Abstract

The experimental and theoretical study in a curved channel are performed on the flow and bed profiles near the overhanging bank that is often seen in the natural bank and bank with common reed. As the results of this study, the overhanging bank shows the control of secondary flow around the outer bank and the resulting scouring rate. Those results indicate that k-ε model is applied for solving flow around overhanging bank, and the solutions of this model are in good agreement with the experimental results of the shear stress distribution, flow and bed profile in the curved channel with overhanging bank.
