Abstract
In the processes of Hydrological and surface analysis, Digital Elevation Model (DEM) data have been applied to obtain hydrological features, which provide as inputs to several models. Hence altitudes data are accessible from different sources with various spatial resolutions. The current research paper represents the precision and excellence of drainage network study resulted from DEM. The concurrence degree connecting two layers is very low down for spatial model, drainage density and river rate of recurrence in plain regions. The D8 model procedure used to get the flow direction. Our method uses the D8 model to get the flow directions for each and every one pixel in the DEM. Many geographic information systems are being updated that store topographic information as the primary data for analyzing water resource problems. ArcGIS 10.3 version was used to derive drainage networks, flow direction and flow accumulation from DEM for the study area of Suryapet region. Finally the prepared flow accumulation data superimposed with drainage data for valid verification.
