Detailed Description

English {{currentDetailLanguage}} English

Quoted From : https://hydrology.usu.edu/taudem/taudem5/help53/PitRemove.html

    Pit Remove is the phenomenon of filling, retaining and storing in the surface potholes caused by rainfall or melting water.

    Pits, also referred to as depressions or sinks, are low elevation areas in digital elevation models (DEMs) that are completely surrounded by higher terrain. They are generally taken to be artifacts that interfere with the routing of flow across DEMs, so are removed by raising their elevationt, or filling them, to the point where they drain off the edge of the domain. The pour point is the lowest point on the boundary of the "watershed" draining to the pit.
