Non-destructive survey of the "dam crest - serpentine on the downstream slope" route and the downstream area of the Gotsatlinskaya HPP dam in order to identify signs of flooded areas.
Results
Filtration zones are traced from the dam base embankment to the right bank of the canal, and are probably controlled by an erosion incision.
The unloading of underground seepage waters occurs in a section ~140 m long.
To clarify the source of seepage water, further inspection is needed in the lower part of the embankment slope.
Value
Non-destructive operational determination of filtration zones of soil dams.
