Abstract

In current study, flow turbulence statistics generated around a circular bridge pier placed in a rigid bed channel for different flow discharges under constant flow depth are presented. Experimental work in the laboratory flume included measurement of velocity distribution around bridge pier using three-dimensional Micro-Acoustic Doppler Velocimeter to estimate the bottom Reynolds shear stresses, Velocity spectra, and Turbulence Kinetic Energy near the bed and mid flow depth. Power spectra analysis depicted that dominant of Reynolds shear stress, in the present study, is \(uv\) plane than other two planes at flume centerline. The strength of wake vortex is doubled for 27L/s vis-a-vis 22L/s.
