Investigation of shallow leakage zones in a small embankment dam using repeated resistivity measurements in Internal erosion in embankment dams and their foundations
(2011) Internal Erosion in Embankment Dams and Their Foundation 13. p.165-172- Abstract
- Resistivity measurements were carried out in order to identify preferential seepage paths in a small dam in central Sweden. Increased seepage flow had been observed at high reservoir levels. Repeated resistivity measurements were performed along the dam crest during 24 hours controlled rising of the reservoir. Each measurement data set was compared to the original reference data set using time-lapse inversion. Zones with gradually decreasing resistivity were identified inside the dam at the depth corresponding to the changed reservoir level. The zones were interpreted as preferential seepage paths. During a possible future repair of the dam this interpretation may be evaluated.
