Abstract:
An experimental flume study was undertaken to compare water velocity in a bore for a given cross section using an Acoustic Doppler Velocimeter (ADV) and an Electromagnetic Current Meter (ECM). We present a comparison of two among nine elevations above the flume bed. Average and standard deviation of ECM velocities are somewhat higher than those of ADV. However, ADV vertical velocities showed an unexpected trend for the first 4 s after bore ar- rival when turbulent intensity (TI) from ECM varied from 8% to 2%.
