This day is dedicated to watershed delineation and hillslope extraction. First the relevant concepts are given. Then the [Horton Machine][1] tools are used to get the desired results. Morning session - [Planning the catchment analysis: the seven steps of hydrological analysis][2]; - The catchment landscape: form, organization, types; - Hydrogeomorphology: the basic theory; - Exercise with DEM for extracting the basic features. Afternoon session - Hydrogeomorphology: the derived quantities; - Exercise with DEM for extracting the derived quantities; - Hydrogeomorphology: hillslope-link partition of the basin; - Exercise on hillslope-link partition of the basin; - The GEOframe Input builder new tool. [Here][3] you can find the test case presented during the School, and [here][4] the template of the OMS project to try out your own case study.
