Geographic Knowledge and Understanding
Increased dam building for multipurpose water schemes, and their cost and benefits. A case study of contemporary dam building expansion in one major drainage basin.
Dam building creates the possibility to harness water for a number of purposes. Multipurpose dams can impact the traditional fluvial processes found within a drainage basin and this can impact the rivers use.
To have knowledge of why there is a need to increased the number of dams found within a drainage basin.
To have an understanding of the benefits and problems created by increased dam building.

Taken From -
You have already explored the issues raised by concerning the building of the Grand Ethiopian Renaissance Dam. You are now going to look at The Nile from a different point of view and see how the increase in dam building is done to allow different stakeholders to flourish. To do this collect a piece of A3 paper and a set of coloured pens and then watch the youtube clips below.
- In one colour give details of five existing dams within The Nile drainage basin. Include their age, location, and purpose (this could be in the form of a map).
- Choose a different colour and pick one specific dam that you consider to be a multipurpose scheme. Name the dam and explain why it is considered to be multipurpose.
- In a different coloured pen write down the costs of the dam. Think SEEP and to whom the dam is a problem for.
- In a fourth colour write down the benefits of the multipurpose dam. Think SEEP and to who the dam benefits.
- In a fifth colour write down the history of the dam and how it has been expanded.
