摘要：In the present paper, an attempt has been made to study the detail morphometric characteristics of Jaipanda Watershed in Silabati river basin, West Bengal. For detailed study, we used ASTER data for preparing digital elevation model (DEM), and geographical information system (GIS) was used in evaluation of linear, areal and relief aspects of morphometric parameters. Watershed boundary, flow accumulation, flow direction, flow length, stream ordering have been prepared using Arc-Hydro Tool; and contour, slope, aspect, hillshade have been prepared using Surface Tool in Arc-GIS 9.3 software, and ASTER (DEM). Different thematic maps i.e. drainage density, slope, relief, superimposed profile, and longitudinal profiles have been prepared by using Arc-GIS software. Authors have computed more than 20 morphometric parameter of all aspects. Based on all morphometric parameters analysis; that the erosional development of the area by the streams has progressed well beyond maturity and that lithology has had an influence in the drainage development. These studies are very useful for planning rainwater harvesting and watershed management.
