Abstract Submission: There are multiple tools available to the hydraulic engineer for sizing and designing culverts and stilling basins. These design methodologies are well established, however, they typically cannot be used where site conditions deviate significantly from assumptions. For a recent project, CFD modeling was used to advance the design of a complex, multi-section culvert and energy dissipation structure in the western US. The evaluation resulted in critical design adjustments to avoid of poor hydraulic and air entrainment conditions which were identified with the CFD model. Improvements to the pipe sizing, manhole and alignments were made which resulted in satisfactory hydraulic conditions. The inlet trash rack was also evaluated and compared against recent work by others to determine the potential for unsafe conditions near the inlet. This project highlighted the complimentary use of typical design standards, 1D calculations, and 3D CFD analysis.
Learning Objectives/Expected Outcome (Optional) : The primary objective is to demonstrate the complimentary use of typical design standards, 1D calculations, and 3D CFD analysis for culvert or hydraulic structure designs.
