NBS STUDY AIMED AT IMPROVING CULVERT PERFORMANCE

A STIMULUS FOR HYDRAULIC STUDIES OF CULVERT PERFORMANCE HAS BEEN PROVIDED BY THE INCREASED COST OF ADEQUATE CULVERT PROTECTION OF HIGHWAY FILLS. SIGNIFICANT SAVINGS MAY ULTIMATELY RESULT FROM HYDRAULIC PERFORMANCE STUDIES OF PIPE AND BOX CULVERTS. TAPERED INLETS, FALL CONCENTRATION AND BEVELED EDGES HAVE RESULTED IN A FLOW CAPACITY TWICE AS GREAT AS THAT OF CONVENTIONAL CULVERTS. IMPROVED DESIGN OF THE INLET STRUCTURE IS SHOWN TO DOUBLE THE WATER-CARRYING CAPACITY BY USE OF SOME OF THE DISCUSSED FEATURES: A BEVELED LEADING EDGE AT THE INLET FACE, A TAPERED OR CONE-SHAPED INLET AND A FALL CONCENTRATION IN THE INLET STRUCTURE. MODEL TESTS WERE CONDUCTED ON THESE CONFIGURATIONS AND RESULTS ARE APPLICABLE TO THE DESIGN OF HIGHWAY CULVERTS.
