Abstract

To map the 3D distribution of major hydrologic boundaries in a shallow aquifer near Boise, Idaho, 3D seismicreflection data and multifold, pseudo-3D ground-penetrating-radar (GPR) data were analyzed. The seismic data covered a 75- × 70-m area and imaged horizons from 18 to 150 m deep. The 10-fold, 50-MHz GPR data were acquired on a 20- × 30-m grid using a multichannel GPR system and offsets ranging from 2 m to 20 m. By correlating the well-resolved GPR depth image with a clayaquitard seismic reflection, the seismic-velocity model was improved substantially and the accuracy of the final interpretation was improved. The resulting clay-aquitard surface differed by 0.12 ± 0.46 m from the depth to clay measured in wells. By integrating the interpretations of the GPR and seismic data, a 3D map of major hydrostratigraphic boundaries was produced.
