Indus, a great river of India, 1800 m. long; rises in Thibet, on the N. of the Himalayas, flows NW. through Cashmere, then SW. through the Punjab and Sind to the sea; its upper course is through great gorges and very rapid, but after the entrance of the Kabul River its way lies through arid plains, and it is navigable; after receiving the Panjnad its volume decreases through evaporation and the sinking of some of the many streams into which it divides in the sand; on one of the branches of the delta stands the thriving port of Kurrachee.
