Wave scattering by undulating bed topography in a two-layer ocean
two-layer ocean wave scattering bottom undulations reflection transmission coefficients
2011/9/13
The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there e...
Two-layer Exchange in an Estuary Basin, with Special Reference to the Baltic Sea
Two-layer Exchange Estuary Basin Baltic Sea
2009/3/26
Stationary and transient states of a two-layer fjord-type estuary are discussed analytically. The forcing functions are the outer salinity S0, the fresh-water supply qf, and a meteorologically forced ...

2009/3/24
A two-layer model is constructed for wind-driven flow over topography in a closed polar basin where the variation of Coriolis force with latitude is negligible. The model equations are reduced using s...
The problem of water waves propagating over a mud bottom, characterized as a laminar viscous fluid, is treated in several ways. First, two complete models are present, each valid for different lower (...
