Abstract
Groundwater is one of the most valuable natural resources. Surprisingly, for a resource that so widely used and so important to the health and to the economy of the country. During the last decade, land reclamation projects extended to the southern and eastern areas of west Nile Delta, depending mainly on surface and groundwater, which represent the sole water source in these areas. Accordingly, new desert settlements are established by the Egyptian government e.g. south El Tahrir, New Ameriya, El Sadat city, El Nubariya and El Bustan as pilot areas, all are aiming for creating new communities in these areas. The continuous development of human society as well as the side effects of land reclamation projects left negative impacts on soil and water resources. Such negative impacts are pronounced in water pollution and soil salinization. Moreover, the enormous groundwater withdrawal leads to continuous groundwater depletion. Soil salinization is mainly attributed to the groundwater quality, irrigation systems, types of fertilizers, and the badness of drainage systems too. Some areas especially adjacent to El Nasr and El Nubaria canals are exposed to water logging and deterioration of the cultivated lands.
