Present GEK (Geomagnetic Electrokinetograph) theory is extended
to include internal waves of the lowest mode. The predicted
towed electrode GEK signal is determined to second-order for long-crested
internal waves in a finite but deep ocean. The analysis includes
the determination of GEK signatures for small amplitude and
finite amplitude interfacial...
Random waves are often expressed as a mathematical superposition
of an infinite number of sinusoidal components. The mean square spectral
density of the water surface elevation is often called the wave spectrum.
The zero upcrossing wave heights usually have a Rayleigh probability
distribution. However, the design wave concept is still...
Theoretical breaking criteria for progressive surface gravity
waves are examined, and laboratory and field experiments concerned
with breaking waves are reviewed with respect to the testing of these
breaking criteria. The measurements of Komar and Simmons are
presented here for the first time. Only three theoretical breaking
criteria have been...
Sound waves are very convenient for the investigation of
all wave phenomena with the exception of polarization. They are
particularly useful in connection with microwaves because the
latter's wave length can be easily duplicated with sound waves,
making it possible to obtain the same diffraction pattern for
both when confronted...
This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data...
A perfectly matched layer (PML) is widely used to model many different types of wave propagation in different media. It has been found that a PML is often very effective and also easy to set, but still many questions remain.
We introduce a new formulation from regularizing the classical Un-Split...
