Comments:
Many planform changes as a result of aggradation and abundant debris jams. No apparent straightening due to tight valley and steep side slopes. Despite low entrenchment value and low w:d, this reach is a C-type. In lower section of reach where physical adjustments are not as severe, slope is slightly higher and plane bedform dominates (which is assumed to be reference bedform). In upper section of reach, slope is slightly less and riffle-pool bedorm is likely reference. Segmentation was not deeded necessary b/c of the overall homogeneity of the entire reach. Reference bedform conditions have been assessed as riffle-pool (which dominates reach), with impacts from aggradation causing departure to plane-bed features in much of upper reach.
