Abstract

This work presents the first numerical simulations of the long-term evolution of doubly-periodic short-crested wave instabilities, which are the simplest cases involving the three-dimensional instability of genuinely three-dimensional progressive water waves. The simulated evolutions reveal qualitative differences from well-known two-dimensional descriptions, resulting in a permanent transfer of energy to the lower unstable side-band, even with relatively low initial steepness.
