Dendrochronological surveys on ten point-bar complexes on the Beatton River, northeast British Columbia, provide the basis for measurement of lateral migration and incision during the last 250 yr. The rate of channel-bend migration reaches a maximum value where the ratio radius of channel curvature to stream width (rm/wm) approximates 3.0. The rate of channel migration rapidly declines for bends with values of rm/wm greater or less than 3.0. In addition, the spacing of flood-plain ridges (d) increases with increasing rates of bend migration.
