Dam Spillways (May 2015) – MODULES 1 TO 4
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:
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.
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.
Technical Seminar: Safety Evaluation of Existing Dams Day 3 – MODULE 1- 4
This seminar emphasises the importance of periodic evaluation of the safety of existing dams, and provides specific information and guidance on the visual and instrumented monitoring of the various types of dams and their appurtenant structures. Failure modes analysis is stressed as the basis for an effective and efficient monitoring program. At the conclusion of the course, attendees will have a thorough understanding of the procedures and techniques essential to carrying out meaningful dam safety evaluations and monitoring, and should be able to apply these principles to improve their own effectiveness and the effectiveness of their dam safety programs.
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.
