The Indus River is a 3,180-kilometre (1,980 mi) transboundary and trans-Himalayan river that rises in western Tibet before flowing northwest through the regions of Ladakh and Gilgit-Baltistan in Kashmir. The river then bends sharply to the left after the Nanga Parbat massif, flows generally southwest through Pakistan, and empties into the Arabian Sea near the port city of Karachi. The Indus has a total drainage-basin area exceeding 1,165,000 km2 (450,000 sq mi). Its estimated annual flow is around 243 km3 (58 cu mi), making it one of the fifty largest rivers in the world by discharge.
