Hi all,
I have calculated a volume of water obtained from Hydrologic Study. Now make it, I want show how this volume fills DEM of 1 meter of resolution and what level have to the low point of raster. It's possible do this in SAGA GIS?
Thank you-
Antonio

Hello Antonio,

could you please clarify with a bit more details the type of procedure or calculation that you would like to apply to your data.

Thanks,
Olaf

I have a volume of water that it's for example 50000 cubic meters. Now i want know how this volume will be distributed within in my DEM so i view what zones are interested of inondation and what no.
I hope to be more clear.
Thanks

Hi Antoinio,

unless you have a complete flat water level this would require a 2D hydraulic simulation. Such a tool is not available in SAGA. For a flat water level you can have a look at the Terrain Analysis > Hydrology > Lake Flood tool, although this requires another input than the amount of water in cubic meters.

Best regards,
Volker
