  • Managing flooding
    • Hard engineering
      • embankment (levee)
        • good points
          • stops flood water from spreadig
        • bad points
          • expensive
          • may burst
      • Deepening the channel
        • good points
          • water flows away quickly
        • bad points
          • defers flooding
          • unsightly
      • Dam built upstream
        • good point
          • can regulate water flow
          • bad point
            • can burst
            • Expensive
      • relief channel
        • good point
          • takes over flow water
        • bad points
          • expensive
          • disruptive and complex to build
    • Soft engineering
      • Washland
        • good points
          • cheap
          • water can go somewhere
          • used as a habbitat
      • Plant trees
        • good point
          • trees reduce the amount of water
          • provides habbitats
        • bad point
          • land cannot be used for anything else
      • flood warning system
        • good point
          • prepares people
        • bad point
          • difficult to give enough warning
      • Planning
        • good point
          • building restricted to areas of low risk to flooding
        • bad point
          • may cause planning problems elsewhere
