The influence of urbanization on the morphology of the Barak River floodplain in Cachar District, Assam

Abstract In the present study, meandering behavior of Barak River (Cachar), Assam was traced. Flow path length, meander neck sinuosity index, and river migration were determined segment-by-segment to demonstrate morphological changes. Decadal land-use land cover (LULC) maps also prepared at section scale using Landsat data (1990–2020) validated with Kappa coefficient characterize changes along alluvial floodplains. Urban growth agricultural activities affect morphology, especially where intensive agriculture recorded, according LULC studies. Due urbanization, forestation constantly decreased, causing variability. According results is very slow between Sec 1 3. terms stability, parts are more stable, particularly 1, which features less urbanization activity than other sections. The most vulnerable segments within study area considered be 2 4. There a rather large amount sections, CC GG. became as new oxbow lake formed changed over decade. This stretch characterized by broad floodplain shifting since this applies various types.
