The statistical indicators prove the accuracy of PCSWMM for rural catchments. The Nash-Sutcliffe efficiency (NSE), coefficient of determination (R 2), and relative error (RE) values were found between 0.75-0.97, 0.94-0.98, and −0.22-−0.09 respectively. The calibration of the PCSWMM is performed using the sensitivity-based radio tuning calibration (SRTC) tool. The method leverages remote sensing and GIS derive estimates of measured and inferred parameters of Vidor rural catchment to quantify the flash flood events of the last four years: 2014-2017. This study aims to monitor the flash flood response of Vidor/Wadore hill torrent in Pakistan by the integration of Personal Computer Storm Water Management Model PCSWMM (hydrologic) and HEC-RAS 5.x (hydraulic) models.
