SOLVING A 40-YEAR OLD COASTAL SEDIMENT TRANSPORT PROBLEM USING INTEGRATED FIELD AND MODELLING APPROACH

Case studies provide valuable lessons for successfully solving coastal engineering and management challenges. This paper gives an overview of a typical man-made coastal sediment trap case and presents a multi-method research carried out at different time scales into solving the problem. In the context of previous geological, oceano- graphic and historic research in the eastern Baltic Sea, the paper presents new results based on discreet water flow measurements, beach profiling as well as analysis of orthophotos and bathymetric data. These data were coupled with SWAN modelled waves and currents with resulting sediment transport in Delft3D. With relatively small budget we were able to get novel results which are used in the future management of the study area in the changing climate.
