Seismic Imaging of UXO-Contaminated Underwater Sites

Abstract

Two- and three-dimensional numerical modeling was conducted to evaluate the performance of source-receiver arrays to "detect" and "locate" UXO in littoral environments. While the 2-D investigations were based on finite difference (FD) modeling, the 3-D study used an analytical solution for the scattering of elastic waves by spherical objects to model the interaction of waves with UXO. The forward modeling or "detection" phase generated seismic data that reveal the presence of UXO in the subsurface.
