Abstract In many areas, especially the dry ones, groundwater is a freshwater source because of the limited availability or absence of-surface water, which affects groundwater quantity and quality over time. The objective of the current study is to investigate the most suitable zone for recharge groundwater into the West Assiut desert fringes aquifer due to its limited potential. Data were collected from various sources, including satellite images, hydrogeological maps, groundwater depths, and-salinity maps. Landsat OLI 2021 satellite images are used to extract a land use map. Geographic Information System (GIS) software is utilized to generate thematic maps and build the model to explore suitable potential sites to recharge groundwater into the aquifer. According to the importance of each studied factor, classified raster maps were given weights. The most suitable sites were selected as far as possible from the River Nile, urban areas, roads, and agricultural areas. Results revealed that the most suitable sites are located in the Wadi deposits aquifers in the back desert. All selected sites had salinities ranging from 847.5 to 1458.3 ppm and groundwater depths ranging from 19.57 to 68.83 m. It could be concluded that the west Assiut area is a potential area for groundwater recharge as an example of the Middle Upper Egypt development region.
