Nile Delta - Case Study P1
Deltas
The delta is a 'Arcuate' delta
Shaped by longshore-drift, which keeps the edges smooth.
The Nile water barley reaches the end of the delta.
Geological processes
Erosion at 100m per year in some places.
Dams, food security, global warming
One of the most fertile tracks of land in the world.
Aswan High Dam stops flooding, which balances coastal erosion.
Erosion increasing due to global warming.
Over 50 million people living around the delta region.
Declared one of the most vulnerable areas to sea level rise, with 1 metre sea level rise drowning 20%.
Water supplies are continually being used up.
70% drop in water volume in the delta due to climate change in the next 50 years.
wheat and maize yields down 40% and 50%. $1,000 lost per hectare.
Continued efforts to irrigate the desert.
Pollution and salinsation
Increasing pollution as Egypt's population grows 20 mil+.
Saltwater intrusion is destroying crops, which traditionally was flushed out by the Nile's seasonal floods, is being prevented by the Aswan Dam.
Irrigation canals continue to bring fresh water to prevent salinsation.
