This scientific paper presents a comprehensive study on the Computational Fluid Dynamics (CFD) modeling of water jet formations at dam bottom outlets, with a focus in the comparative analysis of CFD results against actual drone footage captured on-site. The research commences with the development of a detailed CFD models, encompassing the geometric and hydraulic characteristics of the dam bottom outlet structure. Special attention is given to incorporating boundary conditions and numerical schemes that accurately simulate the water jet formation process. Computational simulations are conducted for a range of operational scenarios i.e. bottom outlet gate openings. To validate the CFD results and prove their applicability, a field campaign is carried out, involving the use of camera equipped drone and one stationary camera, to capture real-time footage of water jet formations at dam bottom outlet. The drone footage provides invaluable visual data that allows a direct comparison between the CFD predictions and actual onsite observations. The comparative analysis involves a quantitative assessment of key parameters, such as jet velocities, trajectories, flow patterns etc. Discrepancies between the CFD predictions and real-world observations are analyzed to identify potential areas for model refinement and future improvement. The results of this research contribute to a better understanding of the hydraulic behavior of dam bottom outlets. By leveraging advanced CFD modeling and real-world drone footage, this study provides a holistic approach to studying water jet formations at dam outlets, bridging the gap between numerical simulations and empirical observations in a complex hydraulic environment.
