Flood modelling

Joint flood modelling program

We’re updating flood models across the Port Phillip and Westernport catchments in collaboration with councils, as part of the Greater Melbourne Flood Information Program.

To support council staff participating in these flood modelling projects, we ran 4 online training sessions and developed a series of fact sheets. These aim to equip you with the knowledge and skills to fully engage with the projects and effectively use their outputs.

Training session recordings

Sessions covered the following topics:

  • Session 1: Roles and responsibilities in joint projects (12 November 2024)
  • Session 2: Modelling process, including demarcation and flood data filtering techniques (10 December 2024)
  • Session 3: Receiving, storing, accessing and using flood data (4 March 2025)
  • Session 4: How to operationalise flood data (6 May 2025)
