the mouth of ganges river can be found within what country
Ganges The name Ganges is used for the river between the confluence of the Bhagirathi and Alaknanda rivers, in the Himalayas, and the India-Bangladesh border, near the Farakka Barrage and the first bifurcation of the river. The length of the Ganges is frequently said to be slightly over 2,500 km (1,600 mi) long, about 2,505 km (1,557 mi),[26] to 2,525 km (1,569 mi),[27][14] or perhaps 2,550 km (1,580 mi).[28] In these cases the river's source is usually assumed to be the source of the Bhagirathi River, Gangotri Glacier at Gomukh, and its mouth being the mouth of the Meghna River on the Bay of Bengal.[27][14][26][28] Sometimes the source of the Ganges is considered to be at Haridwar, where its Himalayan headwater streams debouch onto the Gangetic Plain.[29]
Ganges Delta The Ganges-Brahmaputra Delta (also known as the Brahmaputra Delta,[1] the Sunderbans Delta or the Bengal Delta[2]) is a river delta in the Bengal region of the South Asia, consisting of Bangladesh and the Indian state of West Bengal. It is the world's largest delta and empties into the Bay of Bengal. It is also one of the most fertile regions in the world, thus earning the nickname The Green Delta. The delta stretches from the Hooghly River on the west to the Meghna River on the east.
