| Abstract | Distributions of wave height and wave set-up on the nonuniform bed configurations, namely, the step type and bar type in
the surf zone are investigated both in a numerical mode ling and
an experiment. Theoretical considerations are bas e d on the
linearized breaking wave method . The general two-dimensional
basic equations combining effects due to refraction, diffraction,
shoaling and wave breaking are introduced in form of the first
order equations. A numerical model for prediction of wave height
and wave set-up distributions in the surf zone is proposed by
using the finite difference method . Results from the experiments
are presented in terms of distributions of wave height and wave
set-up along the beach profiles. The characteristics of wave are
unique for each type of the beach model. The distributions of
wave heights show rather good results for every test runs whil e
that of the wave set-up show highly variation of the observed
data. This may be due to the effect of voltage drop from the wave
gauge . However, trends of the major group of all the data are
quite reasonable. With the modification of the experimental
results on the the offshore boundary condition for wave set-up ,
the results are much better. Comparison be tween the predicted and
experimental values for the wave height distributions s how s
rather good prediction al though there are some under estimated
values around the breaking point due to the nonlinearity of the
real wave in the surf zone . For the distributions of wave set-up,
using only the trends of the major groups of the experimental
results in the comparative plots with the predicted values, a
reasonably good prediction was found. |
