Dear all,
I am going to apply the TOPMODEL for the runoff.
There are many steps to do that and here are some concrete questions. But please know that I am using the ArcGIS 9.3. The given data I have is only a raster for the DEM.
1. There is something called CTI (Compound Topography Index) or it is known as the Steady state wetness index. How to generate it for a given watershed.
2. There is something called the Upstream Contribution Area, how to generate it as well.
Thanks
Taiseer
