during a flow event with a peak of 15.5 m 3 s − 1 . Instrument LTH2A was secured
to the bed immediately downstream from a large wood structure, while instrument
LTH2B was secured to the bed along the same cross-section but at the centerline of
the base flow channel. Measured velocities were noisy due to turbulent fluctuations,
acoustic interference fromfloating and suspended trash and debris, and factors internal
