Flooding risk assessment clearly shows the urgent need for an evaluation planning program to mitigate hazards for vital areas. Because of the rising urbanization and climate change, flood risk management has gained importance. to implement methods and policies for urban development that are sustainable. In recent decades, studies on the management of flood risk and spatial planning have shown that there is a shared understanding of the notion of flood resilience in the formulation of policies and strategies. A number of governmental and investment initiatives, including those related to industry and tourism, have recently been launched in the Wadi Ghoweiba coastline zone. The drainage network of Wadi Ghoweiba is made up of long, wide channels with steep sides and a floor that is highly inclined. Due to these characteristics, there is a good chance that significant volumes of rainfall may fall and cause damaging flash floods into the Gulf. Delineating drainage networks is essential to predict surface water runoff and consequently the flash flood hazards. Wadi Ghoweiba networks and sub-basins are studied here to compute its morphological and hydrological parameters as to assess their risk degree and classify their relative vulnerability. Using the calculated morphological and hydrological data, the investigated watershed is ranked in order of flood risk as part of the flood risk assessment technique. This research uses DEM data in GIS-Environment to analyze Wadi Ghoweiba's flooding risk. According to the ranking hazard and El-Shami method, two sub-basins are High of flooding hazard, one sub-basin of very high hazard, and two of extremely hazard. Therefore, we recommend that decision-makers build some dams downstream of sub-basins that have a high hazard degree to reduce the risk of flooding or create artificial lakes to receive rainfall water and for sustainable development in the present and future, especially in the promising areas like Wadi Ghoweiba basin. Our findings can be a potential guide to decision-makers in disaster geohazard reduction.
