7.5 Channel Adjustment Processes Narrative  
  This reach is deeply incised and likely stuck there due to natural and man-made hard banks. Some aggradation was observed and moderate to heavy scour was present along most of the banks, however potential widening and planform adjustment are very limited. Further incision is unlikely due to low gradient and downstream impoundment.
