Interim Guide To Quantitative Risk Assessment for UK Reservoirs

In particular the guide provides for:
* estimating the annual probability of failure of a dam
* assessing the consequences if the dam failed, both in terms of the likely loss of life and direct third party damage
* evaluating the risk posed by the dam, in terms of both £/annum and the risk of loss
* Determining whether the risk posed by the dam is tolerable, in that the cost of reducing the risk would be disproportionate to the reduction in risk achieved.

It also provides an opportunity for the user to decide whether there are any other threats that may constitute a significant probability of failure and should therefore be quantified. Later sections provide for the estimation of the consequences of failure.

The guide also come with a CD-Rom containing Microsoft Excel workbooks with proforma calculations, and accompanying text. This forms part of either a periodic safety review or a portfolio risk assessment. Where application of this guide identifies potential concerns a more detailed assessment is likely to be appropriate
