• Secondary flow in sharp open-channel bends (2004, background): “Detailed information on its working principle, its experimental uncertainty and a comparison with other velocity meters (see also the Appendix) can be found in Lemmin & Rolland (1997), Hurther & Lemmin (1998, 2001), Blanckaert & Graf (2001) and Blanckaert & Lemmin (2004).”
• Double-averaging analysis and local flow characterization of near-bed turbulence in gravel-bed channel flows (2009, methodology): “In order to reduce the Doppler phase noise contribution linked to the random stationary backscattering process, the imaginary part of the auto-correlation function of the complex Doppler signal is calculated (Serafin & Lhermitte 1984; Hurther & Lemmin 2001, 2008).”
• Measurements of Turbulence at Two Tidal Energy Sites in Puget Sound, WA (2012, background): “…velocities are flows resulting from external forcing, such as wind- and density-driven (estuarine) flows [19], or surface-wave orbital velocities, which decay beneath the surface as , where the wave number is from linear theory, is the distance above the seabed, and is the total water depth [20].”
• Means of noise reduction in acoustic turbulence measurements (2006, methodology): “Hurther and Lemmin (2001) have proposed a direct correction method, referred to as the HL method in this paper, by which most of the noise in turbulence measurements with four-receiver ADV instruments can be eliminated.”
• Mean Flow and Turbulence in Open-Channel Bend (2001, methodology): “This is of importance since it permits an evaluation and correction for the experimental noise (Hurther and Lemmin 2001).”
• Observations of velocities, sand concentrations, and fluxes under velocity-asymmetric oscillatory flows (2011, methodology): “Its sampling rate was 100 Hz. Detailed velocity measurements from approximately 150 mm above the bed to within the sheet flow layer were conducted with an Acoustic Doppler Velocimeter Profiler (ADVP) [ Hurther and Lemmin, 2001 ].”
