7.5 Channel Adjustment Processes Narrative  
  This reach appears to have widened slightly during recent episodic flooding. Banks now appear stable for most of the reach. Channel is exhibiting lateral movement and is in stage IV. We observed slumping banks and increased scour on outside bends (due to low severity and scale these features were not indexed as erosion). A small alluvial fan at the top of the reach and increased gravel and sand deposition throughout indicate that increased bedload from recent episodic flooding events may still be working through the reach.
