Abstract
Akkopru Dam, which is under construction, is located at Dalaman Basin in the southwest of Turkey. The base rock at the Akkopru dam site and reservoir area is autochthon Aktas limestone and Gokseki flysch formation. Allochthon Cehennem Deresi limestone, a complex series of ferro- (melange) and peridotite–serpentine units, overlay this unit with tectonic contact. These units are covered by young sedimentary series. The outcrops of karstified Aktas limestone are observed at 2 km upstream of the dam site, at the right reservoir abutment. This unit is very permeable and the groundwater level is very deep, 100–116 m below the Dalaman riverbed. After impoundment, 250,000 m2 of this unit will be submerged. Groundwater which percolates in this unit discharges at the coastal springs. This study analyzed the watertightness of Akkopru reservoir related to the karstified limestone in the left reservoir bank and discussed possible options of remedial works to reduce seepage.
