Figure 9. Summary of channel change in the study area, Chetco River, Oregon, 1939–2008. Bar extensions in lighter shades for bar area and channel width represent values normalized to a discharge of 2.8 cubic meters per second (m³/s). The photographs from 1939 only partly cover the Upper Reach; hence, no measurements from 1939 are available for bar area and sinuosity for that reach, and channel width is only a partial measurement.
