| Abstract | The North Shore of Prince Edward Island (PEI) is a sandy, multi-barred coast with limited fetch in most directions but open to the Gulf of St. Lawrence for several hundred kilometres to the north. In
the fall and winter, storms tracking northwards across PEI and into the Gulf can bring sustained storm waves which generate currents capable of transporting sand in both the along- and across-shore directions. Mike21 is a commercially available
combined wave, hydrodynamic and sand transport model that may be utilised to improve understanding of contemporary sand transport and possible implications of changing climate in the Brackley Bight area of the North Shore. This manuscript describes
the development of a Mike21 model domain and optimal configurations of the Mike21 Spectral Wave, Hydrodynamic and Sand Transport modules appropriate to the study area. The sensitivities of several parameters in each module are tested. The Spectral
Wave and Hydrodynamic modules are sensitive to estimates of bed roughness with optimal values considerably lower than published semi-empirical estimates. The Sand Transport module is sensitive to the input sediment transport tables and estimates of
the maximum amount of vertical bed level change per day. Simulation of a 4-day moderate northeasterly storm is conducted and the results are compared to currents, waves, and tides measured by S4 current meters and the instrumented seabed lander RALPH
during a sediment transport experiment in 1999. The model successfully simulates storm waves and currents and provides reasonable estimates of the amount and patterns of sediment transport. |
