Prepare a short note on the ‘Sunderban Delta’.
The Sunderban Delta is the world’s largest and the fastest growing delta. Filled by various tributaries, the river Ganga reaches West Bengal. This is the northernmost part of the Ganga Delta. From here, the Bhagirathi-Hooghly (a distributary) flows southwards towards the deltaic plains and the Bay of Bengal. The main stream flows southwards into Bangladesh and is joined by Brahmaputra, known as Meghna. This mighty river (with waters from Ganga and Brahmaputra) forms the deltaic plains and then flows into the Bay of Bengal. It derives its name from the Sundari tree which grows in marshland.
