Abstract
The SIWARE model package, which stands for SImulation of Water management in the Arab Republic of Egypt, has been developed as a decision support system for the Irrigation, Planning, and Research Sectors within the Ministry of Public Works and Water Resources.
Several scenarios have been simulated for the Nile Delta. In the Eastern Delta it appeared that reducing the allocation duties for the rice crop, rather than substituting the area with maize, is a better alternative to conserve water. Simulations for the Middle Delta showed that the total water supply could be safely reduced by some 10 to 15%, in combination with the introduct ion of spatial varied crop water duties. Finally, it has been indicated that for the Western Delta additional desert reclamation up to some 70,000 ha is economically viable with the present water resources and higher return flows ofdrainage water. A further extension, however, is not recommended without making more water available.
