Shallow Water Demultiple

Nonclassical Shallow Water Flows

This paper deals with violent discontinuities in shallow water flows with large Froude number F . On a horizontal base, the paradigm problem is that of the impact of two fluid layers in situations where the flow can be modelled as two smooth regions joined by a singularity in the flow field. Within the framework of shallow water theory we show that, over a certain timescale, this discontinuity ...

Shallow Water Domain Decomposition

Scintillating shallow-water waveguides

We present an analysis of acoustic wave propagation in a random shallow-water waveguide with an energy absorbing sub-bottom, in which deviations of the index of refraction are a stochastic process. The speciic model we study is motivated by the oceanic waveguide in shallow waters, in which the sub-bottom sediment leads to energy loss from the acoustic eld, and the stochastic process results fro...

12: Shallow Water Propagation

Shallow-Water Propagation

(A) For elastic sediments we derived a new PE formulation [1] that unlike any predecessor handles layered environments accurately and efficiently while remaining numerically stable. This formulation, based on different computational variables, can treat range dependent sediments and properly account for energy conservation [2]. We demonstrated additional properties and advantages of the new met...
