Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
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.
Lesson Summary
You will learn to assess the costs and benefits associated with hard and soft engineering strategies aimed at reducing river flooding.
Key Notes
- There are costs and benefits of management strategies to reduce river flooding.
- Hard engineering strategies include flood walls, embankments and flood barriers.
- Soft engineering strategies include flood plain retention and river restoration.
Vocabulary To Learn
- sustainable: meeting the needs of the present without compromising the ability of future generations to meet their own needs
- hard engineering: use of artificial structures and technologies to control natural processes, such as flooding or river erosion
- soft engineering: uses natural processes and landscape features to reduce the risk of flooding and erosion
Common Mistakes To Avoid
- Hard engineering is always better than soft engineering.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
There are costs and benefits of management strategies to reduce river flooding. Hard engineering strategies include flood walls, embankments and flood barriers.
2. Define this geography term and use it in an example. 'sustainable'
meeting the needs of the present without compromising the ability of future generations to meet their own needs.
3. Correct this common geography misunderstanding.
Mistake: Hard engineering is always better than soft engineering. Correction: While hard engineering can be effective, it is not always the best choice due to cost and environmental impact. Soft engineering can be more sustainable and less intrusive.
