Development of the SIWARE model package started in Egypt in 1984 as one of the core activities under the "Reuse of Drainage Water Project". Egypt's water resources are almost exclusively limited to the river Nile discharge and reusing drainage water offers a good alternative to increase water use efficiency. Because of the complexity of the irrigation and drainage systems, as well as the interaction at various levels between the systems, only physical modelling provides sufficiently accurate information for evaluating water management scenarios. The "SImulation of Water management in the Arab Republic of Egypt" package offers such an advanced modelling tool.
Between 1990 and 1995, various water management scenarios have been simulated for the complete Nile Delta. These scenarios are extensively documented in Reuse Report 30 "Analysis of Water Management in the Eastern Nile Delta", by DRI, Cairo and SC-DLO, Wageningen and in Reuse Report 50: “ Reuse of Drainage Water in the Nile Delta: Monitoring, Modelling and Analysis”, by DRI, Cairo and SC-DLO, Wageningen.
The SIWARE model was again used to support the development of the National Water Resources during the period between 2000 and 2005 (MWRI, Water for the Future, National Water Resources Plan 2017 (NWRP2017), Cairo, January 2005)
Recently an analysis of effects of possible future water shortage on soil salinity and crop yields in the Nile Delta due to climate change and upstream developments in the Nile river was made: Smit, R, M.
