“…The problem of lack of sufficient water for agricultural lands is increasing in many regions of the country. Thus, floodwater harvesting is a good solution for reducing flood risk and water scarcity in arid and semi-arid regions [2]. We can say that floodwater is the main source of surface water and groundwater for many arid and semi-arid regions [3] because it is needed to control and manage floodwater for later use.…”

Climate change and population growth are the important factors that place additional pressures on water resources, and generally, predictions indicate that these pressures are increasing continuously, so it is necessary to regulate surface water sources. Afghanistan has a semiarid climate and already received worse effects of climate change; therefore, there is an extremely needed regulation of river flow across the country. Arghastan River is in the southernwest parts of the country, thousands of cubic kilometers of water in this river are wasted annually, and drought and floods are the main problems of the residents due to nonmanagement of river flow. The main objective of the study conducted by GIS was to find a dam site along the river for proper water management. A contour map was created for the entire watershed by using 5-meter DEM, that the most suitable site for the dam is at the coordinate of 66°48'34.468"E 31°35'4.512"N, it is possible to build up to 170-meter-high dam. The purpose site of the reservoir has the capacity to store about 1700 million cubic meters of water at an elevation of 170 meters, while the average monthly discharge of the Arghastan River up to the specific point of the investigation is about 38.6 m3/s. Suppose the floodwater of this River basin is harvested. In that case, it will provide the chance for residents to rescue their property from flood hazards during the rainy season, and they will have enough water for irrigation purposes during the summer season.

“…Moreover, a heavy rainfall event in October 2016 led to the loss of tens of people lives in Ras Gharib city, situated in the Red Sea Governorate (Moawad et al 2016;Elnazer et al 2017). The Red Sea coast region is currently experiencing an increasing trend in the frequency, severity, and impacts of heavy rainfall and flash flood events (Almasalmeh and Eizeldin 2020;Arnous et al 2022). These severe flash floods pose significant threats to local communities, industrial facilities, and the tourism industry in the Red Sea region (Elnazer et al 2017).…”

Flash floods are a major threat to life and properties in arid regions. In recent decades, Egypt has experienced severe flash floods that have caused significant damage across the country, including the Red Sea region. The aim of this study is to map the flood hazards in flood-prone areas along the Red Sea region using a Geographic Information System (GIS)-based morphometric analysis approach. To evaluate the flood hazard degree, the adopted methodology considers various morphometric parameters such as basin area, slope, sinuosity index, shape factor, drainage intensity, circularity ratio, and curve number. GIS techniques were employed to delineate the watershed and the drainage network. The delineated watershed was used together with the digitized maps of soil and land use types to estimate the curve number and the morphometric parameters for each subbasin. The flood hazard degrees are calculated based on the considered morphometric parameters and distinguished based on a five-degree scale ranging from very low to very high. Results indicate that 47% of the study area has a very high flood hazard degree. Furthermore, morphometric analysis results align with the runoff results simulated by a hydrological model, where, for example, basins with a high to very high hazard degree exhibited high runoff. This suggests the influence of physical characteristics on the hydrological behavior of the watershed and further validates the morphometric analysis presented in this work. The results presented here can help policy planners and decision-makers develop appropriate measures to mitigate flash floods and achieve sustainable development in arid regions.
