Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power

Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy. Flow measurements were made using a broadband 600 kHz acoustic Doppler current profiler (ADCP) sampling at nearly 2 Hz, and two single-point sensors: an acoustic Doppler velocimeter (ADV) sampling at 1 Hz, and a time-of-flight velocity sensor (MAVS) sampling at 12 Hz.
