Sundarbans delta is formed by the Ganga and Brahmaputra rivers.
The Ganges-Brahmaputra Delta (also known as the Brahmaputra Delta, the Sundarbans Delta or the Bengal Delta) is a river delta in the Bengal region of the Indian subcontinent. The name Sundarbans is thought to be derived from sundri or Sundari (Heritiera fomes), the name of the large mangrove trees that are most plentiful in the area.
