Aim of the study:
This study presents an integrated framework to assess future flood hazard in the Oued El Maleh watershed (Mascara Province, Algeria) by coupling statistically downscaled CMIP6 climate projections with hydrological modeling using SWAT and HEC-HMS, followed by two-dimensional hydraulic simulations using HEC-RAS 2D. The SWAT model was employed to calibrate and evaluate the basin hydrological response under historical conditions, whereas HEC-HMS was used to generate design-storm hydrographs that served as upstream boundary conditions for HEC-RAS 2D flood inundation simulations.
