MORPHOMETRIC ANALYSIS OF BAUR CATCHMENT IN LESSER HIMALAYA: USING GEO-SPATIALTECHNIQUES

The current assessment is an undertaking to evaluateand compare variousmorphometric parameters of the Baur catchment. Morphometric analysis of the river basin provides a quantitative description of the drainage system, which is an important aspect of the categorization of the basin (Strahler, 1964).The Baur catchment is located in the outer part of the Lesser Himalaya in the Kumaun region, which is a major part of Western Himalaya.The geographical area of Baur Catchment is 106.233Km2.Morphometric analysis of Baur Catchment includes linear, areal, and relief aspects.The calculation of the morphometric parameter, along with map preparation, was performed with the help of GIS techniques and ancillary material.Most of the area of Baur Catchment is occupied by Siwalik Group (sandstone and clay intercalation with pseudo-conglomerate) of rocks.The entire Baur Catchment has found 6th order drainage, which reveals sub-dendritic to a dendritic type of drainage pattern. It is observed that the drainage density of the Baur Catchment is 3.525 km/halfkm2.
