C004 CAVITY DETECTION USING SEISMIC REFRACTION TOMOGRAPHY: CAN IT BE DONE? J. SHEEHAN 1 W. DOLL 1 W. MANDELL 2 D. WATSON 3 Abstract 1 1 Battelle 105 Mitchell Rd Suite 103 Oak Ridge TN 37830 USA 2 US Army Environmental Center 3 Oak Ridge National Laboratory We are using synthetic models and field data to evaluate the performance of seismic refraction tomography codes for cavity detection. Two-dimensional models have been created and used to generate synthetic travel-time data for tomography analysis. The results of this analysis suggest that the presence of a cavity can sometimes be determined but the
