The "Nonlinear wave groups on deep water" has nothing in common with "Nonlinear Schrödinger equation". In the articles quite different equations are considered, and waves of quite different behaviour are described. The differences are clearly explained in the "Nonlinear wave groups on deep water". — Preceding unsigned comment added by Slokenberg (talk • contribs) 12:02, 3 September 2017 (UTC)Reply

Hello Slokenberg, Wikipedia is an encyclopedia and "An encyclopedia or encyclopaedia is a reference work or compendium providing summaries of information from either all branches of knowledge or from a particular field or discipline." The parts of the article describing nonlinear wave groups either refer to the nonlinear Schrödinger equation, or are references to work by I.M. Mindlin, which are either not often cited (Mindlin, 2004) or arXiv preprints (Mindlin, 2014). These are either not reliable secondary sources on the subject or are not of due weight (in terms of scientific consensus on the subject) to be included in the article. Further see all the mentioned issues in the lead.

Until cast into a more balanced -- conforming scientific consensus and main approaches to the subject -- and more readable form, to my opinion a redirect to the nonlinear Schrödinger equation (NLS) is a reasonable workaround (since most literature on nonlinear deep-water wave groups is on the NLS and its solutions). -- Crowsnest (talk) 18:55, 3 September 2017 (UTC)Reply
