Abstract: This project is aimed at studying the complex flows at District's culverts structures by Computational Fluid Dynamics (CFD). Despite existing rating algorithm works reasonably well for flood control purpose, more accurate and detailed flow parameters need to be estimated for environmental compliance at many critical District sites. Hence, compared with direct point measurement, it is much more efficient to adopt reliable numerical simulation to provide information over the entire flow field. Following the literature survey (Task 1) conducted in FY06, we conclude that it is feasible to utilize CFD as an effective tool to improve the existing rating curves based on distributed approach. In FY07, we propose to continue this study for Task 2: data gathering and scenario selection for CFD modeling and Task 3: CFD model selection and evaluation. In Task 2, we will consult scientist at SFWMD for realistic field site and flow data. In Task 3, we will focus on evaluation and inter-comparison of turbulence closure models, grid generation capability and free-surface tracking scheme.
