TRANSCRIPT
The stated goals of the RESTOR-Hydro EU project (www.restor-hydro.eu),
financed by EACI, IEE, is to develop and set-up a database and the support to
use it. The aim of this work is to map the location and characteristics of historical
watermills, weirs and all kind of anthropic water obstacles that are currently
inoperative.
This paper describes the management of the underlying data and purposes
behind the RESTOR Hydro Mills Map Module.
The criteria are designed as an aide for the evaluation of historical sites: to
estimate decentralized power generation potential, relevancy for environmental
sites and an initial attempt to quantify the underutilized potential that currently
exists.
Approach for Romania
The purpose of the Mills Map is to upload over 1500 data points.
According to data provided by the “Romanian Waters” National
Administration was analysed the small accumulations lists for each water
catchment area of Romania.
The required minimum
data elements per site are:
GPS Coordinates
Historical Use
Restorable Condition
Power Availability
Methodology
To identify and mapping sites was used the method Internet Mapping,
Google Earth application and ArcGis topographic map.
The stream of the river can be easily located, by name, and explore up or
down a river and tributaries by clicking and dragging to pan through the map.
To estimate the Power Availability, the following formula is used:
P = 7 ˑ Q ˑ H [kW]
For the purposes of restoring a potential hydropower can be used:
Archimedes screw, very low head turbine and done using the classical
approach: with Vertical Kaplan turbines , Bulbs units or the siphon turbines.
All necessary disclaimers about data certainty and the actual availability of
power from a site should be included in any documentation.
Potential use is dependent on field measurements.
Set-up a database and the support to use and facilitating project
development.
Using the geographical coordinates of the sites, it was possible to map them
for quick visualization.
Repowering abandoned sites results in the generation of hydroelectric power
for local use and for injection to the electrical grid, increasing electricity
production from renewable sources.
Authors opinion about the project that this is the only really sustainable way
to further develop the hydropower potential – using the thousands of historic
sites of water use, as: water wheels, linen mills, sawmills, weirs.
Conclusions
Thank you !
