Himalayan Rivers
• Indus, Ganga and Brahmaputra comprise the Himalayan river systems.
• The Himalayan Rivers existed even before the formation of Himalayas i.e.  
before the collision of Indian Plate with the Eurasian plate. {Antecedent  
Drainage}They were flowing into the Tethys Sea.
• These rivers had their source in the now Tibetan region.
• The deep gorges of the Indus, the Satluj, the Brahmaputra etc. clearly  
indicate that these rivers are older than the Himalayas.
• They continued to flow throughout the building phase of the Himalayas;  
their banks rising steeply while the beds went lower and lower due to 
vertical erosion thus cutting deep gorges.
• Thus, many of the Himalayan Rivers are typical examples of antecedent  
drainage.

Indus
river
• Indus River (locally called Sindhu) is  
one of the longest rivers in Asia.  
Originating in the Tibetan Plateau in  
the vicinity of Lake Manasarovar
• India got her name from Indus.
• „The Indus Valley Civilization? was  
born around this river.
• It ? slength is about 2,900 km. Its total 
drainage area is about 1,165,000  
square km [more than half of it lies in  
semiarid plains of Pakistan].
• It is joined by Dhar River near Indo-
China border.
