Comments:
Braided section in this segment but dominant bed form is riffle-pool. Recent tree cutting (observed 5/3/12) on banks and in riparian corridor on both sides on downstream end of segment. Right bank corridor is shared with Tributary 10 and shrubs and trees have been cut down. It is recommened to determine the meander width ratio and the wavelength ratio to help assess the stability of the reach. This was not done as part of Phase 1. 2015 ASSESSMENT NOTES: In 2015, when the Phase 2 assessment was repeated on R48-B, the geomorphic features observed were very similar to those noted in 2011. Most notable of the changes that occurred between 2011 and 2015 include the formation of a mass failure along the left valley wall at the upstream end of the segment. Also, a headcut was observed in a different location in 2015 than the one observed in 2011. In 2015, a headcut was observed downstream of where one was observed in 2011. The geomorphic and habitat condition of R48-B were the same in 2015 as 2011 – fair and good, respectively.
