What were the effects of the creation of the Lake Nasser Aswan High dam?

Answer 12

Sedimentation causes a reduction in the dam capacity as it builds up at the dam.
Loss of fertility soils downstream due to the lack of silt - meaning artificial fertilisers are used causing chemical pollution.
Erosion of Nile delta meaning that the sediment is no longer reaching the the delta to replace the eroding soils.
Standing water provides breeding ground for paracites.
Reduced water flows down stream lead to higher evaporation rates leaving salinisation and decrease in crop yields.
Fresh water ecosystems invaded by salt water near the delta.

Settlements are located to the right if the Nile due to flat land with good water supply
Citrus and grape farming but only makes 17% of GDP in Eygpt
River ports at Alexandria, Cairo and Luxor
HEP at the Aswan Dam also acts as a flood defence
