7.5 Channel Adjustment Processes Narrative  
  Major widening, planform change and aggradation following historic incision. Possible alluvial fan under reference conditions (though not indicated as such on soil maps, and substrate is coarse); largest deposits now accruing very close to mainstem and channel is functioning in vastly reduced floodplain. Trees critical to stability and only one row deep on RB.
