The model predicts water surface elevations, flow regimes, water velocity and <br /> shear stress along the modeled segment. <br /> Using results from the model, channel stability analyses were conducted to establish <br /> stable channel dimensions and rock size to accommodate the range of expected flows. <br /> Design alternatives were discussed for the upstream segment, which extends from the <br /> pipe crossing to the culvert outlet. <br /> OREGON WASHINGTON MONTANA WISCONSIN _ <br /> <br />
