A meandering river undergoes erosional and depositional phases. The erosional phase if characterized by continuous cutoffs and the depositional phase is characterized by the increase on planform migration rates. By these two processes, the Ucayali River preserves its dynamic equilibrium condition. This study presents a methodology that combines analysis of satellite images, high-resolution measurements of bed morphology and water velocities, as well as hydrodynamic modeling of the study reach. This study serves as foundation for developing morphodynamic predictive models for not only bed morphodynamics, but also planform morphodynamics. © 2012 Taylor & Francis Group, London.
