Descriptions
The flow near the shoreline is deeply related to the growth and survival of living things of a tidal flat. Therefore, prediction of the coastal flow due to tides is important. In this paper, the cross-shore current due to the tides is studied combining the continuity equation for one dimensional flow and the water level change. The equations for line flux and the depth averaged velocity were btained by integrating the continuity equation from the instantaneous shoreline to the arbitrary position beyond the shoreline. Samples of calculation indicate that the stagnation of the flow occurs in front of the vertical structure constructed on the tide flat.
