Soliton interaction as a possible model for extreme waves in shallow water
Soliton interaction possible model extreme waves shallow water
2009/11/12
Interaction of two long-crested shallow water waves is analysed in the framework of the two-soliton solution of the Kadomtsev-Petviashvili equation. The wave system is decomposed into the incoming wav...
Harmonic Generation of Shallow Water Waves Over Topography
Harmonic Generation Shallow Water Waves Topography
2009/4/3
We investigate the reflection and nonlinear interaction between the first and second harmonics of a two-dimensional Boussinesq wavetrain. Effects of topography are included, the depth departing from a...
Theory of Steady Wind-Driven Currents in Shallow Water with Variable Eddy Viscosity
Steady Wind-Driven Currents Shallow Water Variable Eddy Viscosity
2009/3/24
A theory is given for steady wind-driven currents in shallow water (friction depth comparable to total depth) in which the vertical eddy viscosity varies linearly with depth, from zero at the bottom t...
A shallow-water beta-channel model was used to carry out numerical experiments with cyclonic and anticyclonic disturbances of various strengths. The model is inviscid, so fluid elements conserve poten...
General Spectral Computations of the Nonlinear Shallow Water Tidal Interactions within the Bight of Abaco
Bight of Abaco iterative frequency–time domain finite element
2009/1/4
An iterative frequency–time domain finite element tidal circulation model is applied to the Bight of Abaco in the Bahamas to study the nonlinear interactions that occur between the various astronomica...
Dynamical Properties of Error Statistics in a Shallow-Water Model
model information data information Shallow-Water Model
2008/12/19
Numerical ocean diagnoses and predictions rely on two types of information: model information and data information. Sequential estimation theory shows that the most probable state is a linear combinat...
Interannual Sea Level Variations in the Tropical Indian Ocean from Geosat and Shallow Water Simulations
Sea Level Variations Indian Ocean Shallow Water Simulations
2008/12/19
Sea Level variations of the Indian Ocean north of 20°S are analyzed from Geosat satellite altimeter data over April 1985–September 1989. These variations are compared and interpreted with numerical si...

2008/12/10
This paper examines the results of assimilating Geosat sea level variations relative to the November 1986–November 1988 mean reference, in a nonlinear reduced-gravity model of the Indian Ocean. Data h...
Surface Wave Propagation in Shallow Water beneath an Inhomogeneous Ice Cover
Surface Wave Propagation Shallow Water Inhomogeneous Ice Cover
2008/11/26
The scattering of flexural–gravity waves in a layer of shallow fluid beneath an ice cover with irregularities is investigated. The irregularities considered are the ice edges, cracks, areas of finely ...
