The thesis presents the development, implementation and results of two series of experiments, at large and small scale, for the study of surface gravity waves. A number of measurement techniques are developed and implemented to capture space and time... Read More about Laboratory scale experiments with water surface waves.

Non-stationary regimes of surface gravity wave turbulence (2013)
Journal Article

We present experimental results about rising and decaying gravity wave turbulence in a large laboratory flume. We consider the time evolution of the wave energy spectral components in ω- and k-domains and demonstrate that emerging wave turbulence can...

Gravity wave turbulence in a large flume (2013)
Book Chapter
Bedard, R., Nazarenko, S., & Lukaschuk, S. (2013). Gravity wave turbulence in a large flume. In Advances in Wave Turbulence (187 - 237). World Scientific

We overview past and new experimental results on gravity wave turbulence obtained at The Deep flume facility in Hull. The relatively large size of this flume, 12m × 6m × 1.5m, allows us to study the pure gravity waves without being concerned with mod... Read More about Gravity wave turbulence in a large flume.

Statistics of surface gravity wave turbulence in the space and time domains (2009)
Journal Article

We present experimental results on simultaneous spacetime measurements for the gravity wave turbulence in a large laboratory flume. We compare these results with predictions of the weak turbulence theory (WTT) based on random waves, as well as with p...

Gravity wave turbulence in wave tanks: Space and time statistics (2009)
Journal Article

We present the first simultaneous space-time measurements for gravity wave turbulence in a large laboratory flume. We found that the slopes of k and ω wave spectra depend on wave intensity. This cannot be explained by any existing theory considering... Read More about Gravity wave turbulence in wave tanks: Space and time statistics.

Laboratory studies of near-grazing impulsive sound propagating over rough water (2008)
Journal Article

Acoustic impulses due to an electrical spark source (main acoustic energy near 15 kHz) have been measured after propagating near to the water surface in a shallow container resting on a vibrating platform. Control of the platform vibration enabled co... Read More about Laboratory studies of near-grazing impulsive sound propagating over rough water.

Surface tension: Floater clustering in a standing wave (2005)
Journal Article

How do waves affect the distribution of small particles that float on water? Here we show that drifting small particles concentrate in either the nodes or antinodes of a standing wave, depending on whether they are hydrophilic or hydrophobic, as a re...
