Abstract

This article presents an application of SWAT model to simulate and predict the volume of inflow into Peppara dam reservoir. The model was calibrated and validated using SWAT CUP (SWAT-Calibration Uncertainty Programs). The calibration was done from 2004 to 2013 and validation was performed from 2014 to 2018. The coefficient of determination (R²) and Nash Sutcliffe Efficiency (NSE) obtained were 0.77 and 0.69 respectively during calibration stage and 0.79 and 0.74 respectively during validation stage. Model showed good performance during calibration and validation stage. This rainfall runoff can be used for predicting the volume of inflow into the reservoir for various rainfall events and it can help in planning the water distribution to TVM corporation.
