PROJECT SUMMARY

The Environment Agency has produced new practical guidance for asset managers on ways of assessing deterioration of typical flood and coastal defence assets and their residual life.

 The new guidance will help support asset managers in all Flood and Coastal Risk Management operating authorities in assessing the residual risk of assets under different conditions and maintenance regimes. It will also help them to determine the timing of required interventions and eventual replacement of assets.

 The guidance is based on a wide range of evidence ranging from historic data, targeted monitoring and expert input from practitioners to capture how asset deterioration varies under a range of different maintenance regimes, environmental conditions and loading.

 This new evidence and guidance is a valuable resource for asset managers in all operating authorities for

•             Assessing the residual risk of assets under different conditions and maintenance regimes

•             Determining the timing of required interventions and eventual replacement of assets

It has also benefits for other applications, such as assessing changes to a wider stock of assets as part of strategic assessments of future investment and funding needs.

 As deterioration can vary from asset to asset, it is essential to use engineering judgement and practical experience alongside this guidance to apply and adapt the deterioration curves appropriately.

 The guidance is supported by a technical report that describes the methods, tools and data used during the development of this guidance.
