HYDRAULICS OF RIGID BOUNDARY BASINS
A DESIGN PROCEDURE IS PRESENTED FOR A PARTICULAR TYPE OF ENERGY-DISSIPATING BASIN AT CULVERT OUTFALLS. THE BASIN FEATURES A SIMPLE GEOMETRICAL DESIGN, READILY ADAPTABLE TO FIELD CONSTRUCTION METHODS. IT UTILIZES ROUGHNESS ELEMENTS TO INDUCE A HYDRAULIC JUMP, THAT ENHANCES THE DISSIPATION OF ENERGY. A COMPREHENSIVE TEST PROGRAM WAS CONDUCTED TO DETERMINE THE ENERGY, MOMENTUM AND DRAG COEFFICIENTS NECESSARY TO ANALYZE THE BASINS ANALYTICALLY. THE METHOD OUTLINED IS GENERAL AND ALLOWS THE DESIGNER FLEXIBILITY IN HIS CHOICE OF DIMENSIONS. THE TEST PROGRAM INCLUDED STUDIES OF FLOW FROM BOTH CIRCULAR AND RECTANGULAR CULVERT OUTFALLS. DISCHARGES, RANGING FROM 6.75 TO 23.5 CUBIC FEET/SEC, WERE INVESTIGATED IN A 1.45-FT DIAMETER CIRCULAR PIPE AND A 1.25- BY 1.25-FT RECTANGULAR BOX. /AUTHOR/
