7.5 Channel Adjustment Processes Narrative  
  Major aggradation and loss of planform due to damming and bank armoring. Widening limited by extensive rip-rapping, with w/d ratio in E stream-type range. Low sinuosity however, and significant aggadation of fines. Suspect this would be a reference C stream and have thus given 'Other' stream type departure, C-->E, for aggradation and planform.
