Abstract

In theoretical study, when the maximum run-up on seawall was happened, the shape of the run-up wedge is assumed to be a parabola with its vertex at the bottom of the first wave trough. The another assumptions are the conservation of mass and momentum. In model test, four kinds of dyke slope (1:0.5, 1:1, 1:2, 1:3 )were choiced and the tests of the wind speed from 0 to 16 m/s accompany with a range of wave steepness were completed. The experimental data shows that the general form of the equations to developped was correct. Comparison of the theoretical estimations and the experimental data are coincident very well. Besides, the relation coefficient between the exponential value n of the parabolic runup shape with the surf parameter ( | ) was ranged in 0.19 to 0.65 in different kinds of dyke slope have been found also. At last, in general speaking, in spite of the strength of the wind speed, the relative run-up becomes the biggest when the dyke slope was 1:2.
