Drainage Area Characterization
Description
The Drainage Area Characterization tool (Terrain Morphology) generates elevation, area and volume curves for a set of selected drainage areas. The function divides each drainage area into slices and calculates each slice's elevation characteristics, as well as the cumulative area and volume that are below the elevation of the top of the slice. These characteristics are stored in an output Drainage EAV table. The function works with a selected set of drainage areas or with all drainage areas within the input feature class if there is no selected set.
When a strictly positive extrusion value is specified, one additional slice will be created.
