7.5 Channel Adjustment Processes Narrative  
  Historic incision has left multiple terraces. Irene caused major widening, aggradation and planform changes. Post storm alterations (snagging, dredging and new riprap) confuses/exacerbates stream processes as the stream adjusts to Irene impacts. Segment overall tends towards B-valley. Channel alteration reduces level of confidence in assessment as Planebed reference bedform, but slope (2.7%) and confinement (Narrow) are a fit for a disorganized reference planebed where neither steps or riffles set up regularly
