Multi-Scale Turbulence Measurement in the Aquatron Laboratory

July 2018 – July 2019

This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.

Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions

April 2018 – April 2019

Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).

Turbine Wake Characterization

November 2017 – March 2019

Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays.  In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings.  It is thus desired to not just delineate wake

Testing of Temporal Monitoring Techniques for Benthic Habitat Impacts of Tidal Energy Developments

September 2011 – November 2014

This project tested and developed monitoring procedures for assessing the impact of the placement of in-stream tidal devices (e.g. turbines, cables and other seafloor hardware) on the seafloor environment.

Implications of Tidal Energy Extraction on Sedimentary Processes within Shallow Intertidal Environments

September 2011 – April 2014

This project assessed the implications of tidal energy extraction on sedimentary processes within shallow inter-tidal ecosystems.

Impacts of Tidal Energy Extraction on Sediment Dynamics in Minas Basin, Bay of Fundy

February 2010 – December 2012

Researchers developed a numerical hydrodynamic and sediment transport model for Minas Basin in the Bay of Fundy, focusing on the sediment dynamics of the tidal inlets and flats.

Tidal Energy Resource Assessment Map for Nova Scotia

March – October 2012

This project used numerical simulations and theoretical calculations to predict not only the power that can be extracted from the flow through a passage but also the reduction in flow through the passage.

Effects of Energy Extraction on Sediment Dynamics in Intertidal Ecosystems of the Minas Basin

January 2010 – May 2012

This project assessed how the dynamics of sedimentation change when energy is extracted from a macro-tidal system. The differences in tidal prism and energy between neap and spring tidal cycles were used as a proxy for energy extraction by in-stream tidal power devices.

Assessing the Far Field Effects of Tidal Power Extraction on the Bay of Fundy, Gulf of Maine and Scotian Shelf

January 2010 – April 2012

The Bay of Fundy and Gulf of Maine system has a natural resonant period very close to the main semi-diurnal lunar tide. This results in the world’s highest tides and strong tidal currents in the Bay of Fundy, particularly in the Minas Channel and Minas Basin.
