Thus, this will affect the vertical and horizontal agricultural development programs in Egypt, which requires the need to rationalize the use of water in agriculture. The exit from the narrow and densely populated valley on the two banks of the Nile River to the vastness of the area of the Arab Republic of Egypt is the only way to build the future Egypt, accommodate the growing number of residents and open broad horizons for growth, progress and development, and of course if we look at the various governorates of Egypt, we find that the largest area is The New Valley Governorate, which is located in the southwestern corner of the Arab Republic of Egypt, and shares the international borders with Libya in the west and Sudan in the south. % of the area of the Arab Republic of Egypt, while the population density is estimated at about one person per 2 km2 (2). The New Valley Governorate includes 5 centers: Kharga, Dakhla, Farafra, Balat, and Paris.The problem of the study showed that the New Valley Governorate depends entirely on groundwater in all areas of use, agriculture, industry, drinking, and others.
