ABSTRACT
ABSTRACT: In the present study, we highlighted a transition region from the straight to meandering compound free-surface flows, in which coherent structures of horizontal vortices may be changed due to the space-time variations of streamwise velocity. So, 3-D velocity measurements were conducted by using 3-D electromagnetic velocimetry. The bed-shear stress, secondary currents, and Reynolds stress distributions were investigated in meandering compound open-channel flows.
