Abstract:

Our overall goal is to achieve a better understanding and better predictions of coastal behaviour at intermediate eventseasonyeardecade scales. We aim to bring together researchers from Europe and North America to gain the best possible benefit from developments in field observation, theory, and numerical modeling. We are following a four-pronged collaborative approach. Data on intermediate-scale behaviour from both sides of the Atlantic are being studied and ways are being sought to project these observations onto a manageable number of descriptive parameters or basic patterns. Top-down modeling uses these data products to develop black-box data extrapolation and grey-box behaviour-oriented models for the observed behaviour. Bottom-up modeling investigates the predictive potential of process-based models, making the best use of process results from U.S. and European field campaigns, combined with existing modeling expertise. There is also a vital linking activity aimed at ensuring that the data, top-down modeling, and bottom-up modeling activities interact fully to bring together the most productive aspects of each into a predictive capability for intermediate-scale coastal change. Explicit recognition of the need to consider predictive skills of coastal morphology models is driving much of our research and will have an important impact on the practical as well as research aspects of coastal science.
