seawall [Kamikubo et al. 2000] constructed at Kurahashi Island, Hiroshima
Préfecture at Japan and Fig. 9.3 shows the prototype and model scale
down version of curved seawall located at Galveston, Texas, USA [Coastal
Engineering Manual, 2006]. Photo 9.1 depicts the fabricated scaled down
model of seawall.
Fig. 9.2 Flaring shaped seawall.
Fig. 9.3 Galveston seawall.
The hydrodynamic scaling parameters are water depth, wave height
and wave period for a two-dimensional study. For a given scale factor A,
the hydrodynamics parameters are scaled down as follows,
Water depthTO — water depthp/A
5/10 = 0.5 m
Wave heightm — wave heightp/A
3/10 = 0.3 m
Wave periodm — wave period^/^/A
6/v/ÏÔ = 1.89 sec to 9/a/ÏÔ = 2.84 sec
