Abstract:

A geophysical study was performed using the self potential SP method. This study was directed toward detection and delineation of possible seepage paths through the embankment andor left abutment at Center Hill Dam, Tennessee. Studies were done before and after remedial work at the dam. The initial study indicated several possible seepage zones which are interpreted as areas of low SP measurements. The follow-up survey conducted after completion of the remedial work could not conclusively detect any changes in the SP anomalies found in the initial study. Nevertheless, there is a significant low SP anomaly on the downstream left abutment, near the embankmentdam interface. Further studies are recommended to better characterize the SP environment at this site through long-term monitoring to see if the SP anomalies are related to pool level, weather, time, etc., so that better and more definitive conclusions can be made.
