Material for the GEOframe Winter School - Catchments and Hydrologic Response Units delineation

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.

Requirements: if not already done, install numpy and rasterio with anaconda. These will be used to visualise the maps produced by the OMS Horton Machine tools.

Day 2 actual schedule ... We recovered something from the first day.
