Hydro model helps fish avoid becoming dinner

Migrating salmon will soon be directed away from predatory fish near The Dalles Dam, thanks in part to a detailed 3-D computational fluid dynamic model created by researchers at PNNL and the Corps' Portland District. The Corps is building a concrete guide wall downstream of the dam's spillbays. The researchers' computer model showed such a wall would help move fish away from shallow waters downstream. Predatory fish like northern pikeminnow gather in the shallow waters and eat passing salmon. The new guide wall should direct salmon toward the Columbia River's deeper channels, where predatory fish are less abundant.

PNNL hydraulic engineer Marshall Richmond will explain the complex computational model that he and his colleagues developed during a presentation Wednesday at Waterpower XVI. The 3-D model was unusual because it included breaking waves on the surface, while most other river models use flat "lids" at the water surface. One of PNNL's supercomputers processed the model, while commercially available software helped create the model.

10:45 a.m.-12:15 p.m., Wednesday July 29, Session 3H: Improving Fish Passage through Modeling. Modeling Juvenile Salmon Egress Conditions in The Dalles Dam Tailrace Using Computational Fluid Dynamics. Authors: Marshall C. Richmond, PhD, Cindy L. Rakowski, William Perkins and John Serkowski, Pacific Northwest National Laboratory; Laurie L. Ebner, PhD, P.E., and Stephen J. Schlenker, PhD, P.E., U.S. Army Corps of Engineers.
