Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using observations from the central Oregon coast to identify the wave-driven return flow present and quantify the potential bias of wind-driven across-shelf exchange by unresolved wave-dr...

The influence of an underlying current on three-wave interactions of capillary water waves is studied. The fact that in irrotational flow resonant three-wave interactions are not possible can be invalidated by the presence of an underlying current of constant non-zero vorticity. We show that: 1) wave trains in flows with constant non-zero vorticity are possible only for two-dimensional flows, 2...

Asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.From these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. Instability condition is obtained and g...

Question has been raised about the possible impact sea state which may have on the performance of the Joint Direct Attack Munition (JDAM) Assault Breaching System (JABS) in the very shallow water (VSW) regime (depth up to 40 ft). We investigated the wave effect on underwater bomb trajectory. We will present: (1) development of a new version of the NPS 6 DOF model with the capability to predict ...

Nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. These types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. In the current study, the performance of floating breakwater (FBs) under regular waves was studied using the physical modeling method. For the mode...

It is shown that the dielectric properties of interaction site models of polar fluids can be investigated in computer experiment using not only the charge fluctuations but also correlations corresponding to a current of moving charges. This current can be associated with a generalized dynamical polarization or separated into electric and magnetic components. The first approach deals with the di...

The underlying approach combines field observations of wave-induced bubbles and ambient noise in the top meter of the marine boundary layer with models for wave noise generation. The field studies are organized around a bubble plume sensing system, consisting of an optical bubble counter, a depth sensor, a hydrophone and an underwater video camera. The plume sensing system is mounted on a surfa...
