Dive into Australian Rainfall and Runoff

Registrations are now open for Australian Rainfall and Runoff (ARR) training workshops being held around the country by Engineers Australia (EA).

Now in its fourth edition, ARR is a national guideline document, data and software suite that can be used for the estimation of design flood characteristics in Australia. The latest update to ARR was made in November 2016.

Over the course of a two-day workshop, expert facilitators will provide an introduction to ARR and its latest update, as well as deliver an advanced practical application workshop.

Workshop participants will learn how consistent use of ARR can reduce flood risk and contribute to the development of safe and sustainable infrastructure.

Participants have the option to attend either day one or day two, or the full workshop.

Suitable for all professionals working within the water industry, day one will deliver an overview of ARR guidelines and tools, and the updates to best practice outlined in the fourth edition.

Day two is designed for  practitioners involved in managing flood impact and modelling, including hydrologists and engineers. This workshop will detail how to practically apply the tools, techniques and software of ARR. Participants attending day two must be actively working within hydrology or water-related fields with some knowledge of ARR.

Workshops have been confirmed for the following cities and dates, and will run from 9:00am to 5:00pm on each day.

ARR Update December 2017

FORMATION OF THE NATIONAL COMMITTEE ON WATER ENGINEERING (NCWE) ARR MANAGEMENT SUBCOMMITTEE

On behalf of the Australian Government, Geoscience Australia (GA) has asked the NCWE (a specialist committee of Engineers Australia) to continue overseeing the technical direction of ARR. ARR's success comes from practitioners and researchers driving its development; and the NCWE is the appropriate organisation to  oversee this work. The NCWE has formed a sub-committee to lead the ongoing management and development of ARR for the benefit of the Australian community  and the profession. Current membership of the sub-committee includes Mark Babister, Robin Connolly, Rory Nathan and Bill Weeks.

ADDRESSING FEEDBACK

The ARR team  have been working hard on finalising ARR since it was released in 2016. The team has received a lot of feedback from industry and practitioners, ranging  from substantial feedback to minor typographical errors. Much of this feedback has now been addressed. Where a decision has been made not to address the  feedback, advice has been provided as to why this was the case. A new version of ARR will be released in the first quarter of 2018 with the identified errors  corrected.

FURTHER FEEDBACK SOUGHT

A draft of Book 9 Chapter 6 has recently been completed and invitations are being sought  for those interested in being part of the initial review by industry before a broader release. Please email hazards@ga.gov.au by the 8 January 2018 if you are interested in being involved. It is envisaged that the updated guidelines will be released in their entirety in the first quarter of 2018 for any final comment. Industry will be notified of these dates via the ARR subscriber list.

HOW IS ARR 2016 DIFFERENT?

ARR 2016 is deliberately different to ARR1987, which it replaces. The technical editors and  authors made a decision early in the revision to make ARR 2016 a guideline for modern best practice hydrology analysis. Australian data has been used as well as the latest techniques. It has less focus on providing detailed 'recipes' than was the case in ARR1987, but has been developed to allow application of modern methods supported by accepted engineering research. While this may mean  that there is some additional effort needed to apply these new techniques, this  effort is justified by the improvement in the design flood estimate. Other key  changes in ARR 2016 are summarised at http://arr.ga.gov.au/about.

DELIVERY OF ARR 2016

Following feedback, ARR 2016 will be delivered in a number of formats including PDF. A PDF of the whole document will be produced as well as of individual books. Improvements are also being made to the website referencing. An ePub version of ARR 2016 will continue to also be produced for those who prefer this format.

ARR DATA HUB MAINTENANCE

The ARR Data  Hub will be offline for maintenance on Thursday 21 December. While every effort will be made to minimise outages, it is possible that access may be interrupted  for several days.

TRAINING

Dates and venues for training are currently being finalised and will be announced as soon  as possible via the ARR subscriber list. The training program will feature the editors and key authors of ARR chapters.

DESIGN RAINFALLS UPDATE

In response to numerous requests for the grids of the design rainfalls, the Bureau of Meteorology is providing a service whereby the gridded  data for a specific catchment area will be provided upon request. Requests should be sent to ifdrevision@bom.gov.au.

KEEPING INFORMED OF ARR UPDATES

The digital delivery of ARR 2016 allows minor updates to be made immediately without a complete edition update being required. When major  updates occur, the year will change in the title. Users will be notified of changes by the ARR subscriber list.
