Effects of Inlet Geometry on Hydraulic Performance of Box Culverts
APPENDIX B. INLET CONTROL COMPARISON CHARTS
This appendix includes all of the comparison charts used to evaluate the performance curves for various inlets tested under inlet control conditions. Charts from this appendix were selectively pulled into the text of the main body of this report to explain the analysis of data, but some of the charts included in this appendix showed such subtle differences that the authors chose not to overcomplicate the body of the report. Figures 94 through 100 are comparison graphs from experiments on the effects of fillets and bevels. Figures 101 through 122 are comparison graphs from experiments on the effects of multiple barrels. Figures 123 through 129 are comparison graphs from experiments on the effects of the spantorise ratio. Figures 130 and 131 are comparison graphs from experiments on the effects of skewed headwalls.
The following charts, figures 94 through 100, show the effects of fillets and bevel.
