Chapter 14, Problem 4P

Please help as soon as possible  If the transmission coefficient for a breakwater is 0.26 and the resulting wave has a wave height of 7 meters what is the height of the design incident wave ?

Suppose an offshore platform is designed against the 200-yr wave (i.e., a wave height corresponding to a return period of 200yr), but it is only intended to operate for 30 years. What is the probability that it will be subjected to waves exceeding its design value during the 1st year of operation?

An offshore platform is built to withstand ocean wave forces.(a) The annual maximum wave height of the ocean waves (above mean sea level) is a random variable with a Gaussian distribution having a mean height of 4.0 m and a c.o.v. of 0.80. What is the probability that the wave height will exceed 6 m in a given year?(b) If the platform were to be designed for a wave height (above mean sea level) such that it will not be exceeded by ocean waves over a period of 3 years with a probability of 80%, what should be the platform height above the mean sea level? Wave height exceedances between years are statistically independent.
