There is an energy (and wave action) cascade for weakly nonlinear narow-banded deep water surface waves that lead to (small) waves being annihilated by viscosity (this of course doesn't happen in nature as waves break and dissipate energy over a range of scales). If you're interested in that question you can ask it separately and I can elaborate. Note, $standing$ waves do occur in nature (oppositely traveling waves with the same amplitude and phase) and are thought to be the source of microseisms in the ocean. | |

This has implications to intentionally building regions of destructive interference with a finite number of sources. | |

| Dec 27, 2016 at 11:16 | comment | added | veronika | @Ruslan I am sorry but it was an answer of user Anna V in this site and I don't even remember the question. Though I think it is a clear statetement and I know it from my job, ships try to canclel their own wave by means of a bulbous bow but they partially suceed. | |

In the idealized situation all the kinetic energy get converted into thermal energy, means in chaotic vibrations of the liquids molecules. Since the two incoming waves couldn't be identical (with opposite sign) in reality they couldn't cancel each other out (over going to pure thermal energy) and waves of smaller amplitude appear. | |
