DESIGN CRITERIA FOR CONTROLLED SCOUR AND ENERGY DISSIPATION AT CULVERT OUTLETS USING ROCK AND A SILL

CRITERIA ARE ESTABLISHED FOR THE EFFECTIVE DESIGN OF ROCK- BASIN ENERGY DISSIPATORS FOR FLOW FROM CULVERTS WITHOUT OR WITH A TRANSVERSE SILL. DESIGN TABLES HAVE BEEN PREPARED ON THE BASIS OF LABORATORY STUDIES WITH CULVERT MODELS. MODELS OF STANDARD END FLARES WERE USED TO SIMULATE THE CULVERT OUTLET CONDITIONS. STABLE ROCK SIZES AND BASIN GEOMETRY CAN BE DETERMINED USING THE DESIGN TABLES DEVELOPED IN THE STUDY. THE DESIGN TABLES ARE APPLICABLE FOR ANGULAR ROCK AS WELL AS ROUNDED ROCK. WORKED EXAMPLES USE THE TABLES FOR DESIGN OF ROCK BASINS FOR NO-SCOUR SITUATIONS AND CONTROLLED DEPTHS OF SCOUR. /AUTHOR/
