Monitoring of leakage in embankment dams through resistivity measurements – A 2.5D modelling study

The study aims at improving current long term monitoring routines at two embankment dams in the north of Sweden and increase the understanding when interpreting existing data from these dams. For this purpose special software was developed as a tool for modelling resistivity distribution in earth embankment dams. The study comprises evaluation of the influence from 3D effects due to the specific dam geometry. Moreover a comparison between four different electrode arrays is carried out.
