Abstract:
In this study, Prioritization of Meghal River basin, Gujarat, India was carried out by using remote sensing (RS) and geographical information system (GIS). Watershed Morphometric such as Bifurcation ratio, Stream Frequency, Length of overland flow, Texture Ratio, Drainage Density, Elongation Ratio, Form Factor, Circulatory Ratio and Compactness Coefficient were used for Prioritization of the basin. River basin was divided in 7 mini-watershed based on the drainage pattern i.e., 5G1D2a1, 5G1D2a2, 5G1D2b1, 5G1D2b2, 5G1D2b3, 5G1D2c1 and 5G1D2c2. Based on the importance of morphometric parameter, priority ranks were assigned to the morphometric parameters of each 7 mini-watershed. Weighted aggregated rank was calculated from ranks of each parameter. Mini-watershed 5G1D2c2 with least weighted aggregated rank 3.0 is given highest priority for conservation efforts followed by 5G1D2b1, 5G1D2b3, 5G1D2b2, 5G1D2c1, 5G1D2a2 and 5G1D2a1 with weighted aggregated rank value of 3.1, 3.7, 4.0, 4.6 and 4.7 respectively.
