Abstract: Velocity, boundary shear stress and flow structure near the corner in rectangular open channels are investigated. Boundary shear stress was estimated from velocity distributions obtained by LDA measurements and by using Preston tube, and also calculated by Naot-Rodi model. Flow structure near the side-wall was visualized by the hydrogen bubble method. Results shows the secondary flow cells closely related to the distribution of boundary shear stress and the coherent structure in the wall region of the side-wall.
