Abstract: The hydrological modelling can be done in a better way through semi-distributed approach. The objective of this study is to simulate streamflow for lower Mahi basin, Gujarat, India using a semi distributed SWAT model. Geospatial techniques are essential tools in hydrological modelling. Geographic Information System (GIS) and Remote Sensing (RS) are used for the preparation of spatially varied input thematic layer (e. g. : land use map, soil map, slope map etc. ). The developed streamflow model was calibrated and validated using semi -automated SUFI 2 calibration technique in SWAT-CUP program. Coefficient of determination (R2) and Nash Sutcliffe efficiency (NSE) were used as model performance indicators for the calibration and validation of the developed streamflow model. The results of the model performance indicators show good performance of the developed model. It can be concluded that SWAT model perform well for the simulation of streamflow
