As Australia's climate landscape changes, the updated Australian Rainfall and Runoff (ARR) Guidelines enables practitioners, designers and decision makers to appropriately consider the impacts of climate change in their flood estimation and management.

Join our expert panel discussion where we discuss the implications of these updates offering insights from leading professionals. This session will provide participants with a more robust understanding of future flood risks, incorporating projections of rainfall intensity and the latest research on extreme rainfall events and its implications for the water sector.

The new ARR climate change guidelines, based on the IPCC’s Fifth Assessment Report, has significant implications for water planning and management.

The guidelines recognise that the impacts of climate change are not uniform across Australia and as such we need a better way at considering climate change impacts on flood estimation. The key changes demonstrates actions taken to support effective climate risk management, raising awareness on how to adjust design flood estimation methods to account for the effects of rising global temperatures on rainfall.

This paradigm shift necessitates re-evaluating existing water management strategies to ensure they are robust and adaptive to these heightened and more complex climate risks, empowering you to take proactive measures.


Webinar Outline

This 90 minute webinar will include:

  • Dr. Conrad Wasko, lead of the Technical Working Group Update to the Climate Change Considerations chapter of ARR, presenting on the climate change science.
  • Monique Retallick presenting on possible changes to design flood recurrence.
  • Prof. Rory Nathan will chair a panel discussion on the considerations and implications of the climate change update.

This webinar event is designed to capture the interests of a broad audience including:

  • Practitioners who use the guidelines to produce flood information for decision makers.
  • Decision and policy makers who use the flood information for designing effective policies for the future.
  • Government regulators.
  • Floodplain managers.
  • Asset owners.
