The second day of the Winter School on GEOframe is dedicated to the watershed delineation and hillslope extraction. First the relevant concepts are given. Then GEOframe (Horton Machine) tools are used to get the desired results.
We recovered something from the first day.
- Hydrogeomorphology: the basic theory (YouTube video 2019,YouTube2020)
