Australian Rainfall and Runoff (ARR) is a national guideline document for the estimation of design flood characteristics in Australia. It is published by Engineers Australia. The current 1987/1999 Edition has served the industry well but is now being revised. The revision process includes 21 research projects, which have been designed to fill knowledge gaps that have arisen since the 1987 edition.
Keeping ARR up-to-date is an important component in the provision of reliable (robust) estimates of flood risk. This ensures that development does not occur in high risk areas and that infrastructure is appropriately designed. The ARR Research Projects shortly will be finishing Stage 2. Stage 1 and 2 were funded by the Federal Department of Climate Change and Energy Efficiency. BoM has been funding Stage 2 and 3 of the IFD revision. Geoscience Australia will fund Engineers Australia $5.15 million over three years to complete the vital third and final stage. This was made possible through funding provided by the Australian Government through the National Flood Risk Information Project.
Parallel to the research projects is the updating of the document. The research projects will allow industry to comment on the technical direction before the new edition of ARR is released.
