Impact of Local Scour around a Bridge Pier on Migration of Waved-Shape Accumulation of Ice Particles under an Ice Cover

The migration of a waved-shape accumulation ice particles under an cover (referred to as “ice wave” in this study) is phenomenon transport during process rivers. wave will affect the pier scour. On other hand, local scour at waves. interaction between waves and around very complicated since not only channel bed deforms, but also jam develops simultaneously. By conducting series flume experiments, bridge piers was studied. applying both continuity momentum equations, empirical equation has been derived for predicting thickness pier. impacts hole on have crest speed investigated. Similar sand bed, hole” appeared bottom existence affects development A formula calculating capacity obtained. Results calculated using are good agreement with those laboratory experiments.
