Bayesian Approach to UXO Site Characterization with Incorporation of Geophysical Information
Abstract
UXO site characterization approaches are developed to assist decision makers in determining where additional characterization efforts need to be expended and where additional characterization is not effective. These decisions are based on limited transect data and require that without 100 percent site characterization there is a finite probability of leaving some UXO behind. One theoretical limitation of geostatistical approaches to estimation is the assumption that sample data exist in an unbounded domain. Contiguous transect data because of their close proximity to each other violate this assumption and can produce unwanted results in the estimates. The extent of these unwanted results are checked for a variety of transect sample designs on three simulated sites and the results show that the effects of the finite domain associated with transect data are negligible and traditional geostatistical estimation techniques can be applied.
