Abstract
Om Lashtan village is part of the Egyptian North coast that has numerous natural resources. This paves the way for development growth in the region; however, development efforts are still modest and not commensurate with the richness and capabilities of the region. Besides rainfall is the source of fresh water in the city, it also forms the main reason for flash flood occurrence that causes serious disasters and huge losses. In November 2020, one of the extreme weather events caused great harms on the different activities and development projects in the city. The main aim of the paper is to propose methods to mitigate the risks of flash flood events in Om Lashtan village considering its rural communities and poor infrastructure. First, the Om Lashtan wadi was specified as the active hydrological wadi that threatens the village located near the outlet. Then, the water volumes and peak discharges were estimated from modeling the extreme flash flood event, which occurs during the storm in November 2020. Furthermore, some measures were investigated to mitigate flood risk and the possibility of selecting the suitable one to protect the village and harvesting storm water. Consequently, the outcome from this paper would help decision-makers in their future development plans in Om Lashtan City. In addition, the harvested storm water would promote various activities such as cultivation, grazing and creating the appropriate climate for the implementation of development plans in the area.
