meeting the needs of the present without compromising the ability of future generations to meet their own needs

use of artificial structures and technologies to control natural processes, such as flooding or river erosion

uses natural processes and landscape features to reduce the risk of flooding and erosion

Costs and benefits of managing flood risk

Geography

Changes in river landscapes along the course of a river

River processes of erosion, transportation and deposition

River landforms caused by erosion and deposition

Interaction of human and physical factors in river landscapes

The storm hydrograph

Factors affecting flood risk

Example of a river flood: River Eden, Cumbria (2015)

Using GIS to analyse river catchments and profiles

This unit teaches pupils about river processes and landforms. Pupils will learn about the physical processes operating in rivers and about the formation of distinctive landforms of river erosion and deposition. Pupils will also learn about the importance and options of river management.

River landscapes

Using structures like dams and embankments to control flooding

Which of the following is a soft engineering strategy?

It can be expensive and unsustainable long-term

Which of these is a potential disadvantage of hard engineering?

To choose the most effective and sustainable option

Because flood risk is the same everywhere

So that only the cheapest strategy is used

Why is it important to evaluate both costs and benefits of flood management strategies?

The continuous movement of water between the sea, air and land

Which landform is most likely to be found in the upper course of a river?

Which process involves the river wearing away its bed and banks?

When a river drops material it was carrying

Which landform is formed by both erosion and deposition?

In which course of the river would you typically find levees?

Costs and benefits of managing flood risk
