Abstract: This paper presents the results of a clear-water scour experiment where the sediment kinematics around a rectangular abutment was measured at various evolution stages of the erosion process. Sediment activity was quantified ...

Abstract: The flow field around a bridge abutment is analyzed by means of large eddy simulation. The geometrical configuration corresponds to the initial condition of a scour process (flat bed). The three-dimensional flow structure ...

Abstract: The erosion process at a bridge abutment may be affected by the flow constriction when the abutment occupies a significant part of the flume width. We devised a specific experimental campaign to investigate the effect of ...

Abstract: Live-bed scour at a vertical-wall abutment is experimentally investigated with specific attention paid to the conceptual issues concerning the temporal development of local scour phenomenon. First explored are the time ...

Abstract: The effect of the intense transport of lightweight sediment without turbulent suspension (Shields numbers of mixture flow from 0.34 to 1.80) on resistance and surface elevation of water flow in an open channel is experimentally ...

Abstract: This paper reports the double-averaged (in space and in time) hydrodynamic equations for mobile-boundary conditions that are derived based on the refined double-averaging theorems, modified Reynolds decomposition, and ...

Abstract: In this paper, we propose a new predictor for the time-dependent, spatially-maximum scour depth at a circular pier in clear-water flow conditions. In spite of a number of approaches used in scour research, a simple predictor ...
