The document summarizes the results of a HECRAS model of a river reach. The model used terrain data from Civil 3D, assumed Manning's n of 0.04, and modeled flows of 3.8 m3/s and 75 m3/s. The results include longitudinal profiles, velocity, flow area, width, Froude number, depth, volume, and stream power graphs along the reach for both flows. Cross sections are also shown at various locations along the reach.
