Abstract
In the present study, morphometric analysis has been carried out using Geographical Information System (GIS) techniques to assess the geo-hydrological characteristics of Sandran drainage basin with an area of 318.25 km 2 located in the south-eastern part of Anantnag district, Jammu and Kashmir, India. The basin is characterized by dendritic to sub-dendritic drainage pattern in the upper part of the catchment, and more or less parallel in the lower part. The analysis reveals that the total number and length of stream segments confirms the Horton’s law. Calculated Circularity Ratio (Rc) value of 0.27 and value of Elongation Ratio (Re) 0.41 indicates that the basin is elongated in shape, having low discharge of runoff and relatively permeable subsoil condition. The value of Form Factor (Rf), 0.26, represents a flatter peak of flow for longer duration. Flood flows of such elongated basins are easier to manage than of the circular basin. The study further validates that the morphometric analysis based on GIS techniques is quite suitable and competent tool for geo- hydrological studies. These studies are very useful for rain water harvesting and watershed management.
