Abstract

Digital Elevation Model (DEM) is used to determine terrain attributes and geomorphologic attributes.  The geographic information system and the Arc Hydro tool are used to extract various hydrologic information and to describe various characteristics of the catchment area. The procedure includes the: DEM reconditioning and stream network generation. Extracted hydrologic information is essential for hydrologic analysis and to provide support for water resource management.

Keywords: Digital Elevation Model, Hydrologic Information, Arc Hydro.
