This project has explored ways to assess the performance and reliability of flood and coastal defences in order to make better assessments of risk. It directly supports Defra and Environment Agency policies, strategies and new decision-making tools for flood and coastal erosion risk management. In particular: • it provides information to assess the effectiveness of flood defences in reducing risk • it provides information to support decision-making on how to manage the performance of flood defences • it provides methods to help to assess flood and erosion risk including performance of defences under extreme loads. The reports describe the scientific and practical basis for fragility curves, and their role in the risk and performance based management framework. They are intended to inform and assist those involved with managing flood and coastal defences, and assessing risk associated with flood defence structures and systems.


To identify methods and provide guidance on best practice approaches for assessing the reliability of defence linear structures, supporting the overall joint R&D programme objective of developing improved risk-based managing. KEY


FD2318 will provide a significant step towards delivering better risk based management decisions through the promotion and development of key underlying concepts concerned with the characterisation of defence performance as a function of its fragility.
