Mitigration/Way Forward:The political future is uncertain at the moment given the current tension, but African nations are beginning to contest Egypt/Sudan’s control and rules. There are two possibilities, either there will be a war for the control of the Nile, or Egypt and Sudan will have to relent. The only way the physical effects of the dam can be mitigated is if Egypt will allow for the removal of water upstream for controlled flooding. This will increase land fertility upstream, and allow for irrigation. To preserve the delta, sediments will have to be allowed to flow downstream, or be removed manually.

Human/Political Issues: 1.Egypt/Sudan Claim Control of Nile•Only they can take water out•Substance of river upstream due to irrigation from Aswan Dam2.Conflict•Countries upstream threaten to dam and remove water•Egypt claims this act of war•African country signed treaty with each other to fight against control3.Egypt only allows for dams to be built for electrical power only•NOT for removal\4.Health

Physical Issues:1.Reduced Sediment Load Suspension Down Stream•Coastal erosion of delta•Increased erosion of river down steam•Ecology suffers from lack of nutrients2.Lake Nasser Formed Behind Dam•Sediment load built up in lake•Decrease in capacity•Cost of maintenance and cleaning•Lentic (stagnant) water in river, reduced aeration•Bacteria growth (harmful)•Bilharzia (long term: kidney failure, bladder cancer)•Increased evaporation•Water quality decrease due to low turbidity3.Irrigation•No flooding down stream•Lack of nutrients for ecology/environment•Increased use of fertilizers•Runoff of chemicals•Eutrophication (Algal blooms build up)4.Water Logging and Increase in Soil Salinity•Downstream less fresh water•Pools of water due to over irrigating upstream

Facts:•Built in 1970•Cost: 1 billion dollars•Height: 111 m (364 ft)•Crest Length: 3830 m (12,562 ft)•Volume: 44,300,000 m^3 •Lake Nasser Capacity: 169 billion m^3•Egypt: 1.96 trillion ft^3, Sudan: .1 trillion ft^3•People Relocated: 50,000•Energy: 10 billion kWh•Sediment: 134 million tons/year in Nile•36Q 487566 2650972 (UTM coordinates)•Geologic setting: Adjacent to a rift zone in the red sea, therefore a passive margin.
