Title

AUTOMATED DRAINAGE NETWORK EXTRACTION USING DIGITAL ELEVATION MODEL IN GIS. A CASE STUDY.

Authors

Abstract

Although field mapping is acknowledged as the most accurate way to determine channel or drainage networks, it is often impractical and time consuming, especially for the large and remotely situated mountainous watersheds. Topographic maps, providing a useful surrogate for drainage networks, are the fundamental source for the drainage analysis. But, drainage analysis by manual delineation on topographic maps requires time and expertise, and subjectivity judgments. In this study for GIS based modeling, Digital Elevation Model (DEM) is used in presenting drainage networks, lineaments and geomorphic features. Drainage network delineation was performed using two methods: 1) Traditional method by hand delineation on 1/50,000 topographic map; and 2) Using TauDEM (Terrain Analysis Using Digital Elevation Models) model in ArcGIS 9.2 environment using SRTM DEM. The results revealing that the data extracted from the SRTM images are greatly equivalent to those obtained from the topographic maps 1:50.000 and providing more details in the lower stream orders, and morphotectonic parameters. The DEM suggests the tectonic influence on development of landscape.
