7.5 Channel Adjustment Processes Narrative  
  Major planform adjustments, widening and aggradation following historic incision; planform adjustments heightened in response to Irene impacts - mass failures and erosion common. Multiple terrace heights indicate successive historic incision, much of it long-standing and possibly glacial, with some naturally narrow parts of valley. High terraces function as a semi-confined valley, and additional consideration of slope close to 2 pct led to question of possible plane bed reference (but ended up using unconfined evaluation due to historic incision leading to the confinement); sediment deposits not regularly setting up as either steps or riffles.
