Catchment

Definition

A catchment is an area of land that is drained by a river and its tributaries. Delineation can be made based on the topographic divide (watershed) using digital terrain models (DTM) and a Geographic Information System (GIS). DTMs are freely available online from a variety of sources, such as the 30 m resolution ASTER GDEM from NASA and Japan Space Systems (http://asterweb.jpl.nasa.gov/gdem.asp).
