Fig. 6From: Heuristic assessment of bridge scour sensitivity using differential evolution: case study for linking floodplain encroachment and bridge scourThe scour gradient, measured in meters of scour reduction per meter of encroachment removal, is shown for both the left and right overbanks for each of the eight cross sections. The most upstream cross section (XS\(_{1}\)) is at the far left and the most downstream (XS\(_{8}\)) at the far right Back to article page
