The unstable river flow is made evident by the meander change position. Different changes are registered by confronting multitemporal aerial photographs and satellite images. The modification quantly was measured from georeferenced images, considering some meander geometry morphometric features, in order to estimate the down stream displacement trought the last 50 years retrospective analysis.
