The load of the rivers such as Ganga-Brahmaputra, comprising sand, silt and gravels, is tremendous. This gets deposited in the deltas or the lower course of river over a long period forming river islands. These islands can be temporary or permanent because they may also disappear when the volume of river water or its speed increases. Majuli, Assam, in the Brahmaputra is a permanent riverine island which is rich in biodiversity.
Chars in Bangladesh are mostly islands formed in large deltas of the Ganga-Brahmaputra system. Mostly these islands are not permanent as they last as long as the river is full of sediments and is slow. What do you think is the land use in chars?
