A $7$ s$,2\mathrm{.}5$ m high deep water wave approaches the shore in a normal direction. At a

distance of $300$ m from the shore a $700$ m long breakwater is constructed parallel to the shore

and the area leeward of the breakwater is dredged to a depth of $5$ m$,$ which is the natural depth

at the breakwater. What is the maximum wave height that will occur at the center of the

breakwater on the leeward side?

If the deep water incident wave direction is $30$o off a line normal to

the breakwater axis and the nearshore bottom contours are all straight and parallel to the shore,

what is the maximum wave height at the center of the breakwater on the leeward side? Draw

the wave crest pattern in the vicinity of the breakwater. Assume the breakwater has a reflection

coefficient of zero.
