Abstract: Meandering rivers exhibit pronounced bends that migrate laterally and have large amplitudes, resulting in a high meander ratio. The bends of meandering rivers undergo processes of development or abandonment as they migrate due to bank erosion. Meandering is influenced by factors such as channel slope, channel width-to-depth ratio, bank stability, and sediment supply. Floodplain vegetation plays a crucial role in increasing bank stability and maintaining a low ratio of bankfull width to depth. There is a need for studies that empirically validate the behavior of meandering bends, considering both floodplain vegetation and the forcing effect of bank erosion acting on bends. This study aims to analyze the stability of riverbanks due to floodplain vegetation, the behavior of meanders in reservoirs, changes in bend curvature, and the migration of meanders by promoting the growth of alfalfa, a real floodplain vegetation, in large-scale flumes and quantitatively interpret the development of meandering and landscape changes.
