TL;DR: In this paper, the surface elevation of long crested waves characterized by Jonswap spectra with random phases was studied in deep water conditions in one of the largest wave tank facilities in the world.

TL;DR: Two independent, large scale experiments performed in two wave basins of different dimensions show that the probability of the formation of large amplitude waves strongly depends on the directional properties of the waves.

TL;DR: In this paper, a wave basin experiment has been performed in the MARINTEK laboratories, in one of the largest existing three-dimensional wave tanks in the world, to investigate the effects of directional energy distribution on the statistical properties of surface gravity waves.

TL;DR: Experimental evidence that the tail of the probability density function for wave height strongly depends on the Benjamin-Feir index and the fact that large-amplitude waves in random spectra may result from the modulational instability is confirmed.

TL;DR: In this article, the authors studied the dynamics of mechanically generated waves propagating over an oblique current in partial opposition, and found that wave steepness triggered modulational instability on otherwise stable wave trains and hence induced the development of very large amplitude waves.
