7.5 Channel Adjustment Processes Narrative  
  This reach widened during the 2011 floods followed by major aggradation of flood related cobble and gravel. Planform adjustments are occurring as the river carves meanders through these sediments within the widened channel. A large channel avulsion occurred where the river dumped a huge volume of cobbles in the historic channel and is carving a new channel through the right bank with an active but small headcut.
