The present investigation intends to examinations the morphometric attributes of Ozat River basin to comprehend the hydrogeological behavior and influence on hydrology of the basin. The basic and derived morphometric parameters (linear, areal and relief aspects of drainage network) for the basin were determined using ASTER DEM (30 m resolution),remotely sensed images of Linear Imaging Self Scanner III (LISS III) and Geographic Information System (GIS). The maps for the topic of land use/land cover, soil, drainage, slope and contour were prepared and investigation was made for the said subjects utilizing the ArcMap V10.1. The drainage area of the basin was found to be 3176.24 km2 and shows sub-dendritic to dendritic drainage pattern. The study area designated as 7thorder basin with the drainage density value being as 1.46 km/km2. The slope of the basin varies from 10% to 50%. The mean bifurcation ratio was 3.96 represent geological heterogeneity, high permeability and less structural control. The results of the morphometric analysis reveal that Ozat River Basin is elongated with high erosion and peak flow. It has a strong relief and steep ground caused severe erosion and down cutting activity in the past and it is still susceptible to surface erosion at present. The morphometric properties determined for this basin as entire and for every watershed will be valuable for the sound planning of water harvesting and groundwater recharge projects on watershed base.
