Hi. I need an open source QGIS friendly software to model runoff in a big basin in Africa (17.000 km2). I know how to do it in Hec-Hms but it seams a bit amateur, because the choice of CN depends on user criterion. I would prefer to use a software that use DEM to calculate runoff. In the other hand, and as far as I know, Hec-GeoHMS works only with ArcGIS. Am I right?
Can someone tell me the pros and cons of IHACRES, TOPMODEL and EPA BASINS/HSPF ?
Hi Jorge,
I think that QGis does not have a direct tool for runoff models. I recommend you use QGIS to process the spatial information and R-CRAN for the model.
As an alternative, you can use GRASS GIS with qgis. in this web you have several modules.

hi,
you can use free SAGA software for hydrological models.

Try ArcSWAT, they have recently made an interface to use qGIS with SWAT, Just introduced. OR use ArcGIS interface SWAT model. Most common.
Hi,
SWAT+ fits for your goal. The following paper explain step by step simulation process:
