Application of Satellite-Based and Observed Precipitation Datasets for Hydrological Simulation in the Upper Mahi River Basin of Rajasthan, India

Hydrological modeling is an important tool used for basin management and studying the impacts of extreme events in a river basin. In streamflow simulations, precipitation plays essential role hydrological models. Meteorological satellite measurement techniques provide highly accurate rainfall information with high spatial temporal resolution. this analysis, tropical monitoring mission (TRMM) 3B42 V7 products were employed simulating by using soil water assessment (SWAT) model. With India Metrological Department TRMM data, SWAT model can be to predict discharge identify sensitive parameters Mahi The was calibrated 2 years then independently validated comparing observed simulated streamflow. A strong correlation between calibration validation results Paderdibadi station, Nash–Sutcliffe efficiency >0.34 coefficient determination (R2) >0.77. adequately simulate Upper satisfactory R2 value. analysis indicated that useful applications predicting performance sensitivity analysis. addition, data may require correction before its utilization modeling. This study helpful stakeholders managing agricultural, climatic, environmental changes.
