It is important to estimate the quantity of wave run-up and overtopping in
seawall design. Previous study on the investigations of run-up is carried out mostly in
the laboratories, it seldom perform in field measurements. About previous wave
run-up equation can¡¦t accurately estimate run-up elevation. According to run-up data,
this study hope that it can make the formula to meet the actual local situation. It can
have a better reference by designing coastal structures.
This paper study wave run-up during five typhoons by
Kalmaegi ,Fung-Wong,Nuri, Hagupit,and Jangmi. It measuring wave height , water
level,and topography.
These data show that the run-up elevation in bay higher than in breakwater. It
shows that wave pass through a submerged breakwater can decay wave height.
Analysis of measured data and found that when the wave height is about 1~4
meter with 1/(H0/L0)0.5 has a good correlation. It similar to some past researchers.
Experience equations close to measured value when wave height smaller than 4
meter. When wave height more than 4 meter, the empirical prediction value is larger
than measured value. Wave run-up doesn¡¦t have good theory, and experience
equations different about every field. The empirical equations depends on the scene to
investigate the effects of various parameter.
