Talk:Shallow water equations
|WikiProject Physics / Fluid Dynamics||(Rated Start-class, Mid-importance)|
I have suppressed a link in this page to the topic "Shallow Water and Waves". The reason why, altough this may seem disturbing, is that both topics are not related one to the other. Shallow water equations are based on the fact that the wave length of the phenomenon they are supposed to model is much bigger than the depth of the river/lake/ocean where the phenomenon takes place (I'll try to had a brief comment about this). Tides are a good example of a valid use of shallow water equations on any case because the wave length of tides is always much bigger than the depth, even in a very deep ocean. A very deep ocean is actually "shallow" from the point of view of tides. The page "Shallow Water and Waves" refers to high frequency breaking waves such as the ones used for surfing, which is the exact contrary of phenomenon that can be modeled with shallow water equations.

Hello Shallow Water;
Very nice, concise article. I believe that there are some typos in the equations that could be easily fixed. The first three equations have eta where I believe you meant h = H + eta, the layer thickness. I would write the sixth equation in the material derivative form, also.
The recently created entry 1-D Saint Venant equation is a duplicate/extension of the existing entry Shallow water equations. Both pages should be merged, so that users find the information about the SV/SW equation collected on one page. — Preceding unsigned comment added by Pia novice (talk • contribs) 12:05, 25 July 2013 (UTC)
