Majuli Mājuli or Majoli (pron: ˈmʌʤʊlɪ) (Assamese: মাজুলী, Assamese pronunciation: [mazuli])[1] is a river island in the Brahmaputra River, Assam, India and the 1st island district of the country.[2] The island had a total area of 1,250 square kilometres (483 sq mi) at the beginning of the 20th century,[3] but having lost significantly to erosion it had an area of only 352 square kilometres (136 sq mi) in 2014.[4] Majuli has shrunk as the river surrounding it has grown.[5] However it is recognised by Guinness Book of World Records as World's Largest River Island.[6]
Yamuna The Yamuna (Hindustani: /jəmʊnaː/), also known as the Jumna, (not to be mistaken with the Jamuna of Bangladesh) is the longest and the second largest tributary river of the Ganges (Ganga) in northern India. Originating from the Yamunotri Glacier at a height of 6,387 metres on the south western slopes of Banderpooch peaks in the uppermost region of the Lower Himalaya in Uttarakhand, it travels a total length of 1,376 kilometres (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganges Basin, before merging with the Ganges at Triveni Sangam, Allahabad, the site for the Kumbha Mela every twelve years. It is the longest river in India which does not directly flow to the sea.
