Dr Mike Barry and Dr Peter Coombes were awarded the 2018 GN Alexander Medal by the Engineers Australia National Committee on Water Engineering for their systems framework research into the Melbourne and Sydney regions, this follows a runner up for the development of the systems framework approaches in 2014. The award is discussed on line at https://lnkd.in/dzks2RV and https://bit.ly/2EaW9f7 The research demonstrated that the application of average assumptions of any kind is problematic and has the potential to heavily influence infrastructure investment, policy direction and cannot account for integrated solutions. Indeed, use of centralised average assumptions can underestimate the benefits of local solutions, such as WSUD, and can provides an illusion of no benefits.
