Transcript

  • 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!

  • 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.
