Abstract: This report describes the application and benchmarking of the Thetis coastal ocean model for tidal modelling, and makes use of a test case based upon the English Channel. Comparisons are made between model predictions and tide gauge data at a number of locations across the English Channel. A preliminary investigation of the impact of mesh resolution and bathymetry data is given. A demonstration is also provided of Thetis’s ability to use adjoint technology to optimise model predictions through the assimilation of observational data. In the example presented here the bottom friction field is optimised to provide an improved match between the model results and tide gauge data. This adjoint based optimisation capability may also be used to optimise the location, size and design of tidal power generation schemes.
