THROUGH THE DAMS
Internal erosion is one of the major reasons for embankment dam failures.
Monitoring of electrical resistivity may have possibility of detecting
internal erosion processes and anomalous leakage at an early stage before
the safety of the dam is at stake.
TEM-FAST technique is essentially non-destructive, which is very important
when working with embankment dams where drilling and other penetrating
investigations are normally avoided. The example presents results of a
TEM-FAST investigation of the dike carried out at the Spakenburg in the
Netherlands (summer 2004).
Another example of the section along the
profile crossing the dike located just near Kijkduinpark - The Hague
(autumn 2004) is shown below
