Dam Types, Foundation & Construction (November 2014) – MODULES 1 to 5 (Full Seminar)
COURSE OBJECTIVES AND OUTLINE
This short course is designed to provide sound basic understanding into dam types, foundations and construction, their key issues and considerations including investigations and design and addressing new and existing dams and associated upgrades.
It will begin with looking at all the various types of embankment and concrete dams, their issues and considerations as a lead into choosing or reviewing dam type and associated upgrade including risk assessment, historical performance and basic monitoring for dam safety.
Next foundations types and associated investigations, design and construction key aspects will be covered in view of the importance of this component for both new and existing dams.
To round off basic dam understanding the final sessions will concentrate on preliminary and common construction considerations and in particular construction of embankment and concrete dam walls.
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.
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 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.
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.
Dam Spillways (May 2015) – MODULES 1 TO 4
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.
