The Nile was also an important part of ancient Egyptian spiritual life. In the Ancient Egyptian religion, Hapi was the god of the Nile and the annual flooding of it. Both he and the pharaoh were thought to control the flooding. The annual flooding of the Nile occasionally was said to be the Arrival of Hapi. [3]
The reservoir storage capacity is 162 km 3, including 31 km 3 dead storage at the bottom of the lake below 147 m (482 ft) above sea level, 90 km 3 live storage, and 41 km 3 of storage for high flood waters above 175 m (574 ft) above sea level. The annual sediment load of the Nile is about 134 million tons.
The Zanclean flood caused a major change in the environment of the Mediterranean basin; the continental "Lago Mare" facies was replaced by Zanclean deep sea deposits. [7] The flood may have affected global climate, considering that the much smaller flood triggered when Lake Agassiz drained did result in a cold period. [50]
The Nile Basin Initiative (NBI) has been in existence since 1999, with the aim of strengthening cooperation in sharing its resources concerned. [2] The drainage area of the basin covers Burundi, Chad, the Democratic Republic of the Congo, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, the Sudan, Tanzania, and Uganda. The Basin is the ...
The concept calls for excavating a large canal or tunnel of about 55 to 100 kilometres (34 to 62 mi), depending on the route chosen to the Mediterranean Sea, to bring seawater into the area. [2] An alternative would be a 320 kilometre (200 mile) pipeline north-east to the freshwater Nile River south of Rosetta.
Flash floods can cause rapid soil erosion. [14] Much of the Nile delta sedimentation may come from flash flooding in the desert areas that drain into the Nile River. [15] However, flash floods of short duration produce relatively little bedrock erosion or channel widening, having their greatest impact from sedimentation on the floodplain. [16]
The Sahara Sea was the name of a hypothetical macro-engineering project which proposed flooding endorheic basins in the Sahara with waters from the Atlantic Ocean or Mediterranean Sea. The goal of this unrealised project was to create an inland sea that would cover the substantial areas of the Sahara which lie below sea level , bringing humid ...
The dam has a length of about 9 kilometres (5.6 mi) and a crest height of up to 67 metres (220 ft). It consists of concrete-faced rockfill dams on each river bank (the right bank dam is the largest part of the project, 4.3 km long and 53m high; the left bank is 1590 metres long and 50 metres high), an 883-metre (2,897 ft)-long 67-metre (220 ft)-high earth-core rockfill dam (the 'main dam') in ...
