About the interaction of GRASS and HEC-RAS we have developed a grass script named r.inund.fluv, that interpolate the results of a normal 1D river model and allows to obtain a 2D flooding maps. It works quite well and you can see documentation on the add-on web page (http://grass.osgeo.org/wiki/GRASS_AddOns#r.inund.fluv)
The idea is quite different to that of Thomas, that describe a tool similar to HecGeo-Ras that works with proprietary softwares. However also two similar GRASS tools have been developed by Piergiorgio Chiraz & Andrea Ricci . I don't know exactly where and how are available and I found only italian documentations, but you can ask directly to the authors. I think that the implementation of 2D model in GRASS is more complicated, but a good idea! We try it with a dam break flooding model 2d that we are developing at Institute of Earth science and will be available in the next weeks (http://istgeo.ist.supsi.ch/site/projects/dambreak). Good luck and at your disposal for any questions! Roberto aquavitae wrote: > > Thanks for all the replies.
