Consequence Assessment and Risk Management of Water Dams

If you happen to be in Brisbane on the 2nd June then, on behalf of the Queensland Panel:

Consequence Assessment and Risk Management of Water Dams

Large water dams can pose a significant flood risk to downstream communities. Recent flood events across Queensland have placed the spotlight upon the management of these dams and the way in which the impact on at-risk communities is managed.

In this technical session, Peter Allen (Department of Energy and Water Supply) will present on the latest developments in Emergency Action Plans (EAPs) including their need, statutory and practical requirements and future directions. James Stuart (SunWater) will present on operational aspects of dam risk management and lessons learnt from recent flood events. Michel Raymond (Seqwater) will discuss the concept of consequence creep and resulting higher standard of upgrades and costs to dam operators and the community.

Date: Thursday 2 Jun 2016 – 5:30 pm to 7:00 pm
Venue: Hawken Auditorium, Engineering House, Level 1, 447 Upper Edward Street, Spring Hill 4004
Cost: EA Members & Students $10.00, Non-members $40.00

Registration is available online.

EEA 2-Day Stormwater Managment Workshop: June 2016

A 2-day Workshop entitled “Stormwater Management (source control)” has been organised by EEA (Engineering Education, Australia) for Thursday/Friday 2/3 June 2016 in Sydney. The Notes provided in the course are based on the content of the award-winning manual “WSUD: basic procedures for ‘source control’ of stormwater – a Handbook for Australian practice” edited by Professor John Argue AO (University of South Australia). This document is endorsed by Stormwater Industry Association (SIA), Australian Water Association (AWA) and by Dept of Water, Western Australia; it is included as a major reference in Book 9, Chapter 5 of the 2015 Australian Rainfall Runoff Revision (AR&R).

The content features a balance between the three domains of WSUD (stormwater) practice – quantity control, pollution control and stormwater harvesting. Serious issues of stormwater management in Australia are posed by the prospect of 35 million population of Australia by 2050.

How will Sydney’s existing stormwater infrastructure and that of other major population centres in NSW cope with change under the ‘high density’ option presently being implemented across the State ?
What strategies can be adopted to enable existing (competently-performing) infrastructure to manage these changes without expensive (conventional) upgrade?
How can re-development in catchments with existing under-performing stormwater infrastructure be managed to enable the existing in-ground works to progressively meet greater demand without expensive (conventional) upgrade?
Must the creeks and natural waterways falling within the jurisdictions of metropolitan and regional municipal agencies within and outside Sydney be sacrificed to hard-lining in the wake of the proposed expansion?

Positive answers to these and many other questions based on WSUD ‘source control’ practice will be provided in the Workshop as well as a 30-minute presentation by Dr Markus Botte on how the City of Gosnells has incorporated this practice into its cost-effective urban re-growth strategy.

The Workshop will also include results of continuous simulation modelling of high-performing filter-bioretention systems enhanced by treatment taking place in parent soil masses; the fate of dissolved pollutants is singled out for particular attention.

The short course includes: design procedures based on state-of-the-art analyses and best overseas practices adapted to Australia-wide conditions; case study illustrations drawn from field installations with between 10 and 18 years of Australian operational history; design ‘worked examples’; introduction and access to rainwater tank sizing software applicable across Australia. The Workshop will be led by Professor John Argue AO.

Why you should attend the Workshop:

It is presented only once per year in Sydney;
It covers the three main domains of WSUD practice – quantity (urban flooding), quality (pollution treatment/control) and stormwater harvesting – in a comprehensive, integrated manner;
The (stormwater) retention practices covered in the Workshop are offered in the 2015 AR&R Revision alongside those of detention practice (Book 9, Chapter 5);
It earns participants 32 hours of CPD credit with Engineers Australia.

ARR/WSUD Workshop

Overview (Updated 2015-08-11)

The ARR team, in conjunction with the 9th International WSUD Conference, are running an workshop to discuss the latest developments in the ARR revision, specifically in the WSUD and urban drainage space. Topics covered will include an overview of the new short duration IFDs and synthetic rainfall for continuous simulation as well as the design of retarding basins. Dr Peter Coombes will also be presenting on current directions in urban drainage.

When ARR is released there will be significant changes to the recommendations and guidelines across the hydrologic sector, with major flow on consequences to engineering and ecologic practice. This workshop is intended to introduce these changes to practitioners working in the fields of WSUD, short duration design and analysis as well as continuous simulation for process modelling. It is also a significant opportunity for industry practitioners to provide feedback to ARR authors and the editorial team into the direction and final outputs of ARR, which is scheduled for launch later this year.

Book 3 – Peak Flow Estimation released for industry comment

The ARR team is pleased to announce the first complete draft book of the 4th edition of Australian Rainfall and Runoff is released for industry comment. Book 3 covers both regional and at site flood frequency estimation techniques. The at site flood frequency chapter is a significant change from the version previously available (Kuczera and Franks, 2006) and supersedes this version. Please note that this is a draft and as such some of the figures, examples and formatting have not been finalised. The report will be available for industry comment until the end of April. Software for the regional flood frequency estimation method is in the final stages of testing and will be released soon. FLIKE will be also be commercially available for a small price from TUFLOW in the near future.

Project 5- regional flood methods – stage 3 report release

In conjunction with the release of Book 3 Chapter 3 Regional Flood Frequency Estimation the Project 5 regional flood methods stage 3 report and data report by the University of Western Sydney team (lead by Dr Ataur Rahman) are being released. This report provides more detail on the method and supplements the chapter. Stage 3 is the final stage of the project which began in 2008. Thank you to all the project team, state teams and government organisations that provided data for this nationally significant project. This project is a significant advance on the techniques in ARR 1987.

Best Practices for Use of Pre-Releasing for Flood Management

The Panel’s first presentation for 2015 is titled “Use of Pre-Releasing for Flood Management: Best Practices at Leading Dam Owners around the World” and will be given by Dr Amit Chanan.

30th April 2015
5.30 for 6pm Start

Engineers Australia Auditorium
Ground Floor, 8 Thomas St,
Chatswood NSW 2067

Pre-registration is mandatory and while the event is free for Engineers Australia members, non-members entry is $30.

Abstract

Pre-releasing is a dam operating methodology that involves releasing water prior to an expected flood event to create airspace within the dam. The airspace is created with the aim to capture the first of the floodwaters. The presentation compares flood operating procedures for major gated dams at leading dam owners in the USA, Canada, and UK, particularly focusing the role of ‘pre-releasing’ during floods.

The millennium drought was broken in the South-Eastern Australia by major floods in December 2010, followed by another significant wet season in March 2012. This period saw major flooding in the cities of Brisbane, Wagga Wagga and parts of Victoria.

Operation of dams during these floods came under heavy media scrutiny. In case of Brisbane a Commission of Inquiry investigated the operations of Wivenhoe Dam. Similarly, a Ministerial review looked at operations of Burrinjuck and Blowering dams in relation to flooding at Wagga Wagga. Victorian Government also commissioned a review of floods in that state.

Biography

Dr Amit Chanan is a Visiting Fellow at the University of Technology Sydney. His professional career spreads over two decades within the water industry, including senior executive roles within the NSW State Government and local government. Amit is a Fellow of Engineering Australia. He is the Vice Chair of the International Water Association’s Specialist Group on Water Security and Safety Management.
