ARR testing

12 Aug 2015

Australian Rainfall and Runoff (ARR) is a national guideline document, data and software suite that can be used for the estimation of design flood characteristics in Australia.

The document Australian Rainfall and Runoff was first published by Engineers Australia in 1958. It  has since become an essential guidance document for the practice of hydrology in Australia. The last major upgrade was in 1987.

The National Committee on Water Engineering, Engineers Australia, in conjunction with Geoscience Australia updated the document in 2016. The update included revision of the document, update of design information with new data and methods and development of new tools. The new guidelines, tools and data are available on the ARR project website.

The ARR revision project occurred over a number of years. The project contracted a number of industry practitioners to develop and test the tools and techniques.
