Abstract: Flood hazard assessment and mapping is challenging in semi-arid ungauged basins because of the lack of data, the rapid runoff response, climatic variability, and the difficulties of modelling hydraulic processes, such as on piedmont alluvial fans. This study combines hydrological and hydraulic modelling with hydro-geomorphic knowledge gathered during post-flood campaigns in order to determine realistic flood hazard scenarios for a piedmont urban area in Morocco. Partial calibration of the hydrological and hydraulic models is performed using field-estimated peak discharge values and mapped flood extents for known flood events. The calibrated models are then applied to lower frequency–higher magnitude flood scenarios. Finally, a flood hazard map is designed using the Swiss hazard assessment and mapping procedures.
