Measurement Of Watershed Geometry In The Central Part Of Udaipur Sector, Rajasthan Using Remote Sensing And Gis

Watershed is a naturally occurring hydrologic unit with similar physical, topographic and climatic conditions. Watershed behavior can be understood by the study of morphometric parameters which helps to make a various plan for sustainable development by using the natural resources. This analysis can be achieved through measurement of linear, aerial, and relief aspects of the watershed. The total of 11 subwatershed of the Ahar watershed of Udaipur district was individually analyzed. SOI toposheet map, ASTER DEM, SRTM DEM, and satellite imageries were used to delineate the stream network as well as making several maps under GIS environment. GIS is very powerful tool for regional as well as micro level watershed study
