BRAHMAPUTRA RIVER in Indian Mythology.

This river is often called Tsangpo-Brahmaputra river. The lower reaches are sacred to Hindus. While most rivers on the Indian subcontinent have female names, this river has a rare male name.

The Brahmaputra River originates in southwestern Tibet, near the source of the Indus, and is about 1,800 miles long. It passes through the Indian states of Arunachal Pradesh and Assam and serves as an important inland waterway. Although it is technically the second-largest river system that goes through India, only a portion runs within India's borders, with about 450 miles flowing through Assam's valley.

With its origin in the Angsi glacier, located on the northern side of the Himalayas in Burang County of Tibet as the Yarlung Tsangpo River, it flows across southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh (India). It flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna(not to be mistaken with Yamuna of India). In the vast Ganges Delta, it merges with the Padma, the popular name of the river Ganges in Bangladesh, and finally the Meghna and from here it is known as Meghna before emptying into the Bay of Bengal.

About  3,848 km (2,391 mi) long, the Brahmaputra is an important river for irrigation and transportation.  The lives of many millions of Indian and Bangladeshi citizens are reliant on the Brahmaputra river. Its delta is home to 130 million people and 600 000 people live on the riverside islands. These people rely on the annual 'normal' flood to bring moisture and fresh sediments to the floodplain soils, hence providing the necessities for agricultural and marine farming. In fact, two of the three seasonal rice varieties (aus and aman) cannot survive without the floodwater. Furthermore, the fish caught both on the floodplain during flood season and from the many floodplain ponds are the main sources of protein for many rural populations.
