Title: Optimization of the Baffle Geometry of a Circular Culvert Outlet Structure to Maximize Energy Dissipation
Abstract: The primary objective of this study is to identify the optimal baffle height and placement for improving energy dissipation in a circular culvert dissipation system. By expanding the range of geometric configurations and flow conditions tested, this work aims to provide additional insight into the performance of staggered weir systems and contribute to improved design recommendations for culvert outlet protection. The present study builds upon the work of Zhang and Admiraal (2023) by modifying the experimental setup to allow greater flexibility in the placement of baffles within the dissipation system. A rail-based system was developed so that baffles could be positioned at multiple locations along the dissipation basin. This modification allows investigation of both baffle height and baffle location, enabling a more detailed evaluation of how these parameters influence energy dissipation in circular culverts.
