The 3rd edition, published in 1987, retained the same level of national and international acclaim as its predecessors.  \nWith nationwide applicability, balancing the varied climates of Australia, the information and the approaches presented in Australian Rainfall and Runoff are essential for policy decisions and projects involving:  \n• infrastructure such as roads, rail, airports, bridges, dams, stormwater and sewer systems;  \n• town planning;  \n• mining;  \n• developing flood management plans for urban and rural communities;  \n• flood warnings and flood emergency management;  \n• operation of regulated river systems; and  \n• prediction of extreme flood levels.  \nHowever, many of the practices recommended in the 1987 edition ofARR have become outdated, and no longer represent industry best practice. This fact, coupled with the greater understanding of climate and flood hydrology derived from the larger data sets now available to us, has provided the primary impetus for revising these guidelines. It is hoped that this revision will lead to improved design practice, which will allow better management, policy and planning decisions to be made.  \nOne of the major responsibilities of the National Committee on Water Engineering of Engineers Australia is the periodic revision ofARR. While the NCWE had long identified the need to update ARR it had become apparent by 2002 that even with a piecemeal approach the task could not be carried out without significant financial support. In 2008 the revision of ARR was identified as a priority in the National Adaptation Framework for Climate Change which was endorsed by the Council of Australian Governments.  \nIn addition to the update, 21 projects were identified with the aim of filling knowledge gaps. Funding for Stages 1 and 2 ofthe ARR revision projects were provided by the now Department of the Environment. Stage 3 was funded by Geoscience Australia. Funding for Stages 2 and 3 of Project 1 (Development of Intensity-Frequency-Duration information across Australia) has been provided by the Bureau of Meteorology. The outcomes ofthe projects assisted the ARR Editorial Team with the compiling and writing of chapters in the revi","cbCairRKLENjwgyu","https://ap.wps.com/l/cbCairRKLENjwgyu","pdf",25716605,235,"English","# Preface\n## Purpose and application of ARR\n## Rationale for revising the 1987 edition\n## Projects and funding supporting the revision\n## Editorial team and roles\n## Status of the document","[{\"question\":\"What is Australian Rainfall and Runoff (ARR), and what is its overall purpose?\",\"answer\":\"ARR is a set of flood estimation guidelines intended to support policy decisions and engineering projects.
