Abstract

A Drainage basin or watershed is an area of land where surface water from rain, snow, ice converges to a single point at a lower elevation usually the exit of the basin, where the water join another water body, such as a river, lake, reservoir, estuary, wetland, sea or ocean. Morphometry is the measurement and mathematical analysis of the configuration of the earth’s surface, shape and dimension of its landforms. Morphometrical analysis of a drainage basin provides quantitative description of the drainage system. Dindigul is inland district with an extensive hilly and rocky areas and the according to the recent studies ground water in this region is heavily exploited for domestic, agriculture and industrial purpose. Kodavanar is a major river flowing in the district, Using geospatial tools such as Remote Sensing and GIS for extraction of Kodavanar watershed. The data from Shuttle Radar Topography Mission is used for drainage morphometry and evaluating various morphometric parameters such as linear, areal and relief parameters. These parameters were analysed used Analytical Hierarchical Process(AHP) and sub watersheds were ranked. This study will be helpful for effective management of Kodavanar watershed.
