Shallow
and Deep Water
•“Shallow” in this lecture means that the depth of the
fluid layer is small compared with
the horizontal scale of the perturbation, i.e., the horizontal scale is large compared with the
vertical scale.
•Shallow water gravity waves are the ‘long wave
approximation” end of
gravity waves.
•Deep water gravity waves are the “short wave
approximation” end of
gravity waves.
•Deep water gravity waves are not important to
large-scale motions in
the oceans.
