EXPERIMENTAL INVESTIGATION OF FORM OF BED-ROUGHNESS

EXPERIMENTAL OBSERVATIONS REGARDING MEAN VELOCITY DISTRIBUTION, ANGLE OF FLOW, STATIC PRESSURE DISTRIBUTION AND LONGITUDINAL TURBULANCE INTENSITY ARE ALL MADE ALONG A TYPICAL WOODEN WAVE IN THE DOMAIN OF RIPPLES AND DUNES OF RIVER FLOW. THE WAVE WAS PRODUCED IN A LOW-TURBULENCE WIND TUNNEL AND THE MEASUREMENTS WERE MADE BY HOT-WIRE ANEMOMETRY IN AN AIR MEDIUM. FROM THESE OBSERVATIONS SKIN FRICTION COEFFICIENT, FORM DRAG, AND OTHER BOUNDARY LAYER PARAMETERS HAVE BEEN EVALUATED TO HELP ANALYZE THE PROCESS OF SEDIMENT TRANSPORT. /ASCE/
