Abstract
In this study, morphometric analysis and prioritization of the eight miniwatersheds of Mohr watershed, located between Bayad taluka of Sabarkantha district and Kapadwanj taluka of Kheda district in Gujarat State, India is carried out using Remote Sensing and GIS techniques. The morphometric parameters considered for analysis are stream length, bifurcation ratio, drainage density, stream frequency, texture ratio, form factor, circularity ratio, elongation ratio and compactness ratio. The Mohr watershed has a dendritic drainage pattern. The highest bifurcation ratio among all the miniwatersheds is 9.5 which indicates a strong structural control on the drainage. The maximum value of circularity ratio is 0.1197 for the miniwatershed 5F2B5b3. The miniwatershed 5F2B5a2 has the maximum elongation ratio (0.66). The form factor values are in range of 0.29 to 0.34 which indicates that the Mohr watershed has moderately high peak flow for shorter duration. The compound parameter values are calculated and prioritization rating of eight miniwatersheds in Mohr watershed is carried out. The miniwatershed with the lowest compound parameter value is given the highest priority. The miniwatershed 5F2B5b2 has a minimum compound parameter value of 3.12 is likely to be subjected to maximum soil erosion hence it should be provided with immediate soil conservation measures.
