Egypt is a country of tremendous land resources but limited water
resources The area of cultivated land is only 3.2 per cent of the
gross area. The river Nile is the main sources of water. In the
recent years the Governement established large-scale agricultural
projects in light of food security related to the population
growth. Expansion of irrigated agriculture has to be predomantly
relalized bt increasing the water use efficiency. In Egypt, the
dominant irrigation method is surface irrigation, which covers
approximately 83 per cent of the irrigated areas. Surface
irrigation or gravity methods are generally characterized by a low
efficiency. One opportunity to increase the efficiency is to
convert surface irrigation to modern irrigation systems, which are
generaly highly expensive for a country like Egypt. Another option
to increase the efficiency of surface irrigation systems is to
convert the traditional irrigation method based on continuous flow
to surge flow irrigation. Surge flow irrigation is the intermittent
application of water to furrows in a series of relatively short on
and off time periods.
