A numerical model is proposed to investigate the finite amplitude bed topography and maigration characteristics in meandering channel. Migration characteristics of bar in meandering channel is investigated. The effects of geometric and hydraulic factors for finite amplitude bed topography are investigated using the proposed numerical model. By the results of the numerical experiment, a series of figures are presented, which show the effects of each parameter to the finite amplitude bed topography. A practical formura is proposed to estimete the finite amplitude bar height.
