Using Geophysics to Assess the Condition of Small Embankment Dams
Abstract
The U.S. Army Engineer Research and Development Center (ERDC) Geotechnical and Structures Laboratory conducted a program of technical and archival research to document current knowledge of indirect seepage detection and methods for monitoring the conditions within small embankment dams. This report documents current methods used to determine conditions within embankment dams by indirect means and provides guidance on determining which methods will most likely succeed at various sites. The report includes a review of current indirect geophysical technologies used in seepage investigations with emphasis on small-sized earthen dams (<7,500 m long, <40 m high). A summary of state-of-the- art equipment, principles of operation, and field procedures is also presented, followed by the results of a September 2003 geophysics-based investigation of seepage and conditions within Clearwater Dam in southeastern Missouri. The report concludes with recommendations for future development of the most promising technologies to be used for seepage detection and assessing the condition within embankments.
