About West Bengal Rivers

The state of West Bengal, a land of many rivers, covers an area of about 88,752 km2 and is the home of more than 90 million populations as per census of 2011. The Ganga divides the state into two unequal hubs: the North and South Bengal. The state has been divided into 20 districts, the seven districts are within North Bengal and remaining 13 districts are in South Bengal. West Bengal is the only state of India that extends from the Himalaya in the north to Bay of Bengal in south. It offers wide topographic diversity and intricate drainage network of 29 basins. The south Bengal can further be subdivided into two geographical units taking Bhagirathi-Hugli river (the western distributary of the Ganga) as the demarcating line. The western part is called Rarh Bengal and the eastern part is described deltaic Bengal. The rivers of West Bengal have been divided into five groups: i) the rivers of North Bengal; ii) the Ganga-Padma system; iii) the Bhagirathi- Jalangi-Churni system; iv) the western tributaries to Bhagirathi and v) the tidal creeks of Sundarban.
