Working in collaboration with key authors of ARR 4th edition, the Australian Water School has created the ARR On-demand Training Series.

The On-demand Training Series allows attendees access to the video recordings of the Live Training Series sessions and be provided with the same case studies, exercises, and homework as the live training to turn ARR policy and research into practice.

All the on-demand courses are go-at-your-own-pace and you can repeat the recordings as many times as you like.

ARR On-demand Training Series

The ARR Series includes 2 free webinars ARR Essentials and What’s new with ARR, which introduce attendees to the fundamentals of ARR (including the data hub and software), its core concepts, key topics and approaches and also Book 1 of the Guideline- Scope and Philosophy.

ARR Essentials lead into the Training Series comprised of 8 individual intensive 3-hour courses. Each course in the series focuses on a key topic of the guide.

Every course is hosted by experts in their field, who delve in-depth into the key topic, explaining best practice techniques and approaches.

Attendees will be introduced to, and work on, practical examples and case-studies, allowing them to apply the knowledge from the ARR Guidelines and learn, hands-on how to use the Data Hub and software.


Australian Rainfall and Runoff (ARR) is the national guideline document, data and software suite for the estimation of design flood characteristics in Australia.

Originally published in 1958 by Engineers Australia, ARR 4th edition was released in 2019 with support of the Commonwealth Government of Australia and Geoscience Australia. With national applicability, balancing the varied climates of Australia, it is a pivotal framework to the safety and sustainability of Australian infrastructure, communities and the environment. The information and the approaches presented in Australian Rainfall and Runoff are essential for policy decisions and projects involving:

  • infrastructure such as roads, rail, airports, bridges, dams, stormwater and sewer systems;
  • town planning;
  • mining;
  • developing flood management plans for urban and rural communities;
  • flood warnings and flood emergency management;
  • operation of regulated river systems; and
  • estimation of extreme flood levels.

ARR 4th edition is a major update to guidelines, the first in 30 years and consists of The Guidelines and associated Data hub and software.

How it works

AWS designed the ARR On-demand Training to be delivered as a series with each course flowing into the next. This enables attendees to build their skills piece by piece through every course and understand all aspects of ARR.

What’s included

The ARR On-demand Training Series is designed to be taken individually. Each course is highly practical and hands-on (ie; not simply a PowerPoint of lectures), turning ARR policy and research into practice.

To provide the best-desired learning outcomes, setup in a quiet space with dual monitors (ie one screen with the session recordings and the other with the software/exercise that attendees can work on simultaneously). The courses are not designed for a board-room setup.

Dependent on the course, attendees will be interacting and developing models, learning software, working through exercises and case studies. Where relevant, attendees will also have homework between courses.

What’s included within each of the 8 On-demand courses in the series:

  • 3-hours of session recordings to view as many times as required within the allocated time;
  • Ability to ask questions to the presenters at anytime through the learning platform;
  • PDF manual of the course. The manual is recommended for ongoing use;
  • Any working models/ software’s necessary as per instructions in individual course, downloaded from the learning platform before starting the session recordings;
  • Most courses have exercises / homework to complete between courses;
  • Pre-reading and viewing materials;
  • Ability to access all the online course materials within the allocated time. The pre-readings and manual are available for ongoing learning;
  • Attendees earn CPD hours/points (ie with Engineers Australia) for at least 5 hours per-course (therefore 40+ hours for the Series).
