The record-breaking floods in north Queensland are a stark reminder of the increasing frequency and severity of extreme weather events across Australia. From bushfires to floods, our water systems face complex challenges that require careful planning, response, and recovery strategies.

Water Research Australia (WaterRA) has long been committed to supporting the water sector in preparing for and managing these events. In 2022, we hosted a webinar series on keeping the water on during and after extreme events, featuring firsthand insights from industry professionals who had navigated crises including flooding, bushfires, and drought.

The flooding-focused session provided valuable perspectives from:
๐Ÿ”น Dr Alison Oke (Bureau of Meteorology) โ€“ Extreme rainfall and runoff trends in Australia
๐Ÿ”น Asm Mohiuddin (Sydney Water) โ€“ Water quality impacts of floods in Warragamba Dam
๐Ÿ”น Michael Harrison (Icon Water) โ€“ Icon Waterโ€™s flood response (2019โ€“21)
๐Ÿ”น Brian Hester (Seqwater) โ€“ Lessons from Ex-Tropical Cyclone Oswald (2013)

These insights remain as relevant as ever. The full webinar series is now available to members and non-members, providing a vital resource for those working to safeguard water supply in extreme conditions.

Research-driven solutions for extreme events

WaterRA members also have access to research aimed at strengthening industry preparedness and response strategies:

Identifying water quality risks from extreme events (Project 1063)
This research analysed 10 major Australian weather events to identify key lessons for managing water quality risks during floods and bushfires. It developed practical guidance for utilities, including Exposure Trigger Values for hazardous compounds and scenario-based risk management approaches.

Developing a Bayesian risk assessment tool (Project 1071)
With climate change increasing the likelihood of extreme events, new tools are needed to assess and mitigate water quality risks. This project created a risk assessment framework using real-world data on turbidity, colour, and blue-green algae. By incorporating Bayesian networks and System Dynamics modelling, it provides a flexible approach to predicting and managing emerging hazards.

As Australia continues to experience extreme weather, WaterRA remains committed to supporting the water sector with research, knowledge-sharing, and tools to enhance resilience.
