Abstract: A distributed parameter model, AVSWAT (Arc View soil and water Assessment Tool) was calibrated and validated on monthly basis for the upper Betwa Basin. India extraction of river basin characteristics like land use/ land cover, soil map, digital elevation model (DEM), drainage information of the study area using remote sensing, GIS and collateral data. The main objective was to validate the performance of SWAT and the feasibility of using the model as a simulator of runoff processes at a catchment area Berasia, Bhopal, Raisen and Vidisha of upper Betwa basin. All hydrological and meterological data, were collected from Indian water portal. Land use map of the area were collected from National Bureau of Soil Survey and Land Use Planning, Nagpur, Monthly surface runoff for the monsoon months (1993-2002) were collected for Berasia, Bhopal, Raisen and Vidisha. The model was calibrated and validated for the monsoon seasons of 1993-99 and 2000-02 respectively. The performance of the model was evaluated using statistical and graphical methods to decide the capability of the model simulating the runoff of upper Betwa basin. The calibration period reported coefficient of determination R2 of Berasia, Bhopal, Raisen and Vidisha are 0.97, 0.96, 0.94 and 0.98 respectively. The relative error was obtained as 6.68, 8.00, 10.17 and 15.97 respectively. The value of Nash Sutcliffe model efficiency obtained was 0.98, 0.97, 0.99 and 0.93 of Berasia, Bhopal, Raisen and Vidisha respectively. The validation period reported R2 of 0.98, 0.97, 0.95 and 0.76 of Berasia, Bhopal, Raisen and Vidisha respectively. The relative error are 6.77, 10.61, 7.91 and 10.56 respectively. The value of Nash Sutcliffe model efficiency obtained was 0.99, 0.99, 0.95 and 0.99 of Berasia, Bhopal, Raisen and Vidisha for monthly observed and simulated runoff. Calibration and validation results revealed that model was/ predicting total surface runoff, at Berasia, Bhopal, Raisen and Vidisha of Upper Betwa Basin accurately. The calibrated and validated model will be used for both long – term and storm event water quantity and quality evaluations throughout the basin.
