Abstract 

The quantitative analysis of the watershed is important for the quantification of the channel network and to understand its geo-hydrological behavior. Assessment of drainage network and their relative parameters have been quantitatively carried out for the Baink watershed of Madhya Pradesh, India, to understand the prevailing geological variation, topographic information and structural setup of the watershed and their interrelationship. RS & GIS has been used for the delineation and calculation of the morphometric parameters of the watershed. The Bank watershed is sprawled over an area of about 433.75 km with dendritic, parallel and trellis drainage pattern. It is sub-divided into seven sub-watersheds. The study area is designated as sixth-order basin and lower and middle order streams mostly dominate the basin. The main watershed had a drainage density value 1.46 km/km2 while rest of 7 sub watershed had drainage density value range from 1.35 to 1.59 km/km2 fells in its low category with high precipitation. The results from the morphometric assessment of the watershed are important in water resources evaluation and its management and for the selection of recharge structure in the area for future water management. 

Key words: Watershed Bifurcation Ratio, Elongation Ratio, Morphometry, RS and GIS
