A Review on Scour Modeling below Pipelines

摘要

Local scour below pipelines commonly occurs due to the erosivernaction of currents and waves. Such scour may cause pipeline suspension andrnultimately leads to pipeline failure. Over the last three decades, both physical andrnnumerical modeling of pipeline scouring in steady currents and waves has beenrndeveloped for better understanding of local scour. In this paper, a review on scourrnmodeling below pipelines is presented from both physical and numerical modelingrnaspects. Advantages and limitations of both scour modeling methods will be provided.rnFuture development of scour modeling below pipelines will also be discussed.
