2.4 The river Nile

Slide 1 - Tekstslide

  • Describe the upper, middle & lower courses of the river Nile;
  • Explain the main uses of the river Nile.

Slide 2 - Tekstslide

Confluence (A meeting point of two rivers).
Confluence = A meeting point of two rivers.

Slide 3 - Tekstslide

Confluence of the Negro River and Solimões River, Brazil.
Confluence of the Danube River and Inn River, Germany.

Slide 4 - Tekstslide

The Nile
The Nile is a rain-fed river: All water comes from rainfall.

The discharge downstream depends on the amount of rainfall upstream.

Slide 5 - Tekstslide

Measured from a point on the river towards the source.
Measured from a point on the river towards the mouth.

Slide 6 - Tekstslide

Regime = The fluctuations (differences) in discharge throughout the year.

High during the rainy season. 

Low during the dry season.

Slide 7 - Tekstslide

Aswan High Dam
Less water flowing through the river downstream.
Upstream a lake is formed behind the dam to store the water.

Slide 8 - Tekstslide

The Sudd Wetland in South Sudan is an extremely large and flat piece of land, where water flows slowly.
Because of high temperatures, there is a high rate of  water evaporation = Water that goes from a liquid into a gaseous state.

Slide 9 - Tekstslide

Lower course
  • The gradient decreases;
  • The river becomes wider;
  • Because of the Aswan Dam there are less sediments in the Nile Delta;
  • The Delta is less fertile;
  • Farmers use artificial fertilizers to grow crops.
The Nile delta and the sediment plume are visible from space.

Slide 10 - Tekstslide

The uses of the river Nile
  • Drinking water;
  • Oppurtunity to transport goods;
  • Deposited sediments made the land fertile;
  • They also provided building materials.

The Aswan Dam changed the river:
  • Regulating the discharge;
  • Assisting in flood prevention;
  • Generate hydropower; electricity generated by the flow of water.

Slide 11 - Tekstslide

Slide 12 - Video

Areas of soil are flooded to provide soil for agriculture.
Using the river for cleaning and fishing in South Sudan.

Slide 13 - Tekstslide

The population distribution is very uneven; places with a lot of available surface water are densely populated.
