Comment on “On the role of diurnal tides in contributing to asymmetries in tidal probability distribution functions in areas of predominantly semi-diurnal tide” by P.L. Woodworth, D.L. Blackman, D.T. Pugh and J.M. Vassie [Estuarine, Coastal and Shelf Scie

The present paper comments on a recent publication by Woodworth et al. [Woodworth, P.L., Blackman, D.L., Pugh, D.T., Vassie J.M., 2005. On the role of diurnal tides in contributing to asymmetries in tidal probability distribution functions in areas of predominantly semi-diurnal tide. Estuarine, Coastal and Shelf Science 64 (2-3), 235e240.]. It is shown how tidal asymmetries associated with astronomical tides can be accounted for in an extreme sea level analysis, despite the difficulty of deriving probability distribution functions if a large number of tidal constituents are considered. The use of the term springeneap cycle in a diurnal tidal regime is discussed.
