Two-Year Flow Scenario Modeling and Simulation of Waller Creek Intake CFD

This preliminary report presents the modeling and simulation results of a two-year flow scenario for the Waller Creek Intake using Computational Fluid Dynamics (CFD) techniques. The analysis includes detailed plots of velocity contours and isosurfaces at various elevations and locations around the flood control turning vane and morning glory spillway. This study aims to evaluate the flow dynamics, enhance understanding of hydraulic behaviors, and inform future design and operational strategies for flood control. Results are displayed at 250 seconds across multiple slice planes.
