Shoaling and Breaking of Random Wave Trains: Spectral Approaches
We describe recent efforts to develop a model to predict the evolution of the spectra of random ocean waves shoaling and breaking on a natural beach. A model based on the full Euler equations...

Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...

Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...

The Effect of Wave Grouping on the Characteristic Wave Height
Wave data from two field stations and from the laboratory tests have been analyzed. The groupiness factor is used to categorize the wave data for the discussion of the correlation between...

Taylor-Galerkin Method for Wind Wave Propagation
Recently Taylor-Galerkin method has been used to successfully solve advection-dominated flow problems. This method performs quite well in reducing numerical dissipation and numerical dispersion...

Intermittent Kinematics for Nonlinear Random Waves Near Ocean Surface
Taking into account the fluctuations of the free surface for points in the vicinity of the still water level, this study analytically calculates the first four moments of wave velocity...

Quantitative Stereology of Concrete Microcracking
Stereological methods enable extrapolation of quantitative microcrack characterization from two dimensions to three dimensional space. However, because these quantifying techniques are...

Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...

Wavelet Transform Analysis of Several Transient or Nonstationary Phenomena in Engineering Mechanics
Several examples of the use of a wavelet transform in the analysis of transient events in mechanical systems are provided. The transform has the advantage over other transient analysis...

Complementary Potentials of Finite Elasticity
