Rivers facts in the Western Desert of Egypt? Are there rivers under the Western Desert in Egypt that can be exploited Rivers facts in the Western Desert of Egypt? Are there rivers under the Western Desert in Egypt that can be exploited Are there really rivers in the Western Desert in Egypt? What is the truth about the existence of rivers under the Western Desert in Egypt? Groundwater resources are considered one of the non-traditional water resources that are characterized by their geographical spread in the Arab Republic of Egypt, mainly in the following four regions: Nile Valley and Delta: It includes the area between the entry of the Nile into Egypt and the Mediterranean, including the Fayoum depression and Lake Nasser. Western Desert: It includes the area between the Nile River in the east, the Libyan borders in the west, the Egyptian-Sudanese borders in the south, and the Mediterranean Sea in the north. Eastern Desert: It is the area between the Nile Valley in Upper Egypt and the Red Sea. Sinai Peninsula: The first region depends mainly on the traditional Nile water, on which most of the development activities of drinking, agriculture and industry are based, in addition to its use of other non-traditional water sources such as agricultural drainage water in drain networks or groundwater that is stored in the sedimentary formations reservoir as a result of the leakage of surplus irrigation water Nile, treated wastewater in addition to rainwater in the northern part of the delta. The rest of the regions of the Republic depend mainly on non-renewable groundwater sources, in addition to rain falling on coastal areas. Where the renewable groundwater reservoirs are distributed between the Nile Valley and the Delta region. This water is considered part of the Nile water resources. It is estimated that 6.5 billion m3 of water has been withdrawn from these reservoirs since 2006. This is considered within the limits of the safe withdrawal, which reaches a maximum of about 7.5 billion cubic meters, according to the estimates of the Groundwater Research Institute. It is also characterized by a good quality of water, with salinity reaching about 300-800 parts per million in the southern delta regions. It is not allowed to drain the water of these reservoirs only when drought occurs for a long period of time, so this water is considered of an important strategic value. It is estimated that withdrawals from these reservoirs will reach about 7.5 billion m3 after 2017. As for the non-renewable aquifers, they extend under the eastern and western deserts and the Sinai Peninsula. The most important of which is the Nubian sandstone reservoir in the Western Desert, whose stock is estimated at about 40 thousand billion m3, as it extends in the Northeast African region and includes the lands of Egypt, Sudan, Libya and Chad. Great depths, which causes a rise in the costs of lifting and pumping. Therefore, what was withdrawn from that water is about 0.6 billion m3 / year, which is sufficient to irrigate about 150 thousand feddans in the Al-Owainat area. It is expected that the annual withdrawal rate will increase to about 2.5-3 billion m3 / year as a safe and economic withdrawal. In general, the effects resulting from the expected decrease in the level of the aquifer must be avoided, by switching from the system of cultivating large areas to the system of farms specified in separate areas (2000 - 5000 acres) in order to preserve the underground tanks for long periods. We hear a lot about the discovery of rivers buried in the desert. How true is that?
