“…In the study area, floodplain restoration for floodwater, sediment, or nutrient storage would likely be most effective downstream of reach M17 (greater than approximately 90 km 2 of drainage area). - Reaches (i.e., M05, M19A, M19B, and M20; see Supplemental S.9) with SSP‐flow curves that exceed critical SSP Thresholds at small design floods such as the Q5 (e.g., Figure 6, Note 1), may be good choices for restoration projects either at the reach itself or in upstream reaches to attenuate peak flows and dissipate flood energy and erosion/incision hazard (Gourevitch et al, 2020; Morris et al, 2005; Rijke et al, 2012).
- Reaches (i.e., M06, M08, M11, M13, and M15) that have large DSVC accessed at small design floods or have CSVC accessed only at moderate design floods (Figure 6, Note 2) may be good choices for channel reconnection (e.g., berm lowering or removal; installation of cross‐culverts beneath roads) (Morris et al, 2005; Worley et al, 2022).
- Reaches with large CSVC that can be accessed at small design floods (i.e., M05, M08, M10, M11, M12, and M16) may be most suitable for conservation easements.
