Investigation of Geophysical Methods for Assessing Seepage and Internal Erosion in Embankment Dams: Self-Potential Field Data Acquisition Manual

This field manual is designed to help the user obtain high-quality self-potential (SP) data in support of embankment dam seepage investigations. The manual covers SP survey design, equipment, data acquisition procedures, data reduction, and sources of SP noise. This volume marks one of a series of reports on the subject of geophysical methods and their use in assessing seepage and internal erosion in embankment dams.
