7.3 Comments Used SGAT-generated channel width to calculate Phase 1 valley confinement type. However, phase 2 channel width was consistently much greater than SGAT generated channel width for 3 assessed segments (24ft, 13ft, 15ft). Differences between the Vermont hydraulic geometry curve width of 11.5 feet and the typical Phase 2 channel width may be due to precipitation or the small drainage area. The West Branch watershed appears to receive more precipitation than other areas of the state. Another factor may be that VT hydraulic geometry curve may not be applicable to small drainages (0.75 sq. miles) such as Inn Brook. Although reference channel width is uncertain, phase 1 confinement would likely be Very Broad in any case.
