Abstract:
In this study an integrated approach to identify priority sub-watersheds by using the Sediment Yield Index (SYI) model of the All India Soil and Land Use Survey (AIS&LUS, 1991) has been used in Kotani watershed of Seonath basin, Chhattisgarh. The study watershed is divided into 17 sub-watersheds on the basis of drainage conditions. The SYI values of individual sub- watersheds have been computed and categorized into various classes such as very high, high, medium and low priority classes. The maximum SYI value of 1216.26 was computed in case of sub watershed ‘SW8’whereas minimum value of SYI 827.81 was and in sub watershed ‘SW5’.
