Abstract

In general the drainage network length measurement is done in a 2-dimensional space taking into account the features extracted from topographic maps. By using Digital Elevation Models (DEM), one can obtain more accurate results by replacing the drainage network segments with their 3-dimensional length. The method developed allows to quantify the difference between the length calculated either in a 2-dimensional or 3-dimensional space. The amplitude of this difference depends on the DEM resolution and on the topography. Several geomorphic parameters use the drainage network to provide geomorphologic information about the studied region
