Australian Rainfall and Runoff (ARR) is the national flood estimation guideline. The last edition was published in 1987.

Technology and methods have evolved since that time and the 2016 edition incorporates 30
years of extra rainfall data, updated techniques and methodologies. This seminar provides an introduction to what has changed in the new ARR, focusing on the more general structural, civil and hydraulic engineering uses.

The seminar will include a demonstration of the new user friendly software suitable for use by non-
specialist hydrologists including the regional flood frequency software.

Mark Babister, the presenter, is the Managing Director of WMAwater Pty Ltd with over 25 years of experience in water engineering studies. He is the chair of the Technical Committee that is overseeing the ARR update and the editor of Australian Rainfall and Runoff Project 15 – Two Dimensional modelling of Urban and Rural floodplains.
