Comments:
Reach has gone through multiple years of adjustment, likely after initial land use impacts from deforestation and conversion to pasture. Assessed in stage V of channel evolution b/c of evidence of reestablishment of new floodplain at lower elevation. Although channel geometry measurements and cross section data (low w:d ratio) suggest an E type, C type features dominate throughout reach. Future assessment work in this watershed should include additional cross section measurements to verify channel type.
