영문 초록

This study investigated the applicability of four empirical equations (Morihira et al., 1967; Goda, 2010; Jensen, 1984 and Bradbury et al., 1988; Pedersen, 1996) suggested for estimating the horizontal wave force on the crown wall of sloping breakwaters. For the two exemplary cross sections of the breakwaters whose geometry are apparently different each other, the estimates of horizontal wave force calculated by the four equations were compared. The values of estimated wave force showed considerable discrepancy among the equations for each of the two exemplary breakwater cross sections, respectively. In addition, the relative magnitude of the wave force was quite different according to the breakwater geometry as well as the design wave condition. In general, Morihira’s or Goda’s formulae produced larger estimates of the horizontal wave force than Jensen/Bradbury’s or Pedersen’s formulae if the wave period (or wavelength) is comparatively short. In contrast, exactly opposite result was obtained when the wave period or wavelength is comparatively long. Further detailed study based on physical experiments is required to examine the applicability of the four empirical equations considered in this study more thoroughly.
