While previous editions of ARR have served the engineering profession well, a number of issues have necessitated the production of a new edition. These issues include the many recent developments in knowledge regarding rainfall-runoff processes, the increased computational capacity available to engineering hydrologists, and the rapidly expanding body of information about climate change. As part of the development of the new edition, it has been necessary to review methods used and the implications of assumptions necessary for implementation of these methods. Arising from this review, a way forward for design flood estimation in Australia has been proposed that addresses many of the simplifying assumptions inherent in past methods and enables the inclusion of the hydrological impacts of changing climates which include changing rainfall characteristics, changing catchment vegetation, and changing catchment geomorphology. This new vision for design flood estimation will be incorporated in the new edition of ARR.
