Wind waves are capable of dealing damage to hydraulic structures. In the ultimate case, the loads never exceed the strength of the structure. Unfortunately it is often impossible (or uneconomical) to design a structure that will fit this requirement. That is why structures are designed with a certain allowable probability of failure, displayed by the overlap of the probability distribution functions in the figure. To design a structure with a certain probability of failure, the probability distribution function of both the load and the strength should be known. The load of waves can be determined using wave energy and the frequency of waves which can be determined using prediction formulas. The inaccuracy of the parameters in these formulas play a major role in the probabilistic design of structures, because the distribution function of the wave-load is directly influenced by it. There are plenty of prediction formulas for wind waves, but only a few formulas exist for wind waves in water of finite depth. This paper is intended to determine the accuracy of the fixed parameters in the Young and Verhagen formula for the height of wind waves in water of finite depth.
