[GRASS-user] footprint of a given volume of water.

[Matthew Perry]

Hi all,

I've used r.lake to answer the question "What land is inundated given
a X meter high dam?". In this case however, X is the unknown so I'm
trying to answer the question "How high does the dam have to be in
order to hold Y cubic meters of water?"  as well as to determine the
"inundation footprint".

I'm familiar with some engineering models that require much more
detailed cross-sectional information than we have available...
currently we have a high-res DEM as our sole source. Are there any
GRASS modules or scripts that I should take a look at?

Thanks for the input,
