The main objective is to evaluate the storm-scale effect of shore-parallel breakwaters in tidal conditions on coastal morphology using a combination of Q3D morphological computer modelling and new hydrodynamic and morphological data from the Sea Palling site in Norfolk as well as some existing data from UKCRF tests on the Elmer breakwaters. The objectives of the Project are:

1. Incorporate wave-overtopping, porosity and reflection into the Q3D model and test against existing data from the UKCRF collected in the LUPY project;
2. Model the morphodynamic changes in an embayment of the Sea Palling breakwater during individual winter storms using Q3D, a combined hydrodynamic and morphodynamic model;
3. Measure hydrodynamics (waves, tides and currents) in an embayment during two winter seasons to capture storm events;
4. Survey the beach and bathymetry around the breakwaters immediately following storms events
5. Evaluate the efficacy of the Q3D and evaluate its usefulness in modelling storm-scale changes around breakwaters.
