1 El-Falaky, A. M.; Scott, V. H. 1984. Water quality of the irrigation canals, drains and groundwater in El-Minya, El-Mansuriya and El-Sheikh project sites. Cairo: Egypt Water Use and Management Project. vii, 120p. (EWUP project technical report no.62)
(Location: IWMI-HQ Call no: 631.7.6.3 G232 ELF Record No: H041)
A water quality monitoring analysis for the canals, drains and shallow groundwater in the three Project sites (i.e. Abyuha in El-Minya Governorate, El-Hammami and Beni Magdul in El-Mansuriya, Giza Governorate, and Abu Rayain Kafr El-Skeikh Governorate) was carried but during the period from March1982 to February 1983, for the purpose of studying quality changes with time, assessing the suitability of water for irrigation and providing a critically needed information for the conjunctive water use. The approach taken to evaluate water quality was based on "Guidelines" which indicate thepotential of irrigation water. However, the true suitability of a given water for irrigation depends on the management capability of the water user and the specific conditions of use. The chemical analysis showed that canal water is of good quality for irrigation purposes throughout the whole year. The water quality deteriorated while passing through the soil. The salinity and sodicity of the shallow groundwater were 3 to 7 times greater than those of canal water, indicating that the water is moderately saline and highly alkaline. On the other hand, the quality of drainage water varied widely from time to time during the year and also with the location on the drain section. On the average, the drainage water in Mansuriya area falls in the category of "causing increasing salinity and sodicity problems" when used in irrigation. In Kafr El-Sheikh, the drainage water could be classified as moderately saline and highly alkaline throughout most of the year except during winter closure where it increased appreciably to a degree which might cause a severe sodicity problem.
