Flood prevention and mitigation strategies can be facilitated by flood susceptibility mapping (FSM), since it signifies regions with the greatest risk according to physical attributes. Therefore, the current work aims to evaluate the susceptibility to flood hazards in the Abu Safaa watershed. For locating and evaluating possible hazardous zones, nine criteria, namely elevation, slope, flow accumulation, rainfall intensity, distance from drainage, drainage network density, TWI, LULC, and NDVI, were integrated into ArcGIS. A mathematical method for modeling flood hazards and providing decision assistance that considers the weighting and ranking for each flood criteria is called the analytical hierarchy process (AHP), which is used to obtain the Flood Hazard Index (FHI), flash flood hazard zones (FFHs), and then generate a flood susceptibility map. Five assessments of flood potential are detected, ranging from extremely low to very high: 11.21% (very low), 26.5% (low), 32.81% (moderate), 20.18% (high), and 9.3% (very high). For flood mitigation purposes, FSM and the selected morphometric parameter results were used to conduct a weighted spatial probability model to figure out probable regions for capturing rainwater, as well as the proposed strategy with suitable locations of water harvesting structures for direct usage as surface water storage, indirect usage as groundwater recharge, or a combination of both. The present study's findings show that the Abu Safaa basin accepted 61.4 × 106 m3 of rainfall in February 2018, which led to a water harvesting potential of about 10.3 × 106 m3 and total losses of about 51.1 × 106 m3

Within the framework of the development activities that the country is keen on in the new urban communities through the state’s cooperation with international organizations such as the FAO (Food and agricultural organization) and the WFP (World Food Program) . In addition it contributes the investment entities with the aim of providing the infrastructure and life necessities of digging water wells and paving roads and public facilities that contribute to the success of the new urban communities. One of these areas is the study area, where a group of production wells were drilled for development activities. With the presence of the Nubian sandstone aquifer, they depend on its feeding on rainwater that falls on the detectors of the Nubian sandstone aquifer and cracked base rocks in addition to the surface runoff of torrential water in this Wadi. Therefore, the management of surface and groundwater resources plays an outstanding role in sustainable development projects in the study area. The greatest benefit from rainwater harvesting techniques from torrents plays a great role in feeding the aquifers through studying the relationship of rainfall and surface runoff with the aim of determining the volume of surface runoff, maximum discharge, and the time of arrival to the maximum discharge. This done by making a hydrograph of flow for Wadi Hodein. On the other hand, the assessment of the productivity of the shallow Quaternary aquifer and how to benefit from it in the development project plays a role in the success of this project through operating wells in a proper scientific manner. Furthermore, the research team carried out pumping and step drawdown tests for existing wells to assess the aquifer potentiality and the productivity to suggest the operating program for those wells.
