| Abstract: | Significant wave height is an important criterion in designing coastal and offshore structures. Based on the orthogonality
principle, the linear mean square estimation method is applied to calculate significant wave height in this paper. Twenty-eight-year
time series of wave data collected from three ocean buoys near San Francisco along the California coast are analyzed. It is
proved theoretically that the computation error will be reduced by using as many measured data as possible for the calculation
of significant wave height. Measured significant wave height at one buoy location is compared with the calculated value based
on the data from two other adjacent buoys. The results indicate that the linear mean square estimation method can be well
applied to the calculation and prediction of significant wave height in coastal regions. |
