Austroads: Transport Research and Trends

In response to feedback provided by industry and stakeholders, Austroads has reviewed its Guide to Road Design Part 5: Drainage – General and Hydrology Considerations.

The improved guidance responds to the implications for road authority and consulting engineering practices arising from the 2019 update of the Australian Rainfall and Runoff document.

This is the second webinar in a two-webinar series, and it covers the improvements made to the Regional Flood Frequency Estimation (RFFE) method.

The following is discussed in the session:

• Background to the RFFE method
• Recent improvements to the RFFE method
• Worked examples
• Limitations of RFFE and how to assess the quality of the answers produced

The webinar is presented by WMAwater’s Managing Director Mark Babister and William Weeks, currently a private consultant and former Director - Hydraulics and Flooding for the Queensland Department of Transport and Main Roads.
