The dispersion and dissipation properties of the discontinuous Galerkin method are investigated with a view to simulating wave propagation phenomena. These properties are analysed in the semi-discrete context of the one-dimensional scalar advection equation and the two-dimensional wave equation, dis

Abstract
The analysis of records, for the period 1962β1975, reveals that the wave height observations exhibit a seasonal variation in both the average value and the standard deviation. Examination of the seasonally adjusted wave heights indicates that these values may be approximately described by first order autoregressive time series models. the validity of these models is checked using statistical tests, comparing shortβterm forecasts of wave heights with actual observations and by simulating observations and examining the frequency and duration of storms and calm periods. Methods of improving the models for wave height are examined.
