Hello to everyone:
I'm studying an active fault and I'm trying to use the SL or Hack Index (Hack, 1972). I've read a lot of papers that use this index, and I understand the theory, but I don't know how to compute it or applied it with the computer.
I have the DEM, the watershed, the main stream, etc. all on GIS, so now I need to compare the SL index profile and the elevation profile and find knickpoints.
Thank you!!!
Sebastián
