Three-dimensional (3D) computational fluid dynamics (CFD) models are increasingly being used to study forebay and tailrace flow systems associated with hydroelectric projects. This paper describes the fundamentals of creating effective 3D data visualizations from CFD model results using a case study from the Bonneville Dam. These visualizations enhance the utility of CFD models by helping the researcher and end user better understand the model results. To develop visualizations for the Bonneville Dam forebay model, we used specialized, but commonly available software and a standard high-end microprocessor workstation. With these tools we were able to compare flow patterns among several operational scenarios by producing a variety of contour, vector, stream-trace, and vortex-core plots. The differences in flow patterns we observed could impact efforts to divert downstream-migrating fish around powerhouse turbines.
