Wave Overtopping and Coastal Structures - Essay Example Nevertheless, the other formulae, listed hereafter, also still merit some consideration and they have been used in this part of the paper, in conjunction with that of Shao, 2006. The motive this time is to use wave and structural data other than that of Shao, 2006, to investigate what wave parameters pose the maximum threats to coastal structures with given parameters. This, it is sincerely believed, will allow future researchers to better prepare for dangerous and possible wave overtopping real-time events. It is significant that overtopping discharge and, in essence, individual overtopping volume in effect, are highly sensitive to even very small changes in seawall geometry, local bathemetry and wave climate (Wallingford, 1999). The strategy this paper adopts to investigate influence of wave parameters on seawall efficiencies is simple. A number of variant sets of parameters are used to test mean overtopping discharge possibilities. ... The strategy this paper adopts to investigate influence of wave parameters on seawall efficiencies is simple. A number of variant sets of parameters are used to test mean overtopping discharge possibilities. Mean Overtopping Discharge: 1. An initial seawall slope of 1:5 is taken with wall height (taken as the wall freeboard for crest above still water level) = 1m and wall length () = 5.6m. The significant wave height () is kept at 0.85m, while the wavelength is assumed to be 4.25m. The wave period (), though, is varied to 1.2s. With this configuration, the Wallingford overtopping volume model is applied. It is also assumed that there are 10 waves in a series. = .2888 (Equation valid as per Wallingford, Box 3.1, p. 10, 1999; for 0.05
