Scour at bridge sites is the removal of bed material from around piers, abutments, and embankments. One of the components of total scour is local scour at bridge piers, which is caused by the acceleration of flow and by vortices resulting from flow around an obstruction, in this case, a pier. The described phenomenon can potentially disrupt the stability of the bridge and its traffic safety. The aim of this paper is to determine the extent of scour at bridge piers of different geometry under different hydraulic conditions (flow velocity, flow depth and flow) on a scale model in a hydraulic channel. Tests were conducted on 4 scale model piers of different shapes in a hydraulic channel, which was 2 m in length and 0.8 m in width. Following the tests, the conducted data were analyzed. It was determined that the largest scour depth was on a pier of square cross-section, and the smallest was on a pier of circular cross- section. In the case of the pier with a complex shape, no scour occurred, or it was negligibly small. Tests confirmed that the most suitable pier is the one that is shaped in such a way that the shape of the upstream part reduces its flow resistance.
