Conduct 1D and 2D Hydraulic Modeling of Traffic Rail for Design of TxDOT Bridges and Culverts

Researchers will develop a method to quantify hydraulic performance of different bridge and traffic rail types for implementation in 1D and 2D hydraulic modeling software to determine impacts on the surrounding floodplain during extreme flood events. The use of a previously developed rail rating curve and submergence model, combined with additional physical testing for newer rail types, will be incorporated into floodplain mapping software such as Hydrologic Engineering Center River Analysis Software (HEC-RAS) (1D and 2D) and culvert design software such as Hydraulic 8 Culvert hydraulics Analysis Program (HY-8). Researchers will develop generalizable modeling methodologies and guidance for various rail configurations under both 1D and 2D hydraulic modeling conditions to inform how to model different systems effectively and consistently.
