    Introduction to Delft3D-DIDO

    2.1 Introduction

    Vergilius once wrote: The Tyrian princess Dido succeeded the father and became queenof Tyrus. Her brother Sichaeus had killed her husband, after which she fled via Cyprus toAfrica. There she asked a local king the favour to give her as much land as she could spanwith the hide of a bull. When the king granted the request, she cut the hide into long, thinstrips enabling to span a much larger area. On this area Carthage was founded.

    Feel yourself in the position of DIDO with the mouse and your computer screen, to fit thereal world to your needs.

    2.2 Functional description

    Delft3D-DIDO is an interactive grid editor for coupling hydrodynamic models with the DEL-WAQ model, Deltares (2008b). It uses a rectilinear, curvilinear or Finite Element hydrody-namic grid layout as input. It produces the administration file needed by the Delft3D Waterquality model DELWAQ to condense the fine hydrodynamic grid to a coarser water qualitygrid. Each water quality grid cell consists of an integer multiple of the hydrodynamic gridcells. Using Delft3D-DIDO without aggregation will produce a DELWAQ aggregation inputon the original hydrodynamic grid spacing, although DELWAQ grid cells will be renumbered.

    This means that Delft3D-DIDO does NOT make grids, but modifies existing hydrodynamicgrids for use in water quality- and ecological modelling. Delft3D-DIDO does so by defininga pointer from each of the hydrodynamic grid cells to a water quality grid cell. This meansthat after operation of Delft3D-DIDO each hydrodynamic grid cell has a DELWAQ waterquality/ecology grid cell numbering.

    2.3 Implementation specific aspects

    Although Delft3D-DIDO can support a variety of hydrodynamic grid structures, your versionwill generally be limited to operate in concert with the hydrodynamic models available atyour site. At the point where you are able to import a hydrodynamic grid, you will generallyonly be confronted with a selection screen showing the hydrodynamic grid files supportedby your installation. Since this manual is general, certain sections will refer to options that

    Introduction to Delft3D-DIDO Delft3D-DIDO

    User Manual

    are masked(e. g. a regular aggregation of every m x n grid cells is meaningless for irregularlylinked grids and most finite element grids).

    The output of the supported hydrodynamic models is as such insufficient for DELWAQ sim-ulations. It is input to a coupling program between the supported hydrodynamic model andDELWAQ. The coupling programs between the hydrodynamic program, or the hydrodynamicprogram itself (e. g. Delft3D-FLOW) accept the aggregation output file of Delft3D-DIDO andproduce the administration and hydrodynamic input files for Delft3D-WAQ.

    Getting started

    3.1 Overview of Delft3D

    The Delft3D program suite is composed of a set of modules (components) each of whichcovers a certain range of aspects of a research or engineering problem. Each module can beexecuted independently or in combination with one or more other modules.

    Delft3D is provided with a menu shell through which you can access the various modules. Inthis chapter we will guide you through some of the input screens to get the look-and-feel ofthe program. In the Tutorial, Chapter 6, you will learn to define a simple scenario.

    3.2 Starting Delft3D

    To start Delft3D:

    On an MS Windows platform: select Delft3D in the Programs menu. On Linux machines: type delft3d-menu on the command line.

    Next the title window of Delft3D is displayed, Figure 3.1.

    After a short while the main window of the Delft3D-MENU appears, Figure 3.2.

    Several menu options are shown. For now, only concentrate on exiting Delft3D-MENU, hence:

    Click on the Exit push button.

    The window will be closed and you are back in the Windows Desktop screen for PCs or onthe command line for Linux and UNIX workstations.

    Remark:

    In this and the following chapters several windows are shown to illustrate the presen-tation of Delft3D-MENU and Delft3D-DIDO. These windows are grabbed from thePC-platform. For Linux workstation the content of the windows is the same, but thecolours may be different.

    To continue start the menu program again as indicated above.

    Click the Grid button.

    Next the selection window for Grid and bathymetry is displayed for preparing a curvilineargrid, interpolate data on that grid and aggregate the hydrodynamic cells, see Figure 3.3.

    Before continuing with any of the selections of this Grid and bathymetry window, youselect the directory in which you are going to prepare scenarios and execute computations.

    Click the Select working directory button.

    Next the Select working directory window is displayed, see Figure 3.4 (your currentdirectory may differ, depending on the location of your Delft3D installation).

    Browse to and open the sub-directory of your Delft3D Home-directory. Open the directory. Enter the sub-directory and close the Select working directory

    window by clicking button OK, see Figure 3.5.

    Next the Grid and bathymetry window is re-displayed, but now the changed currentworking directory is displayed in the title bar, see Figure 3.6.

    Remark:

    In case you want to start a new project for which no directory exists yet, you can selectin the Select working directory window to create a new folder.

    5.1.8 Flow attributes

    Dry points for the hydrodynamic module Delft3D-FLOW or SIMONA need to be incorpo-rated when generating the aggregation, see Figure 5.6. The dry points are needed whengenerating the aggregation because the dry points are not involved in the hydrodynamiccomputation and do not have a cell/segment number. Dry points for the hydrodynamicmodule Delft3D-FLOW can be defined in two ways: either using the Visualisation Areawindow of the FLOW Graphical User Interface, or, using Delft3D-QUICKIN. See the SI-MONA user manual Rijkswaterstaat/RIKZ how to define dry points for the hydrodynamicmodule SIMONA.

    5.3.1 Change centre of projection

    For spherical co-ordinates Delft3D-DIDO can use two different projections, no projectionand stereographic projection. For stereographic projection a special function is implementedto centring the computer screen to the centre of projection and the sphere. This functioncan be invoked by clicking the menu item Operations Change Centre of Projection seeFigure 5.11. When using this command the centre of the projection is set to the centre ofthe screen. This action requires recalculation of the projection and a new screen refresh. Thecentre of the projection does not change when using zoom in, zoom out or pan, so there isno performance drawback and a smooth screen-refresh is obtained.

    Before you end your Delft3D-DIDO session you have to save the results from the aggregation.The aggregation can be saved to file.

    Choose the menu option File Export Aggregation. and the Save Aggregation windowwill be opened (Figure 6.6)

    Or choose the menu option File Save Project As and the Save Project window will beopened (Figure 6.7). After saving the project file () the window Save Aggregationto save the aggregation file will appear (Figure 6.8).

    The advantage to save the aggregation in a file is that the reference to all the gridsand their aggregation are saved, especially for multi domain models this is an advantage.

    6.7 TELEMAC grid files

    TELEMAC users can also use Delft3D-DIDO to aggregate the water quality grid cells.TELEMAC is an hydrodynamic program which uses unstructured collocated triangular grids(see Figure 6.9).

    Figure 6.9: TELEMAC hydrodynamic triangular grid

    Due to the collocation of the variables in TELEMAC and the need of finite volumes in thewater quality program Delft3D-WAQ, see Deltares (2008b), the hydrodynamic grid and thewater quality grid are different, as seen by comparison of the Figures 6.9 and 6.10

    The aggregation of water quality cells is not as straightforward as for structured grids withstaggered variables used in Delft3D-FLOW. For Delft3D-FLOW and Delft3D-WAQ the hy-drodynamic grid and the default water quality grid is the same. For unstructured grids weallow two different options of aggregation

    1. Default aggregation

    2. Aggregate at most three cells together

    The default aggregation means that all finite volumes around the hydrodynamic grid nodes(indicated

    For a three cell aggregation choose the menu-option Edit Regular, you can click theintersection point of three different volumes to aggregate this cells. These three cells will bethe starting point of the algorithm to aggregate as much as possible three hydrodynamic cellsto one water quality cell. Due to the irregularity of the grid you will see that some waterquality cells are not aggregated and others are just aggregated to their neighbour.

    Click on intersection point Click on the right mouse button to obtain the aggregation for the whole area, Figure 6.11

    Figure 6.11: Aggregated Finite Volume grid

    All other options of Delft3D-DIDO can also be used in combination with a TELEMAC grid.

Astronomic and harmonic forced boundaries must be specified before QH-relation forced

    boundaries, which in turn should be specified before time-series forced boundaries.

    Astronomic and harmonic forced boundaries cannot be combined.

    Example:

    Two boundary sections with data type A(stronomic) and one with type T(ime series).

    The grid indices of the begin and end point of a dry section (4 integers).

    Restrictions:

    The angle of a line of dry points and the horizontal numerical grid axis can be an integermultiple of 45 degrees.

    Dry points may not be defined along the model boundaries (which by default lie alongthe lines M = 1, N = 1, M = Mmax or N = Nmax). Therefore, the indices of thesepoints must lie between M = 2 and Mmax-1 and N = 2 and Nmax-1, respectively.

    The input items are separated by one or more blanks. The most lower-left dry point has indices (2, 2).

    Example:

    Five sets of dry points in a model area of 19 * 8 grid points, see Figure A.1.
