Impacts Of Floods - AS Geography

1. Impacts of Floods AS Geography

2. Plenary In small groups write down what all the human causes of flooding are and all the physical causes are

3. The Answers Human Urbanisation Deforestation Poor River Management Climate Change Physical Excessive levels of precipitation over a prolonged period Intensive Precipitation over a short period Snowmelt Climatic Hazards Relief Vegetation Geology Soil Type Drainage Density

4. Learning Objectives Students will understand the difference between short, long term and intangible impacts of flooding What type of responses we have to cope with flooding Begin to appreciate the type of strategies presently used in river management

5. Activity On the large piece of paper and in groups begin to think about the different types of impacts a flood might have and try to separate them into the three groups Short term Long term Intangible Once you have completed elect one member of the group to take their sheet to another group to explain what you have put.

6. Short Term Impacts Death Injury Loss of infrastructure Damage to property and business Damage to crops Disease

7. Long Term Impacts Rebuilding of roads and infrastructure Houses needing demolitioning or rebuilding Uninsured losses Loss of trade and industry Public perception of place Costs of insurance

8. Intangible Impacts Emotional and psychological damage Sentimental loss of property or items Sleeplessness Nervousness Irritability and tiredness Depression

9. High Risk Flood Areas in UK

10. Being Prepared How many different ways are there that you can think of; for being prepared for floods? In an MEDC (Most Economically Developed Country) – UK EA use flood map to find likely flood areas Met office provide key data Computer modelling help with predictions

11. Environment Agency Warning Levels

12. What Can We Do? Are you at Risk – Find out the likelihood of your nearest rivers from flooding

13. What Can We Do? Preparing for flood when warnings are issued Make a flood action plan Get flood protection to protect your home If Necessary GET OUT! Find out more : >>HERE<<

14. Management Strategies Structural Methods – Protection through Engineering River Basin Management – Seek to reduce the likelihood of flooding Modifying the burden of loss – Insurance schemes Bearing the cost of the flood – ‘Do Nothing Approach’

15. Management Typescome in two basic forms Hard Engineering Structural Soft Engineering Working with the landscape not against it

16. Activity Discuss in your groups the different methods of structural engineering you can think of. See if you can think of any examples of these. E.g. - dams

17. types Flood walls, embankments and levees Channel Improvements Relief Channels Flood Storage Reservoirs Flood Interception Schemes River basin management Flood Abatement Flood Proofing Flood plain Zoning Flood Prediction and Warning

18. Activity Pages 30 – 34 explain these methods write down a short explanation of each And then give the pro’s and con’s of each on the sheet provided.
