The Gangotri glacier of Gomukh (an ice cave in the Himalayas) is the source flowing southward is known as Alakananda. The Ganga is formed by these two head streams when they meet at Devaprayag. Beyond Farakka in West Bengal, the mainstream of the Ganga which flows east-south-eastward into Bangladesh is known as Padma. A bifurcation channel runs southwards through the deltaic plan on to the sea. Here the river is known as the Bhagirathi-Hooghly. To the east of the Pabna (near Goalundo), the Padma receives the Brahmaputra known here as Jamuna. The combined stream continues to flow as Padma, till is receives the Meghna to the north of Chandpur. The Ganga and the Brahmaputra form the largest delta of the world, the Sunderbans. The Ganga has numerous larg and small tributaries. The Ram Ganga, the Ghaghra, the Gandhak and the Kosi are its major left bank tributaries while the Yamuna and the Son form the major right bank tributaries.
