Abstract Submission: Representing hydraulic structures, including bridges and culverts has traditionally been a sticking point in 2 dimensional hydraulics. The complex flow patterns through, around and over these structures require a high amount of detail and effort. These complex flow patterns are both computational difficult and traditionally require significant manual manipulation. Constructing meshes and geometric definitions of these structures has required extensive labor and effort. This paper reviews methods for representing these structures parametrically and demonstrates how they can be generated and inserted into numerical simulations to accurately represent the flow through and over the structure including both pressure flow and overtopping flow. This technique has been successfully applied to bridges with complex pier configurations and multi-barrel culvert groupings.
Learning Objectives/Expected Outcome (Optional) : Participants will gain insight into how complex hydraulic structures can be represented with minimal parameters and incorporated into 2 dimensional hydraulic simulations. The United States Bureau of Reclamation model, Sediment and River Hydraulics - 2D is used as an example application platform.
