catchment

Delineate catchments and basin maps for mHM/mRM setups.

The module builds hydrologic grids from flow direction or DEM data, supports global and local domains, single- and multi-gauge delineation, outlet matching by area or shape, and writes basin ID, idgauges, mask, gauge metadata, and basin shape outputs.
