Wind induced coastal circulation in a shallow homogeneous-water under steady-state condition is investigated by employing a two-dimensional eddy viscosity model, taking account of the horizontal and vertical mixing effects.
In this study, an analytical solution of velocity and wind set-up is obtained on the basis of the Fourier integral method. Measurements of airflows, drift currents below an air-water interface, and water surface displacements under various wind condition have been made in a large wind flume. The current decreases rapidly immediately below the water surface, shifts below 10% of the water depth, and increases gradually with the pressure gradient. Although deviation of theoretical velocity profile is found in the near-surface region, the theoretical result shows good agreement in the whole flow layer.
