From the previously mentioned studies related to the use of RS and GIS in groundwater mapping, it could be concluded thatgroundwater mapping is one of the main tools for efficient and controlled development of groundwater resources. These maps are used by engineers, planners and decision makers to allocate, develop and manage groundwater within a national water policy. Integrated RS and GIS techniques prove to be rather satisfactory options for groundwater mapping in different regions of Egypt.
