Swat river is main river of Valley of Swat. It lies in northern Pakistan, formed by the junction of the Gabrial and Ushu rivers at Kalam in the swat region.
It is fed by melting snow and glaciers and receiving the drainage of the entire Swat River valley, the river flows southward, then westward, until joined by the Panjkora River.
The united stream then flows southwestward into the Peshawar Plain and joins the Kābul River at Nisatta after a 200-mile (320-kilometre) course. The Swat canals irrigate about 160,000 acres (65,000 hectares) in which sugarcane and wheat are the chief crops.
