WebThe equilibrium scour depth is achieved when material is transported into the scour hole at the same rate at which it is transported out. Typically the maximum equilibrium clear-water scour is about 10% larger than the equilibrium live-bed scour. Conditions that favour clear water scour are: Bed material that is too coarse to be transported WebApr 7, 2024 · If the 140-foot span length (L) is the longest span of any continuous span plate girder bridge, the minimum steel plate girder depth = 0.027 x L = 0.027 x 140 x 12 = 45.36 inches, and the overall minimum … mnc farm west bridgewater ma

WebThe principal difference lies in the contraction ratios used; Gill used the full channel contraction ratio (approach channel width divided by bridge opening width), whereas Laursen used an assumed contraction width equal to the estimated scour hole width, resulting in the contraction ratio = (2.75ds+L)/2.75ds, where ds is scour depth below the ...
