Le Mehaute (1976)’s chart has been widely used in coastal engineering community because of its simplicity. However, there is a need to update this based on newly developed Stokes wave theory. This paper adopts Fenton (1999)’s 3rd order and 5th cnoidal solution for updating the chart. Fenton’s applicable range between two lines represented by m=0.5 m=0.96. For higher m values (region above red d...

independence of observations is a fundamental assumption in designing an x chart for individual observations. but unfortunately, the assumption of existence of independent data is not even approximately satisfied. in fact, there is one kind of autocorrelation in the data. this paper demonstrates, through simulating an ar(1) process, that the autocorrelation in the data has deep effect on x char...
