Impacts of combination hazards on estuarine infrastructure
Combination hazards occur when extreme events coincide (e.g. high tides and storm surges) and they present a clear and significant risk to the infrastructure in estuaries (e.g. flood defences, railways, roads, water treatment works, nuclear power stations). The NERC-funded Combination Hazard of Extreme rainfall, storm Surge & high Tide on estuarine infrastructure (CHEST) project has brought together researchers at the University of Hull and Bangor University, along with the Environment Agency and numerous project partners, to improve understanding and forecasting of these events.
The goals of CHEST are to understand the risk posed from combination hazards under present conditions and to improve our ability to forecast future risks under climate change with greater accuracy. It is will develop a novel application of a full integrated 2D hydrological-hydraulic model of combination flood hazard, incorporating all feedbacks between estuarine and fluvial systems, at much finer spatial and temporal resolutions than previous approaches. Sensitivity analyses will reveal the role hazard timing and magnitudes play under different contexts.
This presentation will provide an overview of the CHEST project, highlight the progress that has been made to date, and disseminate the initial results.
