Australian Rainfall and Runoff (ARR) is a national guideline for flood risk estimation. AR&R provides guidance and datasets to produce accurate and consistent flood studies and mapping to ensure communities, infrastructure and the environment can withstand the impact of extreme rainfall, flooding and storm surge.

In 2016 the first major update to the guidelines in nearly 30 years was published. The modernisation of the guidelines and the accompanying data and software takes into account the significant technological advances in rainfall and runoff assessment since the previous edition.

The 2017 Stormwater WA Awards for Excellence was held at the 2018 Hydropolis and WSUD conference dinner, on 14th February 2018 at Crown Towers, Perth.  With the State Minister for Water; Fisheries; Forestry; Innovation and ICT; Science, the HON Dave Kelly BA MLA in attendance, and Water Corporation CEO Sue Murphy as MC, awards dinner attendees were treated to a Valentine’s Day evening with delicious food, good music and a room full of (mostly) engineers to celebrate with. And none were happier more than the awards winners themselves:
