Past, present and future of a meandering river in the Bolivian Amazon basin

Field observations on small rivers of the Amazon basin are less common due to their remote location and difficult accessibility. Here we show, through sensing analysis field works, planform evolution riverbed topography a river located in upper foreland basin, Ichilo River. By tracking changes over 30 years, identified factors that control meander migration rates River: cutoffs, climate human interventions. The data suggest neck cutoffs main controls River, with an annual density 0.022 cutoffs/km. In addition, have been form high-precipitation events may promoted increase rate channel widening. width distribution River is well represented by general extreme value inverse Gaussian distributions. spatiotemporal variability meandering analysed two locations where expected. Analysing distance across these points, predict occurrence new cutoff. combined methodology bathymetric surveys structure from motion photogrammetry shows us banks at high resolution, scour holes were identified. Finally, discuss impact communities established along its riverbanks.
