Paul Sayers provides evidence to Infrastructure Review

Paul Sayers provided a summary of the climate impacts on the performance of flood defence infrastructure to the LWEC / Environment Agency sponsored investigation. The analysis provided was published in 2015 by the Institution of Civil Engineers.

His review highlighted that climate change can affect the performance of flood and coastal erosion risk management infrastructure (FCERMi) through a number of mechanisms. This review highlights that whilst it is well known that climate change can influence the performance of FCERMi in a number of ways, there is extremely poor quantitative understanding of the physical processes of time-dependent deterioration and the impact of changing loads (and the interactions between these) on the reliability of FCERMi. If FCERMi is to be more robust to future climate uncertainties, there is an urgent need for research to better understand these interactions in the long-term. This must be coupled with an updated approach to design and management that considers changes in extreme values, storm sequencing, spatial coherence, or more subtle impacts from changes in temperature, solar radiation and combinatorial affects.
