Measuring Velocity and Shear Stress over Dunes with Acoustic Doppler Profiler
Publisher: American Society of Civil Engineers
Abstract: This study evaluates the use of an acoustic Doppler profiler (ADP) for measurement of velocity profiles over dunes in an estuary. The ADP can be deployed from a moving launch and provides three-dimensional velocity profiles ...
Turbulence Modulation and Particle Velocities over Flat Sand Beds at Low Transport Rates
Publisher: American Society of Civil Engineers
Abstract: The presence of sand moving at low transport rates over a flat bed modulates the production of turbulence when compared to clearwater flow at similar mean flow conditions. Phase Doppler anemometry is used to discriminate ...
