Morphometric Analysis of Mini Watershed of Upper Sabarmati River Basin

The morphometric analysis couple with geographical information system and remote sensing which is used for evaluates various parameters for the development of Sabarmati watershed of sabarkantha district, Gujarat. The upper part of the watershed shows parallel-sub parallel and rectilinear drainage pattern indicative of structural control, whereas the lower part shows dendritic drainage pattern revealing the homogeneity in texture and lack of structural control. The elongated shape of the watershed indicated the values of bifurcation ratio, circulatory ratio and elongation ratio. If the high values of drainage density, stream frequency, infiltration number and drainage texture indicate the study area is underlain by impermeable rocks which responsible for high runoff. So, the result of this analysis useful in determining the effect of watershed characteristics such as size, shape, slope of the catchment on runoff etc.
