Sediments from Karun River Spilling into Shatt al-Arab and Persian Gulf, Iraq30.5N 47.8E
The Shatt al-Arab, literally meaning “Coast/Beach of the Arabs”, is a river in Southwest Asia formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq. The southern end of the river constitutes the border between Iraq and Iran down to the mouth of the river as it discharges into the Persian Gulf.
The river is approximately 200 km (120 mi) in length. It varies in width from about 232 metres (761 ft) at Basra to 800 metres (2,600 ft) at its mouth. The Karun River, a tributary which joins the waterway from the Iranian side, deposits large amounts of silt into the river; this necessitates continuous dredging to keep it navigable. Here, sediments from the rivers can be seen pouring into the northern end of the Persian Gulf.
