Abstract: This study explores advanced design modification strategies to enhance stilling basin performance, focusing on energy dissipation, flow depth, and depth-averaged velocity across eight numerical models. This research involves both numerical as well as iterative method during the study. Overall 8 different Model were created, each model unique with different shape and placing of the basin appurtenances. After running the simulations and post-processing, Model 2, incorporating honeycomb baffle blocks, demonstrated the highest efficiency with 11.8% reduction in basin length. Model 3 followed closely, with notable performance at a 7.2% length reduction. Models 4, 6, and 8 showed promising results with a 5% length reduction, while Model 5 and Model 7 exceeded acceptable hydraulic limits that was considered even earlier. The honeycomb structures proved effective due to their labyrinthine configuration, which induced turbulence and dispersion, thereby enhancing energy dissipation. Furthermore, they facilitated basin size optimization, critical in spatially constrained environments. Fundamentally, the use of honeycomb baffle blocks appears as a powerful method for enhancing energy dissipation and optimizing stilling basin size. These results warrant more investigation into the use of honeycomb structures in hydraulic engineering.
