Investigation of sediment load, runoff, and evapotranspiration in watersheds is necessary for efficient use of soil, water resources, and design of appropriate management options. In this study, we used a SWAT model in Soltani basin at Baft to simulate runoff, actual evapotranspiration, and sediment load for two management scenarios during 1979 to 2012. The simulation results were evaluated using NS, R2 and BR2. For the calibration step, we obtained (0.74, 0.77,  and 0.68) for runoff; (0.78, 0.81, and 0.69) for actual evapotranspiration; and (0.75, 0.73, and 0.66) for sediment load, respectively. The results indicated that, all three parameters were simulated quite well in calibration step. In validation step, were obtained (0.71, 0.7, and 0.59) for runoff; (0.74, 0.72, and 0.62) for actual evapotranspiration; and (0.68, 0.69, and 0.56) for sediment load, respectively. This again indicated a good performance of SWAT model. Two scenarios of landuse change and filter strips in the river banks, led to 7% and 38% reduction in sediment load, respectively.
