摘要：	When the first fiill-depth filter barrier was deployed in Homer, Alaska in 1986 to protect a salmon spawning area from dredged sediments, potential effects on the barrier from near-shore tidal hydrodynamics were anticipated to be manageable due to the protected nature of the harbor. The full-depth barrier was designed, fabricated, and installed with the assumption that there was a reasonable risk that it may or may not provide adequate containment for the project to proceed to completion. Now, decades later, Computational Fluid Dynamics (CFD) modeling is a tool that can aid engineered design for more challenging sites to improve certainty in operational outcomes. CFD modeling is a branch of fluid mechanics that utilizes computers to analyze the behavior of fluids and physical systems. For bottom-sealed filter barrier designs, CFD modeling can portray probable flow patterns and their relationship to, and effect on, the barrier and its effectiveness. Often, key design parameters can be characterized, such as sediment settling, filtered sediment flushing, forces on the barrier at different tide levels and river current velocities and directions, and forces from eddy vortices and their impacts on barrier seal integrity.
