On the Turbulence Beneath Finite Amplitude Water Waves

TL;DR

This paper clarifies that the turbulence observed in Babanin and Haus's experiment is consistent with Beya et al.'s findings, challenging previous claims of contradiction and emphasizing the presence of turbulence in finite amplitude water waves.

Contribution

The paper reinterprets experimental results to resolve apparent contradictions regarding turbulence measurements beneath finite amplitude water waves.

Findings

Turbulence was observed in Beya et al.'s experiment.

Results are consistent with Babanin and Haus's measurements.

The supposed contradiction in turbulence observations is resolved.

Abstract

The paper by Beya et al. (2012, hereinafter BPB) has a general title of Turbulence Beneath Finite Amplitude Water Waves, but is solely dedicated to discussing the experiment by Babanin and Haus (2009, hereinafter BH) who conducted measurements of wave-induced non-breaking turbulence by particle image velocimetry (PIV). The authors of BPB conclude that their observations contradict those of BH. Here we argue that the outcomes of BPB do not contradict BH. In addition, although the main conclusion of BPB is that there is no turbulence observed in their experiment, it actually is observed.
