Wind induced waves are the most important phenomenon to be considered in the design of coastal and offshore structures. In many applications, it is necessary to use long-term wave data. The analysis of long-term wave data provides a theoretical distribution of probability of occurrence of wave parameters over several years. However, in many situations, there are no long-term measurements available and hence proper wave prediction models for hindcasting are required. Shore Protection Manual [1] and Coastal Engineering Manual’s [2] wave prediction methods are the most favorable methods in many countries and Iran. They can predict significant wave height and peak spectral period in fetch-limited, duration-limited and fully developed conditions. The purpose of this study is to evaluate the performance of these methods in prediction of wave parameters in Neka, Caspian Sea.
