Evaluation of Hydraulic Effects of Culvert Safety End Treatments

Safety end treatments are installed on new and existing culverts to protect vehicular traffic if the vehicle should leave the roadway. Backwater effects associated with end treatment designs used by the Texas Department of Transportation have not been measured previously. Such measurements are provided through the hydraulic modeling program reported upon. Backwater effects are represented through minor loss coefficients (Km), which are found to be small with a representative value Km = 0.021 for all culvert end configurations investigated. Performance curves and coefficients are also presented for these different end configurations, which supplement results presented in 0-2109-1.
