Abstract:

Runoff estimation is a key factor in the design of soil and water conservation structures to prevent land degradation and erosion. In the present study, the Soil and Water Assessment Tool (SWAT) model was used to estimate the runoff in Pindwara watershed situated in the Sirohi district of Rajasthan and spanning over an area of about 1428 km2. Temporal weather data of rainfall and temperature, digital elevation models, soil data, land use land cover imagery was provided to the model as input to estimate runoff at the watershed outlet. The simulations were carried out for a period of 12 years from 2001 to 2012 with initial two years set up as warm-up period. The estimated runoff was compared to the observed runoff for a period of 8 years from 2003 to 2010. SWAT simulated average annual total runoff of 277.57 mm out of which, 174.96 mm of surface runoff, 15.55 mm of lateral flow and 87.06 mm of return flow was generated. The R2 and NSE values of the simulation were 0.465 and 0.402. The model was not found fit for direct field application and required calibration and validation before incorporating it for a watershed-scale application.
