Shallow water wave slowed down by change of depth
Summary[edit]
.gif&action=edit§ion=1){kind=link}
| Description |
English: The velocity of propagation of a sea wave depends on the depth of the water: the shallower the water the slower the wave. So if the depth reduces the wave will "accumulate" (like in a traffic jam).
Notice that this is just the propagation of a gaussian pulse with the shallow water dispersion relation, not a solution of the 1D Saint-Venant equations. |
