Abstract


In the study, an attempt has been made to slope and its analysis units in of B-13TAU031 (Upper Tapi sub basin) subwatersheds, Central India, using integrated SRTM DEM, remote sensing and Geographic Information System (GIS) techniques especially Shuttle Radar Topographic Mission (SRTM), Digital Elevation Model (DEM) of 90 m resolution by analyzing the elevation, slope and image characteristics. Geologically, study area consists of Deccan trap and Purna alluvium From the DEM and satellite data the structure, processes and factor are clearly observed on the landforms, which give a complex appearance to slope profile. The steep escarpment slope which are followed by the talus slope or debris slope with convex profile make it clear that DEM and satellite data plays very important role in the landform delineation. The area shows the slope from level category to very steep slope. The majority of the study area mainly covered by level to gentle category slope while the steep slope can be observed south east and south west part of the study area.
