Environmental Agency: Adaptation to Coastal Change
Secondary | Environment | Views: 288
- Name the two types of coast and their distinguishing features. How are they managed and why?
- Low lying coastline is more susceptible to flooding – how are these floods caused?
- Wave damage is the most dangerous of flooding types, how are these caused and what can be done for safety?
- The video focuses on the incidences of wave damage flooding over time, what damages were caused? Think about these incidences and how it illustrates the progression of response from the Environmental Agency.
- How is coastal erosion predicted? What factors affect the rate in which the coast erodes?
- What is hydraulic action? How does it happen?
- Kellie demonstrates abrasion, attrition and solution using tennis balls. Use Kellie’s demonstration to create a labelled diagram of each process.
- Guy uses the same two tennis balls to illustrate longshore drift and transport processes. Draw labelled diagrams of the process of saltation, fraction and suspension.
- What happens when grains from erosion are transported to a low energy area? Describe it.
- How is the sea level predicted to rise by the year 2100? How are the Environmental Agency planning for this adaptation? What environmental factors contribute to rises in sea levels?
- Flood Technology has improved detection, forecasting and warning of floods – can you name and describe these advances?
- Many adaptations have been made over time to deal with coastal erosion – describe these progressions.
- Working with natural processes can also help build defences against flooding. Explain how these are less impactful on the environment.
- Relocation is an unfortunate consequence of coastal erosion. Rollback is an alternative. The Environmental Agency tries to do this in an anticipatory way. Imagine the effects of this on homes and families, however also imagine the alternative.
- Another option is to make a house more flood resilient. Imagine your home is located in a high-risk area. What changes can you make to make coping with flooding easier?
- Coastal defences prevent flooding reaching the land – can you name these? Why are they designed the way they are? Beach recycling also helps preserve these, why is this a good choice?
- Guy demonstrates a Wave Tank to show how defences work, this helps us envisage the design features and why they were engineered in such a way. Use these demonstrations to draw labelled diagrams of each defence type and explain its effectiveness.
