The Keban dam foundation on karstified limestone—A case history

Bozovic, A. / Budanur, H. / Nonveiller, E. / Pavlin, B.

Abstract The Keban dam on the Firat was erected on a limestone ridge deeply karstified mainly by hydrothermal activity. Extensive highly interconnected percolation paths resulted in and below the dam foundation which convey inpounded water below the 250 m deep grouted cut-off into Keban Creek and to sources downstream of the dam. The cut-off, the cavern discovered after filling the lake and its treatment, the leakages before and after remedial measures were achieved, are presented.
