Abstract Stilling basin, a hydraulic structure that is commonly placed downstream of the spillways or outlets for decreasing the energy of the flow and consequently the erosion, and protecting hydraulic structures. This study investigates innovative methods to improve stilling basin performance through enhanced energy dissipation and reduced basin length using FLOW-3D 2023R2. Eight numerical models were analyzed, focusing on total energy dissipation and depth-averaged velocity. Five models outperformed the baseline (Model 1), where Model 6, incorporating honeycomb structures as the basin’s blocks, emerged as the most effective by achieving 67% energy dissipation. However, by reducing the length of stilling, Model 2 with honeycomb baffle blocks was able to reduce the basin length by 11.8% without exceeding the threshold limits. The results indicate that honeycomb structures enhance energy dissipation in stilling basins due to their labyrinthine structures, which promote numerous turbulences and energy dispersion and reduce the basin volume, offering a practical solution to hydraulic engineering applications. These conclusions may present significant implications for the enhancement of stilling basins and suggest further study on honeycomb structures from hydraulic engineering perspectives.
