BoM Design Rainfalls Web Page Updated
4th March 2017
As discussed at the FMA’s NSW/ACT Chapter Meeting in Sydney on 23 February the Bureau of Meteorology has updated its design rainfalls web page to include:
- very frequent design rainfalls, for probabilities from 12 Exceedances per Year (EY) to 0.2 EY
- rare design rainfalls, for probabilities from 1?in?100 Annual Exceedance Probability (AEP) to 1?in?2000 AEP
- the ability to extract design rainfalls as either depths (in millimetres) or intensities (in millimetres per hour).
The 2016 design rainfalls and technical advice are available at: bom.gov.au/water/
They should be used in conjunction with the 2016 edition of Australian Rainfall and Runoff: A Guide to Flood Estimation (ARR2016), available from the Geoscience Australia web site: http://arr.ga.gov.au/.
