Abstract: Recent experimental evidence of the effectiveness of submerged vanes in reducing bank erosion in river bends has led to attempts to develop a quantitative design procedure. The basis for design computations is an ordinary differential equation expressing torque equilibrium about a longitudinal axis passing through the centroid of the section. The torque generated by horizontal vane lift force compensates for the contribution nor mally supplied by secondary-flow bed shear stress, ultim ately permitting equilibrium to exist with a flatter transverse bed slope. Elements of the theory are briefly decribed, and its use in calculating a vane configuration for a bend in the Yukon River is presented.
