There was significant variability in erosion/deposition within each
morphological setting from week to week. Fig. 5 displays boxplots for
weekly pin change for individual channel pins, which shows a mean
change near zero, but a large range in pin change from week to week.
The pattern for the sidewall and interfluve pins is similar, with a range
of 120 mm and 50 mm, respectively. The four erosional measures
