TL;DR: A review of the existing research on the interaction between a pipeline and an erodible bed exposed to waves and/or currents is presented in this paper, where the basic mechanism that leads to scour in two-dimensional and three-dimensional (3D) cases is first described, as deduced from small-scale laboratory experiments.
Abstract: A review of the existing research on the interaction between a pipeline and an erodible bed exposed to waves and/or currents is presented. The review covers three topics: scour, liquefaction, and lateral stability of pipelines. The basic mechanism that leads to scour in two-dimensional (2D) and three-dimensional (3D) cases is first described, as deduced from small-scale laboratory experiments. The onset of scour from piping and the developing tunnel erosion are among the processes described. The lateral expansion of the scour hole along the pipe is described, also based primarily on small-scale laboratory experiments. The state of the art of the mathematical/numerical modeling of the scour processes is presented. The associated self-burial of the pipe is described and compared to field observations. In addition to scour, liquefaction may also constitute a risk for pipeline stability. The cause of liquefaction and the resulting consequence for pipeline stability in a natural environment are discuss...

TL;DR: In this paper, the authors investigated the effects of the gap ratio on the scour depth and scour time scale of two identical pipelines in a tandem arrangement, where the two-dimensional Reynolds-averaged Navier-Stokes (RANS) equations, together with the conservation equation of the sediment mass are solved to simulate the flow around two pipelines and the evolution of the local scour profile below the pipelines.

TL;DR: A comprehensive review of scour around pipelines in the case of noncohesive sediment is presented in this article, which is organized in four main sections, namely the two-dimensional scour, the three-dimensional, the eifect scour on forces on and vibrations of pipelines and the mathematical modelling of the scour process.

The review is organized In four main sections, namely the two-dimensional scour, the three-dimensional scour, the eifect of scour on forces on and vibrations of pipelines and the mathematical modelling ofscour process. Over sixty works were included in the review.
