| Abstract | Computational Fluid Dynamics tools are increasingly used in the water sector, driven by computational advancements. However, the use of complex 3D models for large-scale hydrodynamics is limited by significant computational demands. A promising solution is hybrid 2D/3D modeling, which employs shallow water equations for less critical areas and 3D Navier-Stokes equations for regions requiring detailed flow analysis. This method offers a balance between computational efficiency and accuracy in crucial areas. The National Research Council Canada utilized physical modeling to assist in designing the Springbank Off-stream Reservoir's flood diversion structure on Elbow River, Canada. This involved assessing hydraulic performance through various flow scenarios and gate configurations essential for flood management. This study compares the hybrid 2D/3D modeling approach against fully 3D simulations using Flow-3D software for the Springbank project. By replicating laboratory-tested scenarios, the study evaluates the accuracy of hybrid model in predicting water levels and flow velocities. The results provide practical insights into the applicability of hybrid technique to large hydraulic projects, highlighting the impact of model configurations and parameters on performance. This study underscores the potential of hybrid model in optimizing computational resources while maintaining analytical precision in critical hydraulic analyses. |
