iCOASST: using morphological modelling to guide decision-making at the coast

This presentation will summarise the outcomes of the most recent work undertaken as part of the dissemination phase of the iCOASST project (REF) including: (1) An evaluation (using pilot site modelling work developed for the Suffolk coastline)of whether, by using outputs from the iCOASST reduced complexity models of coastal morphology as inputs to the State of the Nation flood risk models, an improved assessment of future flood risk (taking account of long-term coastal morphological change, including change resulting from sea level rise and management interventions) could be achieved; and (2) the guidance document developed for coastal managers to help them better understand the value and use of morphological modelling in supporting decision making at the coast. The pilot site modelling work delivers important knowledge for future coastal FRA and model sensitivity testing; the guidance provides a unique, one-stop shop for coastal managers in explaining key coastal processes, their drivers, and the basic principles underpinning morphological modelling. It also provides a simple decision support tool that facilitates an evaluation of model applicability for a range of site characteristics
