Figure 7. Bar area inundation compared with discharge, Chetco River, Oregon. Area inundated for each discharge was calculated on the basis of six modeled discharges between 2.8 and 17 cubic meters per second and overlaying corresponding inundated areas onto mapped bar areas. This relation was used to normalize bar and channel measurements from photograph sets to a common discharge of 2.8 cubic meters per second. Also shown are discharges for the seven photograph sets and the light detection and ranging (LIDAR) topography.
