The Brahmaputra is an important river of southern Asia. It has its source in the slopes of the northern Himalaya in western Tibet. The Brahmaputra flows eastward through Tibet, passing Lhatse Dzong and Lhasa, before it turns south, entering the eastern region of India, Assam. Then the Brahmaputra flows to the west through Bangladesh where it merges with the Ganges, forming the Ganges river delta, terminating in the Bay of Bengal.
The Brahmaputra flows for a total of 1,680 miles (2,704 kiliometers). Only the 800 miles (1,300 kilometers) from the mouth of the river in the Bay of Bengal to the Brahmaputra river valley in Assam are navigatible. From that point on, the river consists of stretches of trecherous rapids. In Tibet, the northern Brahmauputra is called by many names, the most prominent of which is Yarlung Zanbo.
The river valley in Assam is one of the most fertile in all of Asia. Ther river provides for natural irrigation, flooding the countryside in the rainy season. Rice, tea and jute are some of the most bountiful crops.
The paintings of Nicholas Roerich depict hundreds of scenes of the Brahmaputra in India and Tibet. Most of these were composed on the Roerich Central Asian Expedition of 1929.
