Abstract Submission: Dam removal projects are becoming increasingly common in the US due to many drivers including age, ecology, or sunsetting of purpose. A reservoir removal project in the southeast US seeks to replace the reservoir by a series of storm management measures to reduce flooding in the area. To minimize erosion and downstream impacts, the design of the hydraulic structures requires a careful evaluation of flow patterns, pressures and velocity fields. This design was evaluated using Computational Fluid Dynamics (CFD) with input boundary conditions from hydrological analysis. This work describes the process evaluate water flow in culverts and energy dissipators. We will describe the methodology we utilized to develop the stilling basin, determine wall locations and sizes to minimize scour potential and prevent flooding. Additional analysis will include a comparison of the energy dissipation performance under different flow rate scenarios. This work aims to illustrate practical applications of CFD techniques for hydraulic design of energy dissipation structures in non-conventional applications.
