This study focuses on flood risk assessment in the Al Hoceima region, utilizing advanced modeling tools such as IBER and HEC-HMS to develop comprehensive flood maps. A detailed digital terrain model (DTM) was processed alongside land use classifications derived from high-resolution satellite imagery, which identified five key land use categories: built-up areas, dense vegetation, forests, infrastructure, and transitional zones. The hydrological simulation revealed varying flood discharge characteristics across three watersheds, with maximum flow rates reaching 80 m³/s in highly urbanized areas. Flood maps classified regions into low, medium, and high-risk categories based on water depth and flow velocity, highlighting significant vulnerabilities in densely populated sectors. The results indicate that 75% of flood events occurred between November and February, aligning with peak precipitation periods. Suggested actions include enhancing drainage infrastructure, regulating urban development in high-risk zones, and implementing community awareness programs. Overall, this research provides vital insights for effective flood risk management, aiding local authorities in making informed decisions to safeguard the population and infrastructure.
