| dc.description | Abstract: Surface electrical geophysical surveys were used to detect and monitor seepage paths through the right (south) abutment at Gathright Dam. The merits of these geophysical surveys are documented as a case study. Spontaneous potential (SP) techniques determine the anomalies created in the ambient electrical field by water flowing through porous zones in the subsurface materials. Both static and injection-induced potential anomalies were investigated at this site. Wenner and Bristow-Bates resistivity surveys were performed in limited areas to verify SP results. The Norfolk District drilled several core borings which indicated success of the SP and resistivity tests. The results of dye and salt injection testing, as monitored by fixed SP electrode arrays, are presented in the report. | - |
