Abstract: Coherent Doppler sonar provides a powerful tool for probing boundary layer flows under field and laboratory conditions. However, velocity profiling applications of this technique are complicated by characteristic velocity ...

Abstract: Computationally simple criteria for the identification of spurious Doppler profiler velocity estimates are described and evaluated. Their effectiveness is determined by changes in the confidence intervals and mean values ...

Abstract: prototype wideband coherent Doppler profiler (MFDop) was tested for measuring bedload velocity of different gravel and coarse-sand-sized fractions (d = 1?32 mm) in the laboratory. The sediment was spread out on a smooth-surface ...
