Evaluation of Energy Dissipation Using Different Drop Broken‐Back Culverts Under Pressure Flow Conditions
Hydraulic jumps formed in broken‐back culverts were investigated experimentally by using energy dissipation devices. Additional examination measured the reduction in scour downstream of different‐height broken‐back culverts by forming a hydraulic jump inside the culverts. A broken‐back culvert model in the laboratory represents 150 ft in the field. The results were analyzed in terms of the inlet Froude number and different drop heights of broken‐back culverts. The calculated efficiency of energy dissipation in the culverts ranged between 55 and 90%. The dimensionless charts were created on the basis of data collection showing the relationship between the different relative drops and optimal sill height, optimal sill location, total head losses, optimal end sill, Froude number, and efficiency of hydraulic jump. The objective of this research was to obtain the maximum energy dissipation in different drop heights using analysis of dimensionless relationship charts.
