摘要: While previous editions of ARR have served the engineering profession well, a number issues necessitated production new edition. These include many recent developments in knowledge about rainfall-runoff processes, increased computational capacity available to hydrologists, and rapidly expanding body information climate change. As part development edition, it has been necessary look at history methods used implications assumptions for implementation these methods. Arising from this review, way forward design flood estimation Australia is proposed that addresses simplifying inherent past but also recognises differing levels complexity required estimation. This vision will be incorporated edition ARR.
