Physical processes in the world's oceans span an enormous range of spatio-temporal scales, from ocean circulation at the global scale down to dissipation and mixing at the centimeter scale. It is impo...
Propagating and evanescent internal waves in a deep ocean model
Propagating evanescent internal waves deep ocean model
2012/2/28
We present experimental and computational studies of the propagation of internal waves in a stratified fluid with an exponential density profile that models the deep ocean. The buoyancy frequency prof...
Three-dimensional hydrodynamic model of concrete tetrahedral frame revetments
concrete frame tetrahedrons numerical simulation drag lift
2011/9/13
Revetments of concrete frame tetrahedrons are being used more and more in river engineering in China. Due to their complex geometry, it is difficult to measure the velocity fields inside them using tr...
Fractal trajectories in a numerical model of the upper Indian Ocean
Fractal trajectories numerical model upper Indian Ocean
2009/11/16
A wind-driven numerical model of the Indian Ocean is used to examine the horizontal statistics of hundreds of passive tracers spread evenly over the model domain. The distribution covers several dynam...
Nonequilibrium plankton community structures in an ecohydrodynamic model system
Nonequilibrium plankton community structures ecohydrodynamic model system
2009/11/16
Due to the local and global impacts of algae blooms and patchiness on water quality, carbon cycling and climate, models of plankton dynamics are of current interest. In this paper, the temporal and sp...
A fractal model for the sea state bias in radar altimetry
fractal model sea state bias radar altimetry
2009/11/13
The Kirchhoff approximation is used to determine the sea state bias in radar altimetry. A weakly nonlinear model of the sea waves is used to derive the joint moments of two different points separated ...
Permanent bedforms in a theoretical model of wave-sea-bed interactions
Permanent bedforms theoretical model wave-sea-bed interactions
2009/11/12
The interaction between sea waves and a deformable sea-bed is studied with a simple two-layer model in which the upper-layer fluid is inviscid and the lower-layer fluid is bi-viscous to account for no...
Scaling statistics in a critical,nonlinear physical model of tropical oceanic rainfall
Scaling statistics critical,nonlinear physical model tropical oceanic rainfall
2009/11/12
Over the last two decades, concepts of scale invariance have come to the fore in both modeling and data analysis in hydrological precipitation research. With the advent of the use of the multiplicativ...
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...
