The experimental results of 3-dimensional flow field and bed evolution around spur-dike is presented. And numerical simulation method for 2-dimensional bed evolution based on 3-dimensional flow model which is considered vertical pressure distribution is proposed. This numerical model takes into account non-equilibrium sediment condition. This model is applied for the experimental results and the simulation results are in good agreement with the observed data to some extent.
