ARR 1987 acknowledged the emerging issue of climate change. ARR 2019 provided National guidance on climate change related rainfall increases based on advice from an expert group including CSIRO, BOM and various academic experts.
The major areas where climate change will impact flooding are:
• Design rainfall intensity-frequency-duration.
• Storm type, frequency and depth.
• Rainfall spatial and temporal patterns.
• Antecedent conditions.
• Changes in sea level.
• The joint probability of storm surge and flood producing rainfall.
This seminar will cover what is the current advice on climate change relating to flooding and how to implement it in practice. It will also cover how the current interim advice may be superseded. The seminar will discuss how climate change will affect urban catchments versus rural catchments.
