Lake Tharthar (also Therthar), and known in Iraq as Buhayrat ath-Tharthar ((アラビア語:بحيرة الثرثار)), is an artificial lake opened in 1956, situated 120 kilometers north of Baghdad between the Tigris and the Euphrates rivers. ==Description== Tharthar covers roughly , flows from the central and eastern parts of Sinjar Mountains and adjacent hills, with a floor of – 3 m, above the sea level. The maximum length and width of the depression are 120 and 48 Km, respectively. The eastern rim of the depression is higher than the western one, the heights of both rims are and , respectively. The Tharthar depression formed During Holocene age, mainly by karstification, due to dissolving of gypsum rocks of the Fatha (nearby area) Formation.〔 In 1956, the southern part of the Tharthar depression was turned into an artificial reservoir to collect flood waters of the Tigris River. The water flows via an artificial inlet canal,named Tharthar Canal. The canal diverts the access water, by means of a regulator Samarra Barrage. It merges with the lake in its southeastern bank. The lake has an artificial outlet called Taksim Tharthar Canal, which drains to the Euphrates River directly. The canal, after 28 km from its outlet, bifurcates to another canal called "Dhira'a Dijla" (arm of tigris) that returns water back to the Tigris River. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Tharthar」の詳細全文を読む スポンサード リンク
