Biomorphodynamic modelling of inner bank advance in migrating meander . . . A bio-morphodynamic model for lateral migration of river meander bends is proposed Bank advance is related to the interaction between vegetation and river processes Physical controls of bar push and channel width temporal variation are investigated Insights into the topographical pattern typical of meander floodplains are provided
Flow in meander bends with recirculation at the inner bank In highly curved river bends, flow may separate at the inner bank to create a recirculation eddy with weak upstream flow Very little is known about how recirculation eddies connect with the downstre
Human interventions alter meandering channels evolution: Insights from . . . In meandering rivers, the secondary flow induced by the centrifugal force transports the sediment to the inner bank, leading to the inner bank deposition and outer bank erosion (Abad and Garcia, 2009; Lotsari et al , 2014; Konsoer et al , 2016)
A Numerical Model of Bank Collapse and River Meandering Our results show that the migration of meander bends can be described through a catch-up behavior, driven by outer bank collapse and subsequent inner bank accretion, that on average ensures a nearly constant channel width
Bed morphology in vegetated estuarine river with mild-curved meander bend Vertical distributions of the streamwise velocity at the inner bank, centreline and outer bank at the meander apex are shown in Figure 7 for comparison The vertical velocity distribution was also compared with a logarithmic law velocity distribution (denoted by LLM in Table 1)
A Numerical Model of Bank Collapse and River Meandering Meander migration results from the interaction between inner bank accretion and outer bank erosion collapse This interaction has been usually treated as a long-term average of a sequence of
Channel morphologic processes of a highly sinuous bend approaching neck . . . Geomorphologically, erosion-deposition adjustments on the inner bank and outer bank under the impacts of intense human activities usually are much more drastic than meander bends affected by the natural hydrologic regime and boundary conditions (Richards Konsoer, 2020; Rumsby Macklin, 1994; Surian Rinaldi, 2003)
Meander - Wikipedia Meanders are a result of the interaction of water flowing through a curved channel with the underlying river bed This produces helicoidal flow, in which water moves from the outer to the inner bank along the river bed, then flows back to the outer bank near the surface of the river
Flow in meander bends with recirculation at the inner bank [1] In highly curved river bends, flow may separate at the inner bank to create a recirculation eddy with weak upstream flow Very little is known about how recirculation eddies connect with the downstream flow or how the latter is affected by their presence
