Talk:Shallow water equations

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)
- Looks like there's no consensus, so I'm removing the tag for now. KJ Discuss? 23:59, 24 August 2014 (UTC)
- I agree that the articles should be merged – the 1-D SV equation is merely a special case of the SWE, with the same physical interpretations. --jftsang 21:22, 15 June 2015 (UTC)
File:Shallow water waves.gif to appear as POTD
Hello! This is a note to let the editors of this article know that File:Shallow water waves.gif will be appearing as picture of the day on May 3, 2015. You can view and edit the POTD blurb at Template:POTD/2015-05-06. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 23:42, 14 April 2015 (UTC)
