    Abstract

    The tomographic inversion of boundary measurements permits determining the spatial distribution of a material property within a soil mass. The most common geotomographic setup for wave-based measurements (mechanical or electromagnetic) consists of two arrays of transducers, one with sources and the other with receivers. The separation between the arrays and the number of sources and receivers have to be determined for every new field condition in order to satisfy resolution requirements in view of physical processes and mathematical constraints. The adequate design of a geotomographic study maximizes the amount of information gathered in the field, renders the maximum possible resolution within the physical constrains associated with field conditions and the available instruments, and prevents unnecessary measurement duplication.
