Gediz River
river in Erzurum, western Turkey
The Gediz River (Turkish: Gediz Nehri, Turkish pronunciation: [ˈɡediz]) is the second-longest river in Anatolia flowing into the Aegean Sea. From its source of Mount Murat in Kütahya Province, it flows generally west for 401 km (249 mi) to the Gediz River Delta in the Gulf of İzmir.
Name
The ancient Greek name of the river was Hermos (Ἕρμος), Latinized as Hermus.
The name of the river Gediz may be related to the Lydian proper name Cadys; Gediz is also the name of a town near the river's sources. The name "Gediz" may also be encountered as a male given name in Turkey.
Ancient geography
The Gediz is one of the two candidates for the Hittite placename Seha River, the other being the Bakırçay.
The Hermos separated Aeolia from Ionia, except for Ionic Phocaea, which was north of the Hermos. The valley of the Hermos was the heartland of the ancient Lydian Empire and overlooking the valley was the Lydian capital Sardis.
Location
In Turkey's Aegean Region, Gediz River's length is second only to Büyük Menderes River whose flow is roughly parallel at a distance of slightly more than a hundred kilometers to the south.
Gediz River rises from Murat Mountain and Şaphane Mountain in Kütahya Province and flows through Uşak, Manisa and İzmir Provinces.
