B

Irregular waves with significant wave height 1.3 m in 5 m deep water are propagating in a

perpendicular direction (0) towards a vertical caisson situated on top a slope as shown above

(there are no armor blocks). Details of the structure and bathymetry are further summarized in

the given table. Assume a water density of p= 1025 kg/m³ when solving this problem. Note that

water is present on both sides of the caisson.

a) Determine the water depth (h) at a distance of DSM, from the caisson.

b) Based on the significant wave height provided, determine the design wave height (I) and wave

period (7)

c) Determine the wavelength L.

d) Using Goda's original equation, determine the wave pressures P. P. P. and P

e) Determine the total horizontal wave force (F), uplift force (F), and overturning moment (M₂).

f) Determine the factors of safety against overturning and sliding.
