Culverts can disrupt natural stream flows and create barriers for fish due to high velocities, inadequate flow depths, and outlets perched higher than the natural streambed. CFD modeling can help an engineer create a more fish-friendly culvert as part of a new design or a retrofit. In this FLOW-3D HYDRO example, a dual-barrel culvert has an offset fishway design on one side and a flat slope on the other. Using CFD, you can fine tune the fishway design to meet the hydraulic needs of your local fish species by gaining detailed insights on the hydraulic performance of your design.
