Shallow-Water Wave
Shallow-Water Wave : Also called: long wave, Lagrangian wave: An ocean wave whose length is sufficiendy large compared to the water depth (i.e., 25 or more times the depth) that the following approximation is valid: c = Jg~~h , where c is the wave velocity, g the acceleration of gravity, and h the water depth. Thus, the velocity of shallow-water waves is independent of wave length L. In water depths between (1/2)L and (1/25)L it is necessary to use the more precise expression: c = VC?L/2;r)[tanh (lizhIL)}.. See: Deep-Water Waves, Gravity Wave. N.B.
