Part of the The Handbook of Environmental Chemistry book series HEC, volume 75 Abstract Drainage is the removal of excess water and salt from the soil at a rate which will maintain soil structure and aeration in order to permit normal plant growth. Several studies have indicated that water-logging and salinity problems arise as a result of poor water management and inadequate water table control in irrigated agriculture. At the turn of the nineteenth century, perennial irrigation was introduced in the Nile River Delta and Valley of Egypt. The natural drainage in many areas is not enough to account for the excess irrigation water. This has led to a raise in the groundwater table, and increases problems of water-logging and salinity. These problems have serious effects on crop production in arid and semi-arid regions.
