Low-Energy (Nile Delta)

Cards (10)

  • 150km long bordering Mediterranean Sea
  • Sediment load 30% clay, 40% silt and 30% sand
  • Limestone outcrops experience carbonation
  • Clay less resistant to erosion so sediment more easily formed, which a delta needs
  • Arcuate so sediment is coarse-grained
  • Average sediment yield is 4.26 t / ha / yr
  • Imbalance between erosion and accretion since Aswan High Dam was built in 1964
  • Sediment accreted from 120 million tonnes to trace amounts
  • Increase in erosion to the NW of the delta
  • Coast retreats at a rate of 148 m / yr due to Med sea level rising 1.2 mm / yr
