In order to solve the prediction and protection problems of local pier scour with a downstream sediment storage dam on non-uniform sand riverbeds in mountainous areas, Xi’an Chanhe Bridge China was taken as research object. Through comprehensive physical model experiments, influence layout surrounding water flow morphology around bridge piers studied. The relationship between boundary condition...

Local scour around bridge piers and abutments is one of the most significant causes failure. Despite a plethora studies on individual or abutments, few have focused joint impact pier an abutment in proximity to another scour. This study conducted laboratory experiments flow analyses examine interaction their effect clear-water The were rectangular flume. They included 18 main tests (with combin...

Current research investigating ice-covered bridge pier scour has focused on the effects of fully developed ice jams. However, based observations at various stages development, covers are not always developed. This experiment investigated a simulated floating jam’s with constant flow rate. Various channel-spanning cover lengths were tested, along one circular localized cover, and resulting was c...

Throughout the lifespan of a bridge, morphological changes in riverbed affect variable action-imposed loads on structure. This emphasizes need for accurate and reliable data that can be used model-based projections targeted identification risk associated with bridge failure induced by scour. The aim this paper is to provide an analysis scour depth estimation large sand-bed rivers under clear wa...
