7.5 Channel Adjustment Processes Narrative  
  This segment widened during T.S. Irene followed by major aggradation and planform adjustment. Large volumes of sediment working through the segment contribute to ongoing meander development. Numerous recent and active flood chutes and an avulsion were observed. We assessed this reach as Stage IV.
