WAVE CHARACTERISTICS IN FRONT OF VERTICAL SEA-WALLS

摘要

Wave characteristics in front of an emerged or submerged sea wall are studied by the vertical 2D numerical model NEWFLUME. Firstly the wave processes and the reflection coefficients in front of the sea wall are compared with experimental data, then the vertical distribution of maximal horizontal velocity u and vertical velocity v are compared with standing wave theory. It is found that the results have good agreement. Lastly the velocity field near the sea wall, the vertical distribution of horizontal and vertical velocity and wave pressure in front of the sea wall, and the vertical distribution of horizontal and vertical velocity at the wave node are studied and analyzed.
