Çatalan Dam is an embankment dam on the Seyhan River dam in Adana Province, Turkey. It is 22 km (14 mi) north of the city of Adana. Constructed between 1982 and 1997, the development was backed by the Turkish State Hydraulic Works. [1]
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.
The Seyhan River is the longest river in Turkey that flows into the Mediterranean Sea. The river is 560 km and flows southwest from its headwaters in the Tahtalı-Mountains in the Anti-Taurus Mountains to the Mediterranean Sea via a broad delta. Its main tributaries are Zamantı and Göksu, which unite in Aladağ, Adana to form the Seyhan River. The Zamantı River originates from the Uzun Plateau in Pınarbaşı, Kayseri and crosses Tomarza, Develi and Yahyalı districts in Kayseri.
