Why are there so many 100-year floods?

Written By Ian Warren

Why are there so many 1-in-100 Year Floods?

  • How the rainfall changes during the storm

  • Size of water catchment

  • Shape of the land

  • Position of your house in the catchment

With so many independent factors, each square metre of your city has a unique 1-in-100-year flood flow.

Climate modeling predicts storm frequency and intensity are likely to increase, but be careful not to let journalists trick you into believing your house will flood every second year.
