Abstract:
In this study, Morphometric analysis and prioritization of the five sub-watersheds of Barna watersheds located in Raisen district of Madhya Pradesh, 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, and texture ratio, Length of overland flow, form factor, circulatory ratio, elongation ratio, and compactness ratio. The Barna watershed has little Parallel & Radial drainage pattern but mainly dendritic drainage pattern. The maximum value of bifurcation ratio is 3.000 for the sub-watershed No. 5D4A2b. The bifurcation ratio among all the sub-watersheds is ranging between 1.795 to 3.000, which indicates Lower Rb values are the characteristics of structurally less disturbed watershed without any distortion in drainage pattern. The sub-watershed No. 5D4A2b has the maximum value of circulatory ratio 0.4108, maximum value of elongation ratio 0.6257 and maximum value of form factor 0.3073. The form factor values are in range of 0.2662 to 0.3073 which indicates the elongated shape of the basin and having flatter peak flow for longer duration, which helps to manage the flood easily than those of the circular basin. The compound parameters values are calculated and prioritization ranks for all five sub-watersheds is carried out. The sub-watershed with the lowest compound factor is given the highest priority. The sub-watershed No. 5D4A2b has a minimum compound factor of 2.4 is likely to be subjected to maximum soil erosion, hence it should provided with immediate soil conservation measures.
