Comments:
Heavy road encroachments on left bank, extensive rip rap. Possible plane-bed reference (Narrow/Semi-confined valley, 2.8 pct slope by GIS calc); numerous steep riffles and steps due to location at downstream end of overall stream, with significant aggradation and large mobile particles. Alluvial fan noted in seg is at US end of reach, just below confluence with trib: very coarse particles but significant aggradation. Soil maps indicate alluvium further US, but series of recent flood events has dumped a lot of sediment at head of this reach. Valley is borderline Narrow/Semi-confined, functionally Semi-confined in many areas due to road encroachment but intermittently able to access the wider valley in major floods.
