7.5 Channel Adjustment Processes Narrative  
  Arrested stage II-III, incision limited by 2 check dams just DS (in next seg) and ledge grade control in next seg US; widening limited by complete walling of banks. 'Other' stream type departure is C to E, as w/d ratio is in E range (due to extensive walling) but stream retains access to floodplain in moderate or higher level floods.Check dams and walls will require ongoing maintenance, and amplify flows until moderate or higher level floods when FP is accessed - at which point residential/commercial neighborhood floods (repeat area). Loss of planform and limited opportunity for adjustments.
