For the proposed conditions,the new ch el geometry replaced the existing channel. Cross section 1300.04 i <br /> model is the same as section 1657.04 in a proposed conditions model. The sections upstream from this locat <br /> existing conditions model. The downstr am boundary conditions remained the same as the existing condition: <br /> 1.5-yr flow in Harbison Creek was repla ed with an observed bankfull discharge for design purposes. <br /> All simulations were run with mixed flo conditions. Maiming's roughness coefficients were estimated using <br /> Arcement and Schneider(1989). <br /> Table 1.Existing conditions model plans. <br /> Plan Title Downstream Geometry Title Flow F <br /> boundary condition <br /> TokenLo Blase flow water Existing PeakQ_TokenLo <br /> siirface in Token Creek <br /> TokenlOyr l0yr flood water Existing PeakQ_Tokenl0yr <br /> surface in Token Creek <br /> Token50yr SOyr flood water Existing PeakQ_Token50yr <br /> surface in Token Creek <br /> Token100yr 100yr flood water Existing PeakQ_Token100yr <br /> surface in Token Creek <br /> Table 2.Proposed conditions model plans. <br /> Plan Title Downstream Geometry Title Flow F <br /> boundary condition <br /> TokenLo Base flow water Proposed Pro Peak TokenLo <br /> surface in Token Creek p Q— <br />
