Abstract

Surface topography of any drainage basin plays an important role in the development
of drainage networks and its evolution. Basin hydrology is also controlled by topographic
attributes as the overland flow, through flow and stream flow are largely determined by relief
and slope. Topography largely affects the evolution of landforms and slope, vegetation growth,
and soil development. So it is necessary to quantify the various parameters of topography in
order to get the economic design for river utilization and control, as well as watershed
development and planning. In the present study an attempt has been made to evaluate existing
topographic condition of the Ramganga River Basin by using ASTER GDEM data. Geographic
Information System (GIS) was used for calculating and mapping. The study reveals that the
nature and variations of surface and relief parameters are largely affected by the topographic
variability.
