Abstract
A study of the relationships between archaeological sites and the previous channels of the Ucayali River in eastern Peru supports the archaeological chronology already established on stratigraphic grounds. These relationships also suggest that the average duration of a meander loop from inception to cut-off is about 500 years. This 500-year cycle offers an explanation for, and a measure of, the temporal lacunae separating the various components of multicomponent sites on the bluffs adjoining the Ucayali flood plain. The extent and rapidity of geomorphological evolution in this region must be considered when one attempts to evaluate the data of site density and site location, since many archaeological sites are quickly destroyed or buried.Keywords
