Impacts Of Floods

  1. 1. Impacts of Floods<br />AS Geography<br />
  2. 2. Plenary<br />In small groups write down what all the human causes of flooding are and all the physical causes are<br />
  3. 3. The Answers<br />Human<br />Urbanisation<br />Deforestation<br />Poor River Management <br />Climate Change<br />Physical<br />Excessive levels of precipitation over a prolonged period<br />Intensive Precipitation over a short period<br />Snowmelt<br />Climatic Hazards <br />Relief<br />Vegetation<br />Geology<br />Soil Type <br />Drainage Density<br />
  4. 4. Learning Objectives<br />Students will understand the difference between short, long term and intangible impacts of flooding<br />What type of responses we have to cope with flooding<br />Begin to appreciate the type of strategies presently used in river management<br />
  5. 5. Activity<br />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<br />Short term<br />Long term<br />Intangible<br />Once you have completed elect one member of the group to take their sheet to another group to explain what you have put.<br />
  6. 6. Short Term Impacts<br />Death<br />Injury<br />Loss of infrastructure<br />Damage to property and business<br />Damage to crops<br />Disease<br />
  7. 7. Long Term Impacts<br />Rebuilding of roads and infrastructure<br />Houses needing demolitioning or rebuilding<br />Uninsured losses<br />Loss of trade and industry<br />Public perception of place<br />Costs of insurance<br />
  8. 8. Intangible Impacts<br />Emotional and psychological damage<br />Sentimental loss of property or items<br />Sleeplessness<br />Nervousness<br />Irritability and tiredness<br />Depression<br />
  9. 9. High Risk Flood Areas in UK<br />
  10. 10. Being Prepared<br />How many different ways are there that you can think of; for being prepared for floods?<br />In an MEDC (Most Economically Developed Country) – UK<br />EA use flood map to find likely flood areas<br />Met office provide key data<br />Computer modelling help with predictions<br />
  11. 11. Environment Agency Warning Levels<br />
  12. 12. What Can We Do?<br />Are you at Risk – Find out the likelihood of your nearest rivers from flooding<br />
  13. 13. What Can We Do?<br />Preparing for flood when warnings are issued<br />Make a flood action plan<br />Get flood protection to protect your home<br />If Necessary GET OUT!<br />Find out more : &gt;&gt;HERE&lt;&lt;<br />
  14. 14. Management Strategies<br />Structural Methods – Protection through Engineering<br />River Basin Management – Seek to reduce the likelihood of flooding<br />Modifying the burden of loss – Insurance schemes<br />Bearing the cost of the flood – ‘Do Nothing Approach’<br />
  15. 15. Management Typescome in two basic forms<br />Hard Engineering<br />Structural<br />Soft Engineering<br />Working with the landscape not against it<br />
  16. 16. Activity<br />Discuss in your groups the different methods of structural engineering you can think of. See if you can think of any examples of these.<br />E.g. - dams<br />
  17. 17. types<br />Flood walls, embankments and levees<br />Channel Improvements<br />Relief Channels<br />Flood Storage Reservoirs<br />Flood Interception Schemes<br />River basin management<br />Flood Abatement<br />Flood Proofing<br />Flood plain Zoning<br />Flood Prediction and Warning<br />
  18. 18. Activity<br />Pages 30 – 34 explain these methods write down a short explanation of each<br />And then give the pro’s and con’s of each on the sheet provided.<br />
