| Abstract: | The mean wavelength of ocean waves is an important environmental parameter in ocean engineering. Owing to the difficulty in its measurement, it is usually estimated from the mean wave period according to the theoretical relationship between the two wave parameters. However, the relationships that have been proposed are not very satisfactory. In this paper, some suggestions are made for improvement of the data analysis method by which the mean wavelength is estimated from surface elevation records. Laboratory experiments are conducted in a wind-wave flume, and a new relationship between the mean wavelength and mean wave period is obtained by the application of the improved data analysis method. The new relationship deviates from that of Xu et al. (1999) while it is very close to the one proposed by Kinsman (1965), although the last one is theoretically deficient. |
