Abstract: [1] In this study we investigate forced bars that form in a channel with periodic width variations. A depth-averaged two-dimensional (2-D) model incorporating a simplified correction for the helical flows induced by streamline curvature is used to obtain analytical solution of bed deformation. Flume experiments are conducted to verify the model results. With the correction included, the 2-D model will be comparable to the 3-D model. Because the no-slip condition is relaxed at the sidewalls, the model gives di…
