Abstract
A two-dimensional hydrodynamic model is coupled with a suspended and bedload sediment transport model within the Thetis coastal ocean modelling framework. In investigating the effect of sediment transport on turbine array performance, we consider two artificial scenarios of 16 turbines deployed in aligned and staggered layouts to explore the impact of morphodynamics on power conversion. An optimisation algorithm is then applied to improve the position of turbines to maximize power output. Comparing this optimisation for a case with and without sediment transport we study the effect of morphodynamics on optimal layouts. The results show that sediment transport can significantly influence the performance of the aligned layout turbine array. As for the layout optimisation process, the inclusion of sediment transport makes little difference to the final results, while the computational cost becomes substantial when including the sediment model within the optimisation, even for a steady state case.
