Temporal relations between meander deformation, water discharge and sediment fluxes in the floodplain of the Rio Beni (Bolivian Amazonia)

Abstract

Channel migration, meander-bend morphology and ox-bow lakes are analysed at different temporal and spatial scales in the floodplain of the Rio Beni. The AA. first investigate the conditions of sediment exportation in the river in relation to 3 hydrological parameters (flood intensity, date of discharge peak and duration of the bank-full stage level). Then, they focuse on the abandoned meanders, analyse the cutoff processes and the post-abandonment evolution during 1967-2001. This approach shows the influence of the active channel behaviour on the sediment diffusion and sequestration of the abandoned meanders and allows to build a model of the contemporary floodplain evolution
