Current practice dictates that a dams should have spillway capacities so as not to expose the downstream population and environment to an intolerable risk of dam failure.

These dam safety guidelines are intended to apply to what might be termed conventional dams eg. ANCOLD has prepared these important Guidelines to provide a consistent method of categorising the consequences of dam failure so that resources can be allocated according to the potential effects of failure on the general community.

There are purpose built flood retention basins typically situated within urban environments to reduce the effects of flash flooding. These guidelines are not a design, construction or operation code, and dams personnel must continue to apply their own considerations, judgements and professional skills when designing and managing tailings dams.

In the ten years since the release these Guidelines there has been considerable increase in the recognition of environmental responsibilities by the mining industry and its regulators, particularly in addressing the concept of sustainable mining.

The community will decide the future of water resources and dams in the 21 st century. In applying them, it must be remembered that they are guidelines only to what is considered current acceptable practice and allow owners and practitioners flexibility to exercise professional judgment in all aspects.

It also gives us the tools to estimate what these will be after any improvement.

This companion volume focuses on:. There are periods of high rainfall followed by long droughts. Indeed, without the application of such judgment, the procedures themselves could lead to results that have serious shortcomings. The objective of this companion volume to the Environmental Guideline is to increase environmental awareness by encouraging more sustainable planning, design, construction and operation inputs to large dams. River navigation, particularly along the River Murray, provided a major role in developing the agricultural potential of northern Victoria and southern NSW.


This has allowed many marginal arid areas to be developed into high yielding food bowls. The Watching Brief Guidelines for Dam Instrumentation and Monitoring Systemsestablished following the Dam Instrumentation Workshop in Sydney, continues to scan for information and topical developments related to the monitoring of dams using a range of instrumentation techniques. Mining tailings can have concentrations of heavy metals, highly acidic waters, and other environmentally damaging substances.

Whilst specific to the Australian considerations the majority of this guideline could be applied to dam structures throughout the world. It is required for domestic use, sanitation, industry and agriculture as well as recreation boating, swimming, fishing and visual amenity. In the ten years since the release these Guidelines there has been considerable increase in the recognition of environmental responsibilities by the mining industry and its regulators, particularly in addressing the concept of sustainable mining.

Background on ANCOLD |

ANCOLD is guidelinse of the diversity of dams and the circumstance associated with them and offers this document merely guidellines an indicator of the approach that may be taken. For these reasons, ANCOLD puts this guideline forward as an advisory document that must be interpreted by appropriately qualified and experienced professionals in each case.

The new guidelines include much of the original guidelines but with appropriate updating. As such this companion volume complements rather than replaces the existing guideline. There is much focus on guidelinew dams and water management schemes, however, the role and value of small and medium dams should not be understated. As time goes on there will be improvement in contemporary dam practice and it is intended that ANCOLD guidelines will be updated as circumstances dictate.

With this in mind, comment from users and others is welcomed.

Guidelines on Dam Safety Management () |

There are several ways this can be achieved, including: ANCOLD has prepared these new guidelines to provide a single base document that supports the DITR publication and others like it, with engineering detail that can be accepted by all relevant government authorities, and national and international companies involved in tailings dam development, allowing them to undertake design and anxold consistent with leading industry practice.


In keeping with this principle, this revision of the guidelines has the section on foundations at the front of the document. Describing the complex Commonwealth and individual State regulatory environments guidleines must be dealt with in all dam projects.

A position paper outlining the current status for the Executive is planned guideliines and will provide a mechanism to move forward on the need for an updated guideline.


The application of risk assessment involves a major philosophical addition to, and enhancement of the deterministic standards developed over many years for appropriate safety of dams. The protection of the population from the more frequent small to medium floods gives an expectation that they are also protected from the more infrequent large floods. Australian large dams are generally designed and assessed for their capacity to withstand the types of earthquakes that could credibly occur in our area.

Meteorological models indicate that intense rainfall is more likely in the future due to climate change. As a non-government, non-profit and voluntary association of organisations and individual professionals with a common technical interest in dams ANCOLD currently has 53 member organisations and individual associate members covering all aspects of the dams industry.

Rainfall patterns and locations can be patchy and inconsistent and rain does not always fall when and where we wish it. The two guidelines should be regarded as companion volumes for reference, with the Guidelines providing a targeted and practical environmental perspective. The understanding of the effect of earthquake on dams has developed over the past two decades. The dam, which forms […]. The Guidelines are intended to be regularly updated to reflect the changing regulatory environment as well as increasing technical knowledge about environmental management.
