TO DELINIATE AND OBTAIN LAND USE AND LAND COVER MAP USING SWAT MODEL IN SALEBHATA CATCHMENT OF MAHANADI BASIN

Abstract

S everal empirical methods and model are available to simulate the hydrological behaviour of a watershed are the more assumptive manner than the actual field value. Generally, the Geographical Information System (ArcGIS) is employed to investigate the most reliable field data along with topographic futures for watershed management and planning. In the present study physical based, semi-distributed river basin scale Soil and Water Assessment Tool (SWAT) model interface with Geographical Information System (ArcGIS) tool was used to simulate the runoff, sediment yield and to understand the sensitivity of model input parameters in Salebhata catchment area Mahanadi river basin (4,588.9 km 2 ) Odisha, India. The study was conducted to delineate and find out the land use and land cover map of the Saliveta watershed under Mahanadi basin.
