چکیده انگلیسی
Scientific surveys regarding the mechanisms of transportation of bed material grains from the scour hole are undersupplied in literature. This work takes into account the mechanisms behind a local scour, associated with a bridge pier impact. In order to gather information about the flow field, an appropriately formulated numerical model of flow was used, the so-called LES (large-eddy simulation). The numerical analyses carried out in this work, examining the mechanisms of the transportation of bed material grains by means of a suitably formulated flow model, constitute theoretical background for the analysis of velocity fields around bridge piers. Those analyses will come in handy during hydraulic computations of bridges.
