Abstract
The Gediz River basin area, and more specifically the Demir-kopru dam site, located 80 miles east of Izmir, Turkey, provides a rare opportunity to study the occurrence of five major geologic features in close proximity. Within a 2-square-mile area are major terraces, the Gediz graben, a Precambrian massif, recent volcanic rocks, and recent lacustrine deposits. The association of these features with a major engineering structure provides the basis for this paper. In early studies of the Gediz River basin, considerations were given to dam-site locations downstream of the project constructed. The alignment finally selected was at the basalt-lacustrine clay contact and takes advantage of this relationship. A 4,700,000 cubic meter earth-fill dam was constructed at the selected site.
