NONENLARGED BOX CULVERT INLETS - FIFTH PROGRESS REPORT ON HYDRAULICS OF CULVERTS, NATIONAL BUREAU OF STANDARDS REPORT 9327

THE HYDRAULIC CAPACITIES OF BOX CULVERTS OPERATING WITH FLOW CONTROL AT THE INLET WERE INVESTIGATED BY USE OF SCALE MODELS. THE EFFECTS OF BARREL SHAPE, WINGWALL FLARE ANGLE AND SKEW OF INLET ON CAPACITY WERE ESTABLISHED FOR PRESENT TYPES OF BOX CULVERTS AND EXPRESSED IN ENERGY EQUATIONS RELATING RATE OF FLOW TO BARREL DIMENSIONS AND HEADWATER DEPTH. IMPROVED CAPACITY WAS OBTAINED BY USE OF BEVELS AT THE INLET EDGES AND BY RELOCATION OF WINGWALLS. THE DIMENSIONS REQUIRED FOR IMPROVEMENT OF CAPACITY ARE REPORTED. /BPR/
