TL;DR: In this paper, a 3D numerical simulation of a steady, shallow turbulent flow around a groyne in a rectangular channel is presented, where a method used to track a moving surface boundary and to follow its evolution, using a one-phase 3D Reynolds solver with rigid grids, by means of a transient fraction of fluid or "porosity" field is applied.
Abstract: The three-dimensional (3D) numerical simulation of a steady, shallow turbulent flow around a groyne in a rectangular channel is presented. A method used to track a moving surface boundary and to follow its evolution, using a one-phase 3D Reynolds solver with rigid grids, by means of a transient fraction of fluid or “porosity” field is applied. Some results are compared with experimental data, such as the isolines of water depths and the mean velocity field. A comparison of the reattachment length prediction using the free-surface model and the rigid-lid assumption is given. Other results concerning the pressure field, turbulence, or shear stress distribution are presented and analyzed.

TL;DR: In this article, a system of plastic pipes which are anchored vertically in place along a shoreline by a concrete form that will position the pipes with a specific distance between pipes is described.
Abstract: A system of plastic pipes which are anchored vertically in place along a shoreline by a concrete form that will position the pipes with a specific distance between pipes. Once the pipes are positioned, a concrete cap will be poured to permanently secure the pipes, after which the concrete form can be removed and moved to a new location.
