Dam Spillways (May 2015) – MODULE 1
Seminar Welcome & Closure
COURSE OBJECTIVES AND OUTLINE
This short course is designed so that engineers and other dam professionals both young and more experienced will better understand the essential ingredients of investigation, design, operation, maintenance and safety for spillways and outlets for new and existing dams and associated upgrades.
While ensuring the basics are properly understood, there will be a strong focus on what is the approaches, issues and risks associated modern dam spillways & outlets requirements – what you need to know, whether a dam owner/manager/operator, consultant, regulator or a professional with a strong interest in dams.
Dam Spillways will look at spillways which are being called upon to handle larger and larger discharges due to revisions to hydrology data, trends in risk evaluation and other issues. It covers both broad criteria for sound spillways (including ungated, gated & fused spillways) and the specific criteria to enable a proper understanding of how and why spillways work or don’t work or what needs to be improved, how to be confident in their operation, how to maintain them and overall make them safe. It will include descriptions of a range of cases – particularly those which have shown a new understanding and respect for large discharges, risks and overall safety and best practice management of spillways.
Includes access to the following videos:
Dam Safety Emergency Planning (June 2014) – MODULES 1 TO 5 (FULL COURSE)
COURSE OBJECTIVES AND OUTLINE
This short course is designed to provide a comprehensive understanding of all aspects of dam safety emergency planning including developing, using, exercising and reviewing dam safety emergency plans.
It will begin by briefly reaffirming why dam safety emergency plans are needed and then provide a high level overview of legislative requirements for each State.
Critical elements of dam safety emergency planning and plans will be presented in detail. This will be followed by guidance on how to develop and document dam safety emergency plans.
The seminar also includes modules on training operators and emergency responders in the use of dam safety emergency plans and exercising them so that everyone is confident that the plan will work in a genuine emergency.
The presenters will use examples from their experience to illustrate all aspects of dam safety emergency planning and there will be opportunities for delegates to ask questions and share their experiences throughout the day.
Retarding Basin Fundamentals (April 2013) – MODULE 1 TO 4
Retarding basins are becoming increasingly important elements in urban flood planning throughout Australia but it is evident that many basins have not been implemented in line with modern day “risk management” approaches. Accordingly, as part of its Professional Development program, and in advance of its proposed Guideline on Retarding Basins due out in 2014, the Australian National Committee on Large Dams (ANCOLD) is planning a series of seminars across Australia on Retarding Basin Fundamentals. The seminars are being provided to assist basin owners, and their professional staff and advisors, to plan, implement and operate their basins in a safe and effective manner consistent with various Government and “duty of care” obligations.
The one day seminars are being presented by leading dam safety and risk management professionals including:
Richard Rodd- dams consultant with over 40 years experience in dam and basin design, construction, operation and maintenance.
Kelly Maslin – dams consultant with over 15 years experience in dams and risk management.
Norm Himsley – dams consultant and member of NSW Dam Safety Committee with over 40 years experience in dam and basin design, construction, operation and maintenance.
Dam Outlets will look at the other key passage of water passed a dam – outlets. Like spillways it will cover both broad criteria for sound outlets (including intakes) and the specific criteria on the various purposes and types of outlets and in some cases combined with spillways or power generation. Experience of the presenters and case studies will provide a key input into the issues, risks, environmental aspects (such as thermal and fish passage) and overall safety and best practice design and management of outlets. Importantly the presentation will provide an essential insight into the new ANCOLD guideline on outlets currently being prepared.
Hydrometeorology and Hydrology (September 2013) – MODULES 1 TO 5
Guidance for design flood estimation is provided in Australian Rainfall and Runoff. Since the last edition in 1987 there has been development and increasing application of stochastic simulation approaches for design flood estimation. There has been associated improved information and more sophisticated treatment of inputs such as design rainfalls, areal reduction factors, losses, baseflow and initial contents of reservoirs. A significant development has been the recent release of the new IFD estimates from the Bureau of Meteorology. The session will cover improved approaches to design flood estimation such as Mont-Carlo analysis and the characterisation of inputs.
Dambreak & Consequences (September 2013) – MODULES 1 to 5
An understanding of the consequences of dam failure is essential in dam safety emergency planning and as an input to risk assessment. In recent years there has been significant advances in hydraulic modelling and access to high quality elevation data which has revolutionised dambreak modelling. The advent of risk based approaches has increased the focus on estimating the consequence of dam failure and particularly the potential loss of life. The method developed by the USBR in 1999 has had widespread application in Australia and in recent years a number of more sophisticated simulation approaches have been developed. This session will cover the latest developments in dambreak modelling and the estimation of potential loss of life from dam failure.
This course is designed to present the state of practice on these matters for dam safety risk management. The 2 days are designed for both experienced and less experienced dam owners, regulators and consultants.
