a river in northwestern Turkey. The Sakarya is 790 km long and drains an area of approximately 65,000 sq km. It flows across the Anatolian Plateau, cutting through the western end of the Pontic Mountains and emptying into the Black Sea. High water is in the winter. The Sariyar Hydroelectric Power Plant (the hydraulic power engineering complex includes a dam 90 m high and a reservoir 80 sq km in area; 360 million kW-hr of electrical energy are generated per year) and the Gökçekaya Hydroelectric Power Plant are on the river. The Sakarya is used for irrigation, primarily the lower course. It is unnavigable. On the lower course is the city of Adapazari. During the Turkish War of Independence (1919–22), the decisive battle between Turkish and Greek troops took place on the river’s banks from Aug. 23 to Sept. 13, 1921, concluding with a major victory for the Turkish troops under the command of Mustafa Kemal (Atatürk).
