Mouths of the Indus River, Pakistan
The Indus River is a trans-Himalayan river of southern Asia. It is one of the world’s longest rivers, with a length of 1,800 mi (2,900 km). Its annual average flow of 207 billion cubic meters is twice that of the Nile.
Here, its mouths are visible along the coast of Pakistan, below the city of Karachi. It rises in southwestern Tibet and flows northwest through valleys of the Himalayas. After crossing into the Kashmir region, it continues northwestward through the Indian- and Pakistani-administered areas and then turns south into Pakistan.
Swelled by tributaries from the Punjab region, including the Jhelum, Chenab, Ravi, Beas, and Sutlej rivers, it widens and flows more slowly. It has supplied water for irrigation on the plains of the Indus Valley since early times.
