A large river in Western Asia. It originates near the Kurdistan mountain range in eastern Turkey, flows west, turns south into Syria, then turns southeast through Iraq, merges with the Tigris, becomes the Shatt al-Arab, and empties into the Persian Gulf. Its total length is about 2,800 km, and its drainage area is about 579,300 km2 . The water volume is lowest in September and highest in May. The lower reaches, together with the Tigris basin, are called Mesopotamia, and are known as the birthplace of the world's oldest civilization. Since the Mesopotamian plain has almost no slope, the river course has changed many times since ancient times due to floods. Currently, water resource development plans are being implemented in Turkey, Syria, and Iraq. Source : Heibonsha Encyclopedia About MyPedia Information |
西アジアの大河。トルコ東部のクルディスターン山岳部近くに源を発して西流,南に転じてシリアに入り,さらに南東に転じてイラクを貫流,ティグリス川と合流してシャット・アルアラブ川となりペルシア湾に注ぐ。全長約2800km。流域面積約57万9300km2。水量は9月が最低で5月が最高に達する。下流域はティグリス川流域とともにメソポタミアと呼ばれ,世界最古の文明の発祥の地として知られる。メソポタミア平原に入って傾斜がほとんどないため,洪水により古代から幾度も河道が変わっている。現在トルコ,シリア,イラク3国で水資源開発計画が進められている。
