7.5 Channel Adjustment Processes Narrative  
  Major planform adjustments and widening, with major to minor aggradation, following historic incision. 15 ft wall of riprap placed on RB along base of Dickerman Rd following flood damage within last decade. Segment is on likely glacial alluvial fan, though current valley is more entrenched; used +/-2w/d 'fudge factor' to class as C-type stream due to low sinuosity for an E-type stream. Reduced sinuosity likely due in part to slope as well as entrenchment.
