f FULL WAVEFIELD SEISMIC ANALYSIS BENEATH THE A.V. WATKINS DAM, UTAH

A reliable measure of seismic properties as a function of depth is important to the Bureau of Reclamation’s comprehensive and accurate appraisal of site response (ground motion and acceleration) along specific segments of A.V. Watkins Dam in Box Elder County, Utah. A series of seismic data sets were acquired along coincident profile lines at the downstream toe of A.V. Watkins Dam. Three distinctly different surveys, each tailored to a different portion of the wavefield, were optimally acquired and processed. Two three-quarter-mile-long high-hazard portions of the embankment were targeted for this study.
