Abstract: Watershed prioritization has gained importance in natural resources management, especially in the context of watershed management. Watershed management encompasses various activities from watershed delineation to monitoring. The present research attempted to study various morphological characteristics and to implement Remote Sensing and Geographical Information System (GIS) techniques for identification and prioritization of critical sub watersheds situated in region of Ozat river basin, Gujarat. The morphometric analysis of river basin helps to explore the interrelationship between hydraulic parameters and geomorphologic characteristics. Various morphometric parameters, namely linear and shape have been determined for each watersheds and assigned ranks on the basis of value/relationship so as to arrive at a compound value for a final ranking of the watershed. There are in total 4 sub-watersheds which have been delineated and taken up for prioritization based on morphometric analysis using GIS and RS techniques. Detailed morphometric analysis was carried out using ArcGIS V10.1. The value of compound parameter for all 4 watersheds varied from 27 to 32. The watershed 5G1C4 (compound parameter value 27) receives the highest priority value and so it becomes potential and prioritized candidate for applying soil conservation measures, in contrast to the other watersheds with low priorities are subjected to lower degree of erosion. The morphometric properties and prioritization for each watershed will be useful for the sound planning of conservation measures, water harvesting, and groundwater recharge projects on watershed base.
