Abstract

Remote Sensing and GIS techniques have been proved to be efficient tools in the delineation updating and morphometric analysis of drainage basin The present study incorporates a morphometric analysis of three subbasins of Fatehabad area of Agra district using remote sensing and GIS techniques The morphometric parameters of the subbasins are classified under linear areal and relief aspects The drainage pattern exhibited by the main river Yamuna and its tributaries shows a dendritic pattern indicating homogenously underlain material while the mean bifurcation ratio values suggest that the geological structures are not disturbing the drainage pattern The form factor value of subbasins suggests that the main basin is more or less elongated Circularity ratio values of the three subbasins fall within range of elongated basin and low discharge The area has low density indicating that the region has high permeable subsoil material and dense vegetation The values of drainage texture drainage density and infiltration number indicate that subbasinIII has the highest infiltration rate and low runoff hence contributing most to the underground water resources This study also indicates porous and permeable subsoil condition in subbasinIII The values of subbasinI indicate low permeable subsoil material owning to high infiltration number value hence low infiltration and high runoff
