NONENLARGED BOX CULVERT INLETS

THE EFFECT OF VARIATION IN THE DIMENSIONS OF BEVELED LEADING EDGES ON THE DISCHARGE CAPACITY OF BOX CULVERT INLETS OF RECTANGULAR CROSS SECTION IS INVESTIGATED. IT IS DEMONSTRATED THAT THE EFFECTIVE CONTROL SURFACE OF A BEVELED EDGE MAY BE EITHER THE FACE OF THE HEADWALL OR THE BEVELED SURFACE OF THE EDGE GEOMETRY, DEPENDING ON THE RELATIVE DIMENSIONS OF THE BEVELED EDGE. THE BEVEL DIMENSIONS REQUIRED TO ENSURE BEVEL SURFACE CONTROL ARE DETERMINED. THE DEPENDENCE OF THE DISCHARGE COEFFICIENT ON THE DIMENSIONS OF THE BEVELED LEADING EDGE AND ON THE CROSS-SECTIONAL SHAPE OF THE BARREL IS DEMONSTRATED. METHODS FOR ESTIMATING THE CAPACITY IN SUBMERGED ENTRANCE FLOW OF BOX CULVERT INLETS OPERATING IN ENTRANCE CONTROL ARE DEVELOPED FOR VARIOUS BEVELED LEADING EDGE GEOMETRIES. /ASCE/
