Narrator: Melbourne's landscape is constantly changing.

Together with climate change, we are now seeing more extreme weather events and our flood risk across the city is set to increase.

Flooding isn't always best managed by adding new drains and retarding basins.

The best approach is to understand where floods might occur, so we can raise awareness of flood risk and be better prepared.

That's why Melbourne Water is updating flood maps using new flood modelling for every catchment in Melbourne [Illustration of a flood map with the text “Flood map”], to understand flood risk today and into the future [On screen text: Year 2047 ticking over to 2100]

We understand that floods can be concerning. However, flood maps don't create more risk [Illustration of flood map with the text “Flood map”]. They help us better understand our existing flood risk and what to do in a flood event.

Flood models use historical data and modern technology to simulate the behaviour of storm and flood waters to determine which areas of Melbourne would flood.

[On-screen text: “What are flood maps used for?”]

Flood maps are used to update municipal planning scheme controls to ensure planning and building decisions take flood risk into consideration.

They help inform where upgrades to the drainage system and other mitigation works might be needed.

They also allow us to work with our partners to inform emergency plans and be better prepared to respond to a flood event.

Understanding our flood risk helps build a safe and resilient city to be better prepared for flooding today, tomorrow and for generations to come.
