Coastal Study of Three-dimensional Sand Transport Processes and Morphodynamics

The purpose of the COAST3D project is
- to improve understanding of the physics of coastal sand transport and mrophodynamics.
- to remedy the present lack of validation data of sand transport and morphology suitable for testing numerical models of coastal processes.
- to test a representative sample of numerical models for predicting coastal sand transport and morphodynamics against this data.
- to deliver validated modelling tools, and methodologies for their use, in a form suitable for coastal zone management.

This will be achieved by making field measurements purpose-designed for numerical model evaluation, with adequate boundary conditions and a dense horizontal array of measurement points, in conditions typical of the European coastline. Previous coastal experiments in Europe and elsewhere have placed their main emphasis on hydrodynamics; an innovative feature of the present project is that the emphasis throughout is on sand transport and morphodynamics.

Another distinctive feature is that the focus is on non-uniform (3D) coasts, rather than on the relitively well understood (but possibly unrealistic) uniform 2D case. Experiments will be performed at two contrasting sites: a quasi-uniform (2.5D) stretch of the Dutch coastline, in which the three-dimensionality is provided by rip-channels intersecting a breaker-bar system; and a fully 3D site on the UK coast, featuring a beach and spit adjacent to a tidal inlet and rocky headland. This phased approach will allow both the process information and the performance of the numerical models to be more easily interpreted.

Innovative techniques will be used in the experiments. Numerical modellers will work interactively with the experiments, at the planning, experiment, and evaluation phases. Participants from national regulatory authorities will ensure that the project is focused on practical tools for coastal zone management.
