Flow transitions in bridge backwater analysis
WebMay 1, 1998 · Recent studies have shown that the energy method (one of the four bridge subroutines within the HEC-RAS program (HEC, 2002)) is capable of producing accurate estimates of afflux through bridge... WebFigure 4. Conceptual Illustration of Transition Reaches The flow transitions through a bridge crossing, that blocks a portion of the overbank area, is typically modeled with four cross sections. The downstream and upstream sections 1 and 4 represent the full floodplain conveyance. The bridge-bounding cross sections 2 and 3 represent
