 note = {application/pdf, 紀要論文, A new numerical method that is suitable for the calculation of flows in a very long region is proposed. The original flow is expressed as sum of the "main flow" obtained by solving one-dimensional Navier-Stokes equation analytically and their variations. Applying this method to incompressible flows in a very long pipe, we obtained good results. The method is now extended to the flow with free surface such as river flows. In this study, flows with free surface in very long and not flat wall regions are calculated and are examined for the effectiveness of the proposed method.},
