  1. The River Nile

  2. The Impacts of the Aswan Dam on the River Nile • What environmental effects has the Aswan Dam had on the Nile Drainage Basin? • What socio-economic effects has the Aswan Dam had on the people of Egypt?

  3. What is the Aswan Dam? • Constructed in 1971 • Regulates the flow of the River Nile • Lake Nasser was created as a result of the Dam • Lake Nasser stretches over a distance of more than 312 miles

  4. Why did Egypt need a Dam? • The River Nile regularly flooded and destroyed crops • Irrigation • HEP • Navigation

  5. What are the implications of the Dam? • Agriculture • Fishing • Delta • Water Loss • Ecosystems

  6. Agriculture • No sediment deposition • Fertiliser • Loss of Land

  7. Fishing • Average fish stocks have declined from 35,000 tonnes in 1962 to approx. 9000 tonnes after the Dam was constructed • Lake Nasser is silting up

  8. Delta • Fertile land of the Delta is eroding a rapid rate • The Delta is the most fertile part of Egypt • Silt is no longer reaching the Delta

  9. Water Loss • Egyptian evaporation rates have dramatically increased • Lake Nasser loses 10-16 billion cubic meters of water every year through evaporation • This volume of evaporation is approx. 20-30% of Egypts Nile Water
