The 1987 Whittier Narrows Earthquake (ML = 5.9) shook two dams, the Puddingstone and Cogswell Dams, which were instrumented as
part of the California Strong Motion Instrumentation Program (CSMIP). The resulting recorded accelerograms provided a valuable
opportunity to investigate and evaluate the accuracy and reliability of conventional geotechnical procedures for evaluation of
dynamic response characteristics of earth and rockfill dams. This paper presents the results of these studies, which provide
insight regarding current techniques for dynamic soil property evaluation and the applicability of one-, two- and three-dimensional
analytical procedures to evaluation of the dynamic response of these types of dams.
