7.5 Channel Adjustment Processes Narrative  
  Major planform change following primarily historic incision; rate of aggradation and widening moderated by decent buffers and sediment transport discontinuity at Gulf Rd dam (US in M09). Strongly suspect ford or bridge at M09 reach break is now gone (see 1998 aerials), affecting US end of M08; Braley Bridge affects DS end. Good buffers limit rate of widening, but tipped trees tend to take large sections of bank and are primary drivers of planform change.
