Explanation: The Indus System is one of the largest river basins of the world. It is also known as  the Sindhu, is the westernmost of the Himalayan rivers in India. It originates from a glacier near Bokhar Chu (31°15' N latitude and 81°40' E longitude) in the Tibetan region at an altitude of 4,164  m in the Kailash Mountain range. It receives a number of Himalayan tributaries such as the Shyok,  the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, the Gasting and the Dras. The Indus System  is one of the largest river basins of the world, covering an area of 11, 65,000 sq. km (in India it is  321, 289 sq. km and a total length of 2,880 km (in India 1,114 km). The Indus also known as the  Sindhu. It originates from a glacier near Bokhar Chu (31°15' N latitude and 81°40' E longitude) in  the Tibetan region at an altitude of 4,164 m in the Kailash Mountain range. In Tibet, it is known  as ‘Singi Khamban; or Lion’s mouth. After flowing in the northwest direction between the Ladakh  and Zaskar ranges, it passes through Ladakh and Baltistan. It cuts across the Ladakh range, forming  a spectacular gorge near Gilgit in Jammu and Kashmir. It enters into Pakistan near Chillar in the  Dardistan region.
Tributaries of Indus River: The Indus receives a number of Himalayan tributaries such as  the Shyok, the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, the Gasting and the Dras. It  finally emerges out of the hills near Attock where it receives the Kabul River on its right bank. The  other important tributaries joining the right bank of the Indus are the Khurram, the Tochi, the Gomal,  the Viboa and the Sangar. They all originate in the Sulaiman ranges. The river flows southward and  receives ‘Panjnad’ a little above Mithankot. The Panjnad is the name given to the five rivers of  Punjab, namely the Satluj, the Beas, the Ravi, the Chenab and the Jhelum. It finally discharges into  the Arabian Sea, east of Karachi.
