Aerial photographs were used to characterize the geomorphic structure of the river in 1927, 1956 and 2003. The image from 1927 represents a reference range associated with the complex physical reality of the river. The results show a large reduction in bank sinuosity, a progressive loss of fluvial territory, and a large decrease in channel width. This intense geomorphological transformation becomes ecologically visible in a reduction of the area occupied by riparian vegetation; a loss of heterogeneity of riparian forest spots; and a modification of the riparian forest, which is currently linear, uniform, thin and very close to the river axis. The ecomorphological alteration was intensified by the remarkable reduction in bank length and the reduced dynamism of the present river system, indicated by an increase in the percentage of fluvial territory occupied by riparian forests and a reduction in the area occupied by the active channel
