Figure 35. Areas of bed-material deposition and erosion volumes for selected periods in the Chetco River, Oregon. Individual reach measurements not adjusted for difference in flow stage. For each period, the total net change for the study reach was adjusted for flow differences between photograph sets (fig. 7) to determine “flow-adjusted net change” to use in calculating net bed-material influx to the study reach.
