7.5 Channel Adjustment Processes Narrative  
  This segment historically has been straightened and encroached by Weston-Andover Rd, thus greatly reducing its ability to widen or adjust planform. The presence of berms further exacerbate this problem, causing the widespread incision. Since the July 2014 floods no major deposition or migration features were observed, which indicates the reach continues to be stuck in stage II of channel evolution.
