A shoal becomes a bar and gradually increases in length, width and height under these two favourable conditions and growth of vegetation makes it a permanent one. The River Gumti, the largest river of Tripura with a catchment area of 2492 km2, is facing the problem of siltation in its plain stretch. The total discharge of the river is 3738 m3/s and total annual flow is 24, 93, 99,000 m3. The total amount of sediment load was increased about 3.7 times between 2008 and 2010 whereas discharge becomes half between 2007 and 2010. | | Keywords : | | |
