abstract
The study of morphometric parameters plays a vital role in understanding and managing watersheds, making it a an essential component of hydrological surveys. It is most significant for soil and water conservation recharge structure development, planning and management. A morphometric analysis of Pingalgarh watershed of VNMKV has been carried out using geoprocessing techniques. This technique is found suitable for the extraction of Pingalgarh watershed and its drainage networks. The analysis of Morphometric parameters viz; form factor, elongation ratio, circulatory ratio, Relief ratio, drainage density, stream frequency, bifurcation ratio, ruggedness number, stream order, stream length, etc., are calculated with the help of Arc GIS 10.8 software and Digital elevation model. The watershed area is 30.43 Sq. Km covered and drainage shows dendritic and sub-dendritic drainage pattern with stream orders of sub-basins were found ranging from I to V orders. There are one 5th order, three 4th order, twelve 3rd order, forty sixth 2nd order and one hundred ninety-nine 1st order streams are found in study area. The total stream length of study area is 119.983 km. The drainage density value being as 3.943 km/km2. Mean bifurcation ratio value is 3.790 which shows that mean of bifurcation ratio for entire basin is under range of 3.0 to 5.0. The values of basin fall under the range of bifurcation ratio in which the geologic structures do not distort the drainage pattern. The study is advantageous in water and land resource progress plan with the help of remote sensing and GIS techniques.
