Nonlinear effects in surface gravity waves
… of energy within a continuous spectrum of water waves is considered.� Using a transfer equation derived by LonguetHigg: ins (1975) for narrow spectra, and choosing suitable simple forms for these spectra, we make accurate evaluations of the energy transfer rate as a function of the two …

The interaction of periodic surface gravity waves with slowly varying water currents
The governing equations for interactions between surface gravity wavetrains and slowly-varying water currents are derived and the incorporation of Vocoidal water wave theory into this framework is discussed. The emphasis throughout is on the derivation of the general form of the governing equations …

Cross-shelf circulation and momentum and heat balances over the inner continental shelf near Martha's Vineyard, Massachusetts
… temperature, density, and bottom pressure; surface gravity waves; wind stress; and heat flux between the ocean and atmosphere during 2001-2007. When waves are small, cross-shelf wind stress is the dominant mechanism driving cross-shelf circulation. The along-shelf wind stress does not drive …

Underwater sound radiation from single large raindrops at terminal velocity: the effects of a sloped water surface at impact
… velocity raindrops striking a smooth water surface create oscillating bubbles that radiate significant underwater sound energy. Those studies identified two diameter ranges that produce bubbles: small drops (.8-1.1 mm diameter) which produce bubbles by one mechanism and large drops (2.2-4.6 …

Seafloor ripples created by waves from Hurricane Ivan on the west Florida shelf
… Ripple prediction requires information about surface gravity waves and sediment grain size. The most reliable offshore wave field available was created with Wavewatch III by Naval Postgraduate School scientists. These waves were inputted into Delft3D WAVE, incorporating the nearshore wave …

A new numerical method for the problem of nonlinear long-short wave interactions
… the problem of nonlinear interactions of free-surface gravity waves. More specifically, this study addresses the case of wave interactions of short waves ridding on longer waves up to second order of nonlinearity M. The study of the nonlinear interactions between long and short waves is an …

A numerical study on the propagation and interaction of strongly nonlinear solitary waves
… a strongly nonlinear long wave model for surface gravity waves propagating in both one and two horizontal dimensions. This model often referred to as the Su-Gardner or Green-Naghdi equations can be derived from the Euler equations under the assumption that the ratio between the …

Laboratory scale experiments with water surface waves
… 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 evolution of waves on a water surface in gravity, gravity-capillary and capillary ranges with the purpose to study the statistics of …

Sediment Resuspension in a Microtidal Estuary: Causative Forces and Links with Algal Blooms
… in estuaries typically results from wind-driven waves, tidal currents, or wind-driven currents. Results from this study found maximum wave orbital velocities (U<sub>bm</sub>) to be an order of magnitude less than current velocities (U<sub>c</sub>), however, periods of elevated U<sub>bm</sub>, …

A Theoretical and Numerical Study of Turbulent Wind-Wave Interaction
… simulation (LES) of airflow over water waves and linear analysis, we discover that in certain scenarios, the interactions between turbulent wind and waves can be explained by linear theory without pursuing turbulence stress models. In this thesis, we present two of these scenarios. The …

Very low frequency seismo-acoustic noise below the sea floor (0.2-10 Hz)
… of microseisms is nonlinear interaction of surface gravity waves at the sea surface. Though this source relationship is generally accepted, the actual processes by which the wave generated acoustic noise in the water column couples and propagates to and along the sea floor are not well …
