DESIGN CRITERIA FOR EROSION PROTECTION AT THE OUTLET OF CULVERTS

STUDIES WERE MADE OF DUMPED ROCK TO CONTROL EROSION AT THE OUTLET OF CULVERTS. THE VARIABLES INCLUDED FULL AND PART- FULL FLOW FROM CULVERTS OF DIFFERENT DIAMETERS ONTO BEDS OF DIFFERENT SIZES AND SHPAES. EXPERIMENTS DETERMINED THE VELOCITY REQUIRED TO CAUSE INCIPIENT MOTION OF THE BED, THE SIZE AND SHAPE OF THE ULTIMATE EQUILIBRIUM HOLE, THE TIME RATE OF PROGRESSION OF EROSION, AND THE PROTECTIVE EFFECT OF SUBMERGENCE AND DENSE PACKING OF THE BED. /BPR/
