Shallow-Water Propagation

چکیده
(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 method [3], including results for seismic sources and for complex environmental variations. We showed significant propagation effects of causal dispersion that arises from frequency-dependent attenuation [4] for some broadband signals in elastic sediments.

متن کاملLong-range propagation of finite-amplitude acoustic waves in an ocean waveguide
A hybrid method coupling nonlinear and linear propagation codes is used to study the nonlinear signature of long-range acoustic propagation for high-amplitude sources in an ocean waveguide. The differences between linear and nonlinear propagation are investigated in deep and shallow water environments. The spectral reshaping that occurs in nonlinear propagation induces two main effects: in shal...

متن کاملDerivation of asymptotic two-dimensional time-dependent equations for ocean wave propagation
A general method for the derivation of asymptotic nonlinear shallow water and deep water models is presented. Starting from a general dimensionless version of the water-wave equations, we reduce the problem to a system of two equations on the surface elevation and the velocity potential at the free surface. These equations involve a Dirichlet-Neumann operator and we show that all the asymptotic...
