A New Chapter for Australian Rainfall and Runoff

COMPLETION OF THE ARR PROJECT

The 2016 ARR is a major achievement as it is the first major update of the guidelines in nearly 30 years.

The modernisation of the ARR Guidelines, including updates to the guidelines, software and data, has largely been completed. Finalisation of the Intensity Frequency Duration (IFD) data is currently being undertaken by the Bureau of Meteorology, and we will inform you when this is complete.

The modernised guidelines provide local government engineers and consultants with the guidance and datasets necessary to produce more accurate and consistent flood studies and mapping now and into the future.

A NEW CHAPTER FOR ARR

Now that the project is nearly complete, ownership of ARR has been transferred from Engineers Australia to Geoscience Australia on behalf of the Australian Government. This arrangement means the Guidelines will be publically accessible free of charge.

The transfer will include transitioning the ARR website to a new website domain - http://arr.ga.gov.au/. The website will be regularly updated to ensure the ARR Guidelines remain current.

KEEPING INFORMED OF ARR UPDATES

Keeping the ARR up-to-date is an important component for providing reliable and robust estimates of flood risk. It also provides necessary information for locating new developments in safer areas, and appropriately designing new infrastructure.

The digital delivery of ARR 2016 allows minor updates to be made immediately without the edition being updated. When major updates occur, the year will change in the title.

We will keep you informed of any updates to ARR through this subscriber newsletter, or alternatively you can follow Geoscience Australia on Twitter.
