Abstract:
Biriyakhedi micro-watershed is part of Kalisindh, Chandrabhaga catchment covering an area of 1648.28 ha in Jhalrapatan tehsil of Jhalawar district in south eastern Rajasthan. The morphometric parameters of the basin can address linear, areal and relief aspects. The present study deals mainly with the geometry, more emphasis being placed on the evaluation of morphometric parameters such as stream order (Nu), stream length (Lu), bifurcation ratio (Rb), drainage density (Dd), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ratio (Rc), and form factor ratio (Rf) etc. The GIS based morphometric analysis of this drainage basin revealed that the Biriyakhedi micro-watershed is 4th order drainage basin and drainage pattern is sub-dendritic to dendritic type. It indicates the homogeneity in texture and lack of structural control. Total number of streams is 125 in which 93 are first order, 23 are second order, 8 are third order and 1 is fourth order streams. The length of stream segment is maximum for first order stream and decreases as the stream order increases. The drainage density (Dd) of study area is 3.5 km/km2. The low value of bifurcation ratio (4.04) revealed that the drainage pattern is not affected by the geologic structures. High value of elongation ratio has flat land with low relief and low slope (0.47) compare to circulatory ratio (0.61) indicates elongated shape of the micro-watershed. Low value of drainage density (3.5 km/Sq km) shows that the region is having coarse permeable sub stratum material under vegetative cover and watershed relief is low. Relief ratio (0.052) and relative relief (0.28%) reflects that the watershed can be treated with soil and water conservation measures. This study would help the local people to utilize the resources for sustainable development of the micro watershed.
