Comparing MASW2D Vs profiles and shear-wave reflection profiles
is a meaningful exercise because the two methods exhibit certain similarities
including: 1) the Rayleigh wave from MASWhas a propagation
velocity (Vr) very close to the Vs as Vr = 0.87 to 0.96 Vs (Viktorov,
1967), depending on the value of the Poisson's ratio, 2) both methods
require a source to generate seismic energy andmulti-channel receivers
to record the returned energy to the surface, and 3) shear-wave reflection
profile consists of traces, each of which represents the physical
properties of the earth's material along the passage traveled by the
seismic waves from the source to the receivers. Similarly, MASW 2D Vs
profiles assemble multiple 1D Vs profiles, each of which represents
average velocities of the volume of the earth beneath the receiver array
