The river island of Majuli is a part of the vast dynamic river system of Brahmaputra basin with a total length of 2,706 km and a catchment area of 580,000 sq km. The fluvial landform (a riverine delta) of Majuli Island is a unique geographical occurrence as a result of the dynamics of the vast river system. The island extends for a length of about 80 km, 10-15 km north-south direction with a total area of about 875 sq km and at an elevation of 85-90 m above the mean sea level. It is formed in a stretch of the river where the largest number of tributaries drains out to form their delta on the northern and the southern banks.The north and south banks of the river Brahmaputra have wetlands- a characteristic feature of the hydrology of the system. They are locally known as Beels and are the breeding grounds of rich flora and fauna unique to this region. All of the above - the river, its tributaries, the wetlands and the chaporis along with the island of Majuli make it the largest mid river delta system in the world. The island today is separated from the mainland Assam by 2.5 km can be approached from Nimati Ghat in Jorhat district to the south of the island by ferry reaching Kamalabari in Majuli. The other mainland towns in proximity to the island on the north bank are north Lakhimpur and Dhakuwakhana. The island of Majuli today houses a total of 243 small and large villages. Of these 210 are cadastral villages (revenues generated by the administration and supported with revenue maps) and 33 are non-cadastral villages (villages without revenue maps are mostly resettled or rehabilitated shifted due to flood and erosion in Majuli).
