Intertidal hydrodynamics and basin-scale sediment dynamics in the Minas Basin, Bay of Fundy, and implications for change due to tidal power extraction

Abstract

Minas Basin in the Bay of Fundy has the world’s largest tidal range and exchanges approximately 110 billion tonnes of water twice a day with tidal currents up to 5 ms-1 through Minas Passage, making it an ideal site for tidal power extraction. In this thesis a multi-domain high-resolution hydrodynamic model of Minas Basin is implemented and used to investigate: a) the relative influence of vegetation on flow routing in a macrotidal estuary to develop an understanding of the intertidal hydrodynamics in the natural system; and b) the implications of tidal energy extraction on basin-scale suspended sediment concentrations by simulating in-stream turbines.
