figure 9-1) is the place where it is possible to change all
types of MOHID Studio configurations. On the “License Manager” group it is possible
to register, request and validate your MOHID Studio license (for more information read
subsection 9.2).
9-1: Administration Tab
The “MOHID Studio Settings” contains several buttons to configure the basic settings
of your MOHID Studio. On the “General” setting is possible to change the paths of
MOHID executables files, output directories and some MOHID interface options. The
“Reset Database” button resets the MOHID Studio database. All the data will be
erased from your MOHID Studio database (example: monitoring stations, time series,
parameters, etc.). After reset the database, it is not possible to restore/recover the
previous database and all the data will be lost.
Through the “MOHID Studio Help” is possible to get information about your MOHID
Studio version, get help from your MOHID Studio manual and it is also possible to
request professional help for your MOHID Studio version. Help can be also found on
the internet or in our site – check “Links” group at the menu “Home” (Figure 2-5).

9.2.1 Introduction
After installing MOHID Studio it will work for 30 days for an evaluation period.
Evaluation versions have restricted usage. In order to work with a licensed version of
MOHID Studio, the user needs to register and request a license (for more information
read MOHID Studio – Installation Guide).
There are two types of licensed MOHID Studio versions: MOHID Studio Express and
MOHID Studio Professional. Licenses are distributed on a single machine basis. Action
Modulers may provide other types of licenses upon request.
MOHID Studio Express license is free of charge and it is valid for six month period.
After this period you need buy a MOHID Studio Professional license or renew your
MOHID Studio Express license, if you want to keep using MOHID Studio Express.
MOHID Studio Express works with all features enabled, but with some restriction
(check restrictions on Table 4).
MOHID Professional Edition works without any restriction. License fees vary in
function of the requested license.

10.2 MOHID ASCII Files
10.2.1 Introduction
MOHID ASCII files are ASCII files which follow special formatting rules. These files
are used to provide all input information to the FORTRAN based numerical MOHID
models (MOHID Water, MOHID Land and MOHID River). Some output of these
models is also written in the format.
MOHID ASCII files are organized by keywords and information blocks, which can pile
up to three hierarchical levels and aggregate groups of keywords. This format can be
seen likewise a simple Mark-Up Language. File generation can be made manually,
using a text editor (like MOHID Studio’s Text Editor) or by tools (like MOHID Studio
Tools).
The maximum number of characters per line is restricted to 256. As each line contains
only one instruction, this restriction does not represent any practical limitation to the
user. Files can have blank lines and keywords don’t have to follow any specific order.
This reduces the effort of preparing input data files in a rigid format and reduces input
data errors. With exception to some cases, all the reading (keywords, keyword values,
blocks definition tags) are case sensitive. So caution is advised in the preparation of the
files because recognition is only achieved by full correspondence of characters in the
code and in the data files. The Figure 10-1 shows an example of a MOHID ASCII file,
with keyword, keyword values and blocks.

10.2.2 XYZ Files
XYZ Files are used to define a set of point with x, y and z coordinates. These files are
typically used to store information from bathymetric or topographic surveys.
XYZ Files are ASCII text file which extension should be *.xyz. XYZ Files contain a set
of blocks, each containing a set of point values. One block is delimited by the following
case sensitive keywords: <begin_xyz> and <end_xyz>.
A fourth column can be optionally included and it is handled as a character string which
can also be used as a legend for each point.
The Figure 10-2 shows an example of a three column XYZ MOHID ASCII File.

10.2.3 Line Files
MOHID ASCII Line files are used to store simple lines. The default extension for
MOHID ASCII Line files is *.lin. This file is organized in blocks, each containing the
vertices for a determined line. One block is defined by the following keywords:
<begin_line> and <end_line>. Note that these keywords are case sensitive.
One file can contain an infinite number of blocks. Inside each block there are 2 columns
and at least 2 rows, one for each vertex of the line. The left column relates to the XX
coordinates of a point and the right one to the YY coordinates. The Figure 10-3 shows
an example of an MOHID ASCII Line file.

10.2.4 Polygon Files
MOHID ASCII Polygon files are used to store polygons. The default extension for
Polygons files is *.xy. This file is organized in blocks, each containing the vertices for a
certain polygon. One block is defined by the following keywords: <beginpolygon> and
<endpolygon>. Note that these keywords are case sensitive. One file can contain an
infinite number of blocks. Inside each block there are 2 columns: the left relates to the
XX coordinates of the polygon vertices and the right one to the YY coordinates of the
polygon vertices. The Figure 10-4 shows an example of one MOHID ASCII Polygon
file.
Figure 10-4: Example of a MOHID ASCII Polygon file
10.2.5 Grid Files
MOHID ASCII Grid files are used to stores grid. The organization of this file is divided
into a header section and a grid spacing section. MOHID supports orthogonal
horizontal grids, which can be rectangular or curvilinear. The default extension for Grid
files is *.grd. The Figure 10-5 shows examples of grids that are supported by MOHID
Studio.
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3 1
Figure 10-5: Example Grids supported by MOHID
Note that in MOHID the i index refers to the YY axis and the j index to the XX axis.
For example grid cell (5, 2) is the fifth grid cell in the YY axis and the second in the XX
axis.
The header section contains information related to the grid global definitions, such as
the number of cells, the type of coordinate used, the origin coordinates of the grid, etc.
Below are shown the keywords supported in the header section of a Grid file.
ILB_IUB - Two integer numbers defining the minimum and maximum I values
along the Y-axis of the grid.
JLB_JUB - Two integer numbers defining the minimum and maximum J values
along the X-axis of the grid.
COORD_TIP - A flag which indicates the used coordinates type.
ORIGIN - Two real values, which indicate the origin of the lower left corner of
the grid.
ZONE - Integer values defining the UTM Zone where the bathymetry is located.
GRID_ANGLE - Counter-clock mesh rotation relative to the north. The base
point is the origin of the grid.
LATITUDE - Average latitude value used to compute Coriolis frequency and
solar radiation when metric coordinates cannot be converted to WGS84
geographic coordinates.
LONGITUDE - Average longitude value used to compute Coriolis frequency
and solar radiation when metric coordinates cannot be converted to WGS84
geographic coordinates.
CONSTANT_SPACING_X - Boolean defining if the spacing in the X axis is
constant
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3 2
CONSTANT_SPACING_Y - Boolean defining if the spacing in the Y axis is
constant
DX - Constant spacing distance in XX axis
DY - Constant spacing distance in YY axis
If the spacing is not constant, the grid spacing section contains information about the
grid spacing in the XX and YY axis namely through defining the grid cells corners
coordinates. This information is stored in blocks, one for each direction. The data is
stored inside a block defined by the following keywords: <BeginXX> and <EndXX>
for the XX axis and <BeginYY> and <EndYY> for the YY axis. Note that the
keywords of these block definition tags are case sensitive. Each value must be stored in
a single line. The values are read from left to right corner in the XX axis and from
bottom to top in the YY axis. The first value is always zero in both directions, being the
following values cumulative. The Figure 10-6 shows an example of an MOHID ASCII
Grid file.

10.2.6 Grid Data Files
MOHID ASCII Grid Data files relate 2D or 3D information to a grid. Grid data is stored
in an ASCII text file and has multiple and flexible formatting options. Grid Data files
are used to store one value per grid cell (for example for bathymetry, topography).
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3 4
MOHID ASCII Grid Data Files contain the same section like Grid files (header section
and grid spacing section) plus an additional data section.
The data section contains the values of the Grid Data. The data is stored inside a block
defined by the following keywords: <BeginGridData2D> and <EndGridData2D>. Note
that these keywords are case sensitive. It is possible to specify the values by giving a
list of all values of all the grid cells. Each value must be stored in a single line. The
values are read from the lower left corner to the upper right corner of the grid that is
values reading is done by row-column order. The first grid data values are read in the
following order: (ILB, JLB), (ILB, JLB+1), … (ILB, JUB), (ILB+1, JLB), …, (IUB,
JUB-1), (IUB, JUB). Note that the index “i” refers to the Y-axis and the “j” index to the
X-Axis. In this case, if you have a (IUB x JUB) grid then the list must have (IUB x
JUB) values.

link: http://www.mohid.com/wiki/index.php?title=Grid_Data
10.2.7 Drainage Network Files
MOHID ASCII Drainage Network Files are used to stores information about drainage
network. The organization of this file is divided into blocks defining single nodes and
blocks of defining links between nodes.
Single node blocks contain information related to each node which makes part of the
drainage network. Single nodes blocks are delimited by the <BeginNode> and
<EndNode> blocks.

A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3 5
Figure 10-7: Example Node Definition
Links between nodes are defined by blocks delimited by <BeginReach> and
<EndReach> blocks.
Figure 10-8: Example Reach Definition
Due to the complexity of these files, it is recommended to generate these files with
MOHID Studio’s Watershed delineation tool.
NOTE: More information about MOHID Drainage Network files can be found on the
following link: http://www.mohid.com/wiki/index.php?title=Drainage_network
10.2.8 Time Series Files
MOHID ASCII Time series files are used to store information varying in time. These
files serve as input and as output for the MOHID numerical programs. MOHID ASCII
Time Series files should contains have an extension *.sr* (e.g. *.srh, *.srm, etc).
Time Series files have a header section containing general definition about the series
(location, time units, and name) and data section.
The header section must define the following keywords:
NAME – Name of the Station to which the series belong;
COORD_X – X Coordinate of the station;
COORD_Y – Y Coordinate of the station;
SERIES_INITIAL_DATA - definition of the series initial data;
TIME_UNITS – Time units in which the data is given;
The data section is defined inside a block defined by the tags <BeginTimeSerie> and
<EndTimeSerie>. Inside the block data is formatted into columns separated by blank
spaces. The leftmost column defines the accumulated time, in the time units defined in
the header section and starting from the time series initial date, also defined in the
M O H I D S t u d i o – U s e r G u i d e
A c t i o n M o d u l e r s - w w w . a c t i o n m o d u l e r s . c o m 1 3 6
header section. The number of columns is limited by the default number of characters
allowed in one single line, which are 256. In order to read the properties (e.g.
temperature, salinity, wind speed, etc) associated to a certain column, a header line must
be present on the line just above the <BeginTimeSerie> tag. The number of properties
names in this header line must be equal to the number of columns in the data section
including the accumulated time column. The names must be separated by blank spaces,
thus properties names with blank spaces are not allowed. Blank spaces of properties
must be replaced by an underscore. The Figure 10-9 shows an example of a simple time
series file with one column and in the Figure 10-10 it is possible to see an advanced
example.

10.3 XML Files
10.3.1 Introduction
MOHID Studio uses XML files to store data of many kinds. Many of these files are for
internal use only and are not described here. XML Files suitable to be edited are XML
files which contain geometry information. These are described along the next
subsections.
10.3.2 XML Named Points Files
XML named points files are used to store “named points” and can be generated with
MOHID Studio’s tools. An example of a XML Named point file is shown in Figure
10-11.

10.4 Other Formats
10.4.1 HDF Files
HDF5 is a general purpose library and file format for storing scientific data. It is the
standard input/output format of spatial and/or temporal data sets in MOHID. Through
MOHID Studio’s integrated map engine it is possible to visualize data contained in
HDF files. Besides this, MOHID Studio includes tools to manipulate HDF Files and
export data from HDF files to other formats.
HDF5 itself does not define a standard of how to georeference data sets, nor how to
time reference data sets. In order to overcome this lack of definition, MOHID defines
some special rules how data inside a HDF file should be organized, in order to be
MOHID-HDF. For more information about this subject can be found at the following
link: http://www.mohid.com/wiki/index.php?title=HDF_file
MOHID’s modules produce HDF files which contain: (i) polygon (grid data) based data
sets, (ii) drainage network based information and (iii) lagrangian (particle) based data
sets.

10.4.2 ESRI Shapefiles
The ESRI Shapefile is a popular geospatial vector data format for geographic
information systems software. It is developed and regulated by ESRI as a (mostly) open
specification for data interoperability among ESRI and other software products.
MOHID Studio is able to disable data contained in ESRI Shapefiles. Some MOHID
Studio tools are based on ESRI Shapefiles and through file conversion it is possible to
convert between ERSI Shapefiles and other file formats.
