The impacts of climate change on the NileDelta have been addressed on local and international level as the Nile Delta coastal zones are vulnerable to sealevel rise.The poster presents recent research activities and findings from the CLIMB project in the Nile Delta andcostal zones of Egypt.Lots of field data have been collected such as aquifer geometry data, soil properties data, well data andcontamination sources. All of these data support a coupled modeling approach of the land surface hydrologicalmodel WASIM-ETH and the hydrological model MOD-Flow to simulate and project the future impact translationof climate projections into hydrological impacts. Results confirm intensified threads to water security. Increasingpotential evaporation (in response to increasing temperature) in combination with decreasing water levels in theNile river, reduced precipitation and groundwater recharge and deteriorating groundwater quality, imposes greatchallenges to ensure the supply of drinking water and irrigation.Current irrigation strategies are highly inefficient and must be replaced by new and adapted systems. Basedon the results of the coupled modeling approach, various scenarios can be evaluated. The vision is to develop aroad map for climate change and green economy that maximizes wellbeing of the Egyptian citizens, operates withenvironmental limits, and is capable of adapting to global environmental change.
