1.3.1 The opportunities and hazards of living near a river.
The River Nile is the longest river in Africa and has provided opportunities for people for thousands of years. Its water supports farming in the dry deserts of Egypt and Sudan, while also providing drinking water, transport routes and hydroelectric power. The fertile land created by the Nile has allowed settlements, towns and cities to develop along its banks, making it one of the world's most important rivers.
Task 1 - Complete the note taking summary sheet below using the clues around the map and this National Geogaphic article to highlight the opportunities that rivers (such as the Nile) bring to people.
Task 2 - Now watch the video below and make notes on the back of the Task 1 sheet to explain why Egypt is running out of water. Focus in particular on the Grand Ethiopian Renaissance Dam and what this means for Egypt.

Flooding - Causes, Impacts & Management (Baregès - France 2013).
Flooding is one of the most common and destructive natural hazards affecting river environments. It occurs when a river cannot contain all of its water and overflows onto the surrounding land. In June 2013, the River Bastan burst its banks after intense rainfall and rapid snowmelt, causing severe flooding in the mountain village of Baregès in the French Pyrenees. In this section, you will investigate the causes and impacts of this flood and evaluate the different strategies, including sustainable approaches, that have been used to reduce the risk of future flooding.

Your task - The completed detailed specific specific example can be found below by clicking on the worksheet. This pack of work contains the causes, impacts and management strategies associated with the flash flood event in the summer of 2013. This means that you don't have any research to do on this section, however you will be required to answer some Physcial Geography style paper 1 questions based on the content. These questions can be found on the penultimate page of the document, with a guide to answering questions on the last page.
Please see the video below for more information on the management of the River Bastan to protect from further flooding. This news report was from June 2014 - one year after the flood event. This compliments the work in your study pack above.
An Evaluation of Flood Prevention Strategies
|
Flooding only becomes a hazard when it affects people, property or infrastructure. A river overflowing onto its natural floodplain is a normal process. However, when homes, businesses or transport routes are built on the floodplain, flooding can cause significant damage and disruption. Flood risk has increased in many parts of the world for two main human reasons: 1. Urbanisation – Roads, car parks and buildings are covered with concrete and tarmac. These impermeable surfaces prevent infiltration, increasing surface runoff and causing rivers to rise more quickly after heavy rainfall. 2. Building on floodplains – More homes, businesses and infrastructure are being built on land that naturally floods. As a result, more people and property are at risk when rivers burst their banks.

The Causes & Impacts of River Pollution & Management
The River Garonne flows through Toulouse and is one of the most important rivers in southwest France. It provides drinking water, habitats for wildlife and opportunities for recreation. Although the Garonne is considered only moderately polluted, human activities continue to affect water quality. Local organisations are now using innovative and sustainable methods to reduce pollution and protect the river for the future

The background. Before we start our work on our DSE focusing on the river Garonne, please complete the worksheet below looking at the general causes and impacts of river pollution globally.
We are now going to focus our attention on the River Garonne and the causes and impacts of river pollution, as well as the sustainable techniques that are being used to solve this problem in a sustainable way.
Task 1 - Watch both videos above, and if necessary, use the summary documents of the transcript. The first video outlines the problem of river pollution on the Garonne and the second introduces a novel strategy aimed at removing this plastic from the river.
