Category:Geophysics

2009-08-01T09:39:30Z

Greg2009:

Water waves have many applications in geophysics.

Here is a list of important points.

# Wavelength and frequency of waves are related through the dispersion relation.
# The velocity of a wave phase can differ from the velocity at which wave energy propagates.
# Waves in deep water are dispersive, longer wavelengths travel faster than shorter wavelengths. Waves in shallow water are not dispersive.
# The dispersion of ocean waves has been accurately measured, and observations of dispersed waves can be used to track distant storms.
# The shape of the sea surface results from a linear superposition of waves of all possible wavelengths or frequencies traveling in all possible directions.
# The spectrum gives the contributions by wavelength or frequency to the variance of surface displacement.
# Wave energy is proportional to variance of surface displacement.
# Digital spectra are band limited, and they contain no information about waves with frequencies higher than the Nyquist frequency.
# Waves are generated by wind. Strong winds of long duration generate the largest waves.
# Various idealized forms of the wave spectrum generated by steady, homogeneous winds have been proposed. Two important ones are the Pierson-Moskowitz and JONSWAP spectra.
# Observations by mariners on ships and by satellite altimeters have been used to make global maps of wave-height. Wave gauges are used on platforms in shallow water and on the continental shelf to measure waves. Bottom-mounted pressure gauges are used to measure waves just offshore of beaches. And synthetic-aperture radars are used to obtain information about wave directions.

2009-08-01T09:38:40Z

Greg2009:

== Introduction ==

Linear water waves are small amplitude waves for which we can linearise the equations of motion ([[Linear and Second-Order Wave Theory]]).
It is also standard to consider the problem when waves of a single frequency are incident so that only a single frequency
needs to be considered, leading to the [[Frequency Domain Problem]].
The linear theory is applicable until the wave steepness becomes sufficiently large that non-linear effects become important.

== Equations in the Frequency Domain ==

{{standard linear problem notation}}
[[Variable Bottom Topography]]
can also easily be included.

{{standard linear wave scattering equations}}

The simplest case is for a fixed body
where the operator is <math>L=0</math> but more complicated conditions are possible.

{{incident plane wave}}

{{sommerfeld radiation condition two dimensions}}

{{sommerfeld radiation condition three dimensions}}
