The objective of this project is to quantify the near-field effects of large scale tidal power extraction from the Bay of Fundy by the use of tidal energy extraction devices on the resulting effects of extreme storm events and coastline integrity by implementing a spectral wave model to numerically simulate wave transformation for operational (with turbines) and nonoperational (without turbines) tidal conditions. The predicted current fields for the operational and non-operational conditions were obtained directly from the hydrodynamic modeling of the Bay of Fundy produced by Fisheries and Oceans Canada (Dr. David Greenberg). Time dependent current predictions for the near and far-field models were input directly into the wave spectral model to assess the effects of power extraction on wave transformation. The wave-current modelling analysis was organized into three phases.

• Phase I Seasonal (Non-Storm) Wave Conditions

• Phase II Storm Wave Conditions

• Phase III Extreme Wave Conditions
