The Nile River is the main source of water in Egypt. It provides the country with about the 95 percent of its water requirements. There are about 18.000 irrigation structures controlling the flows through the network, including seven major dams on the Nile. These dams are old, there is an urgent need to rehabilitate or replace the deteriorated ones. Therefore, the water managers who are faced with the problem needed to evaluate few alternatives. Few alternatives are considered. Multi-criteria analysis provides an efficient tool for dealing with such problems. It can accomodate social, economic, environmental as well as technical aspects. An MS/EXCEL program has been developed to solve multi-criteria problem by comparing different feasible alternatives. It uses several MCA techniques and presents the results in simple graphs to show the rank of each alternative. The application of the MCA framework through the develop program proved to be a good aid to the water managers who need to select the best alternative.
