Kweon, H.M.; Choi, Y.H.; Kang, J.W.; Lee, W.D.; Hong, S., and Park, S.K., 2014. Reduction of the expected wave overtopping probability and its rate upon seawall utilizing STB(Steel Type Breakwater).
Wave overtopping damages at seawalls, which separate lands from coastlines, are increasing as residences and commercial facilities are recently becoming concentrated near coastlines. The wave overtopping volume or probability can be decreased by increasing the crest elevation or width of the existing structure. Crest elevation or width increase of structures like seawalls, however, violates the citizens' view rights, and public water reclamation leads to an increase in the construction cost. The STB (Steel Type Breakwater) is a submerged-type non-reclamation structure, can be quickly constructed at a very low cost, and incurs almost no additional responding costs for the sea level rise. The feasibility of the new economical areal protection combination construction method that can reduce the EWOP (Expected Wave Overtopping Probability) without violating the citizens' view rights was validated in this study.
