7.5 Channel Adjustment Processes Narrative  
  The reach is encroached by Grafton Road and Popple Dungeon Road throughout and as a result has reduced floodplain. Incision is limited by numerous grade controls and we observed minimal evidence of widening. Opportunities for widening and planform adjustment are limited due to bank armoring. We assessed this reach as stage II due to the current degree of incision, however, due to grade control it is unlikely to incise further.
