This report documents the results of a geophysical investigation at the Olmsted site of the Ohio River Navigation Project. Surface and subsurface methods consisting of seismic refraction, crosshole, downhole, and uphole testing were performed. Testing was conducted on both sides (Kentucky and Illinois) of the Ohio River with compression and shear wave profiles developed along the center line of the proposed lock and dam and parallel to the river on each side. Data from borehole logs indicated the site consisted of four zones: alluvium, McNairy 1, McNairy 2, and Paleozoic. Stratigraphy and seismic velocities of these zones were determined. The shear wave velocities were obtained for future input to a dynamic analysis of the lock and dam. Keywords: Crosshole seismic testing; Geophysical site investigation; Seismic refraction testing; Dam site investigation; Locks(Waterways); Engineering geology. (edc)
