www.fast.u-psud.fr3.8 would be obtained, with all velocities merely being changed to shear wave velocities. However, the more common cases of a fluid-solid interface or of two solids separated by a thin film of lubricant would prevent transmission of shear waves across the interface. The case of waves normally incident on a layer sandwiched between two media is the
The Seismic Wave Equation
igppweb.ucsd.edu3.1 Introduction: The Wave Equation To motivate our discussion, consider the one-dimensional wave equation ∂2u ∂t2 = c2 ∂2u ∂x2 (3.1) and its general solution u(x,t) = f(x±ct), (3.2) which represents waves of arbitrary shape propagating at velocity cin the positive and negative xdirections. This is a very common equation in physics and ...

Basic Concepts of Kinematic-Wave Models - USGS
pubs.usgs.govKinematic-wave theory describes a distinctive type of wave motion that can occur in many one-dimen sional flow problems (Lighthill and Whitham, 1955, p. 281). The theory is described in this report as an approximation of dynamic-wave theory applied to water-routing problems. The purpose of this report is to provide a basic refer
