7.5 Channel Adjustment Processes Narrative  
  This segment heavily encroached upon by Smokeshire Rd. This encroachment has eliminated flood plain access and caused historic incision. During T.S. Irene this channel aggraded from flood deposits and is now widening as seen by the consistent scour along the banks throughout the reach. This scour and increase in channel width indicates that this reach is in stage III of channel evolution.
