Abstract

Meandering rivers dynamics has intrigued scientists since the nineteen fifties (Hooke, 2013). Meander migration models are regularly used to predict planimetric changes (Crosato, 2018), but they have not considered the figure, the reconstructed historical channel is shown. This alignment was obtained from the analysis of the existent water marks and channel trajectories that can be identified in satellite imagery. reconstruction of their historical alignments. This study deals with the reconstruction of a 9 km long reach of the Bodoquero River (see Figure 1), located in the Caquetá department, Colombia, combining the potential of meander migration models and vegetation succession to validate the modeled historical alignments.
