Hi there<br>
<br>
I reckon it will be great to have a set of plugins for hydrology and<br>
hydraulic modelling in QGIS.<br>
<br>
<br>
To develop a new hydraulic engine for QGIS is not an ideal and we will<br>
be re-inventing the wheel. So, the ideal situation is to take an<br>
existing tool and use QGI to pre-process or post-process the<br>
inputs/outputs.<br>
<br>
<br>
Most of the hydraulic/hydrology model I have come across are for Windows<br>
only, which is not ideal.<br>
<br>
<br>
The only one which is very powerful and really multi-platform is AnuGA<br>
<a href="http://sourceforge.net/projects/anuga/" target="_blank">http://sourceforge.net/projects/anuga/</a><br>
<br>
AnuGA can be used for modelling: coastal, fluvial, surface water and<br>
urban drainage system.<br>
<br>
We have developed a plugin for QGIS so that you can prepare your model<br>
GIS files (boundary files, mesh, etc). It is a bit out of date and<br>
requires lots of tweaking.<br>
<a href="http://sourceforge.net/projects/anuga-gai/" target="_blank">http://sourceforge.net/projects/anuga-gai/</a><br>
<br>
Will be good find a fund from those who are interested and develop this<br>
further. We have several ideas to improve the plugin further (mesh<br>
editor, result viewer, etc) but extremely busy atm.<br>
<br>
Cheers<br>
