The Indus is one of the most important drainage systems of the subcontinent of India.
The Indus is the western most River system in the subcontinent.
Jhelum, Chenab, Ravi, Beas and Satluj are its main tributaries.
The Indus originates from the Bokhar Chu (glacier) in northern slopes of Mt. Kailash (6714m).
It drains the largest number of glaciers and mountain slopes of the Karakorum, Ladakh, Zaskarand Himalayan Ranges.
Originating from the Kailash Mountain, it flows in a constricted valley north-westward through Tibet, where it is called as Singi Khamban or Lion’s mouth.
In ladakh it follows a long nearly straight course between the Ladakh range and the Zaskar range.
In the first 480 km, it flows along the northern flank of the Zaskar range over a flat country at heights over 3200 m where it receives River Zaskar below Leh.
Suruand Dras are the other left bank tributaries which join the Indus near Kargil.
Moving north-westward, the Indus is joined by the Shyok-Nubra tributaries.
These tributaries arise from the Siachin Glacier (Karakoram Range).
At Skardu, at a little distance below the Shyok, the Shigar River meets River Indus.
Gilgit is another important tributary which comes from the west to join Indus.
Downward; the Indus crosses the central Himalayan range through a huge synclinal gorge.
The River passes by the Nanga-Parvat and turns south-west to enter Pakistan.
