Bore formation,evolution and disintegration into solitons in shallow inhomogeneous channels
Bore formation evolution disintegration shallow inhomogeneous channels
2009/11/12
The propagation of nonlinear surface waves in channels of smoothly variable in space cross section is studied theoretically and by means of numerical computations. The mathematical model describing wa...
Coastal-Trapped Waves in Continuously Stratified Channels. Part I：Numerical Description of Behavioral Properties
coastal-trapped wave Coastal-Trapped Waves Stratified Channels
2009/1/5
A numerical model which solves the linearized, quasi-geostrophic potential vorticity equation is used to describe free subinertial coastal-trapped wave (CTW) properties in channels with variable depth...
Numerical Study of Topographic Wave Reflection in Semi-Infinite Channels
topographic wave reflections Semi-Infinite Channels Numerical Study
2009/1/5
The Potential vorticity equation describing topographic waves is approximately solved using the channel method of Stocker and Hutter. The domain of integration is a semi-infinite channel and models an...

Intermediate Models Slope Flow Fields Barotropic Continental Shelf Numerical Model Solutions
2008/12/30
The study of intermediate models for barotropic continental shelf and slope flow fields initiated in Parts I and II is continued. The objective is to investigate the possible use of intermediate model...
Maximal Exchange in Channels with Nonrectangular Cross Sections
net flow rate Nonrectangular Cross Sections two-layer flows Exchange flow
2008/12/23
The functional formalism of Gill and Dalziel is extended for two-layer flows in nonrectangular cross sections. Exchange flow through channels with a range of different cross sections is investigated i...
Oscillating Barotropic Currents along Short Channels
Oscillating Barotropic Currents Short Channels
2008/10/27
Intuitively, the transport of an oscillating flow in a short channel should be constrained to be approximately the same at all cross sections; that is, the transport is nondivergent. This intuitive co...
Sediment-Driven Downslope Flow in Submarine Canyons and Channels: Three-Dimensional Numerical Experiments
Sediment-Driven Downslope Flow Submarine Canyons Channels Three-Dimensional Numerical Experiments
2008/7/3
The role of submarine canyons and channels in sediment-driven downslope flow (sediment plumes) is examined, using a three-dimensional, rotational numerical model that couples the hydrodynamics and sed...
