Flood Mitigation in the Transboundary Chenab River Basin: A Basin-Wise Approach from Flood Forecasting to Management

Rapid and reliable flood information is crucial for minimizing post-event catastrophes in the complex river basins of world. The Chenab River basin one world, facing adverse hydrometeorological conditions with unpredictable hydrologic response. Resultantly, many vicinities along undergo destructive inundation, resulting huge life economic losses. In this study, Hydrologic Engineering Centre–Hydrologic Modeling System (HEC-HMS) HEC–River Analysis (HEC-RAS) models were used forecasting inundation modeling basin. HEC-HMS model was peak flow simulation 2014 event using Global Precipitation Mission (GMP) Integrated Multisatellite Retrievals-Final (IMERG-F), Tropical Rainfall Measuring Mission_Real Time (TRMM_3B42RT), Satellite Mapping Precipitation_Near Real (GSMaP_NRT) precipitation products. calibration validation HEC-RAS carried out events 1992 2014, respectively. comparison observed simulated at outlet indicated that IMERG-F has good results. extent revealed an overall accuracy more than 90% when compared satellite imagery. performed well Manning’s n 0.06 floodplain. From results, it can be concluded remote sensing integrated could workable solutions forecasting, modeling, early warning. concept management (IFM) also been translated into practical implementation joint Indo-Pak mitigation transboundary
