Detailed explanation-4: -Floodplain wetlands are characteristic features along the rivers Ganga, Brahmaputra and Barak basin, especially along their middle and lower stretches in the eastern and north-eastern parts of India. Most of the tributaries of Ganga river support floodplain wetlands in Uttar Pradesh, Bihar and West Bengal.
