Random Breaking Waves – Horizontal Seabed
Coastal Engineering 1986, 1986 According to wave theories the depth limited wave height over a horizontal seabed has a wave height to water depth ratio (H/d) of about 0.8. Flume experiments with monochromatic waves over a horizontal seabed have failed to produce H/d ratios greater than 0.55. However designers still tend to use H/d 0.8 for their design waves.

Random walk of solitary and shock waves in nonlocal disordered media
New Journal of Physics, 2013 We study the random walk of solitons and characteristic lines of shock fronts in the presence of disorder for the one-dimensional nonlinear Schrödinger equation in Kerr-like media. We analyze the interplay of nonlocality and randomness, and the way their

Spin waves in a Mattis random magnet [PDF]
Journal of Physics C: Solid State Physics, 1977 It is shown that a random Heisenberg magnet characterized by H=1/2 Sigma iJij xi i xi jSi.Sj, where Jij is a fixed function of the separation of sites i and j but the xi i are randomly +or-1, can sustain well defined long-wavelength spin waves with an antiferromagnetic-like linear dispersion.

VELOCITIES UNDER PERIODIC AND RANDOM WAVES
Coastal Engineering Proceedings, 1974 Using the linear approximation for predicting velocities under periodic water waves, relationships are established between the velocity spectrum and the surface elevation spectrum for three-dimensional waves. The two dimensional forms of these relationships are used for comparison with velocity and elevation spectra measured in a laboratory wave tank ...
