Single-Beam Acoustic Doppler Profiler and Co-Located Acoustic Doppler Velocimeter Flow Velocity Data

Simultaneous measurements with 3D PIV and Acoustic Doppler Velocity Profiler

Simultaneous velocity measurements were taken using Particle Image Velocimetry (PIV) and an Acoustic Doppler Velocity Profiler (ADVP) in a sharp open-channel bend with an immobile gravel bed. The PIV measures 3D velocity vectors in a vertical plane (~40cm x 20cm) at a frequency of 7.5 Hz, whereas the ADVP measures 3D velocity vectors in a vertical profile with a frequency of 31.25 Hz. The paper...

Operating an Acoustic Doppler Current Profiler aboard a Container Vessel

Since October 1992 an acoustic Doppler current profiler (ADCP) has been in near-continuous operation on board a 118-m-long container vessel, the container motor vessel Oleander, which operates on a weekly schedule between Port Elizabeth, New Jersey, and Hamilton, Bermuda. The ADCP collects information on currents from the surface to depths as great as 404 m depending on zooplankton concentratio...

Analysis of Open-channel Velocity Measurements Collected with an Acoustic Doppler Current Profiler

Acoustic Doppler Current Profilers (ADCP’s) are easier to apply and more rapidly collect velocity data than traditional current-meter instruments. However, flow discharge estimates in natural rivers and canals based on ADCP measurements rely on extrapolations of the measured velocity profiles into the unmeasured zones of the flow. Furthermore, the accuracy and reliability of ADCP’s have not bee...
