Abstract : A computer simulation model is used to study the relationships among barometric pressure, wind, waves, longshore currents, beach erosion and bar migration on the eastern shore of Lake Michigan. Harmonic trend analysis with a single Fourier series is used to represent the major trends in weather and wave parameters. In the simulation model, barometric pressure is plotted as a function of time and longshore current velocity is computed as the first derivative of barometric pressure. Breaker height closely approximated a modified form of the second derivative of barometric pressure. Daily profiles provide data for nearshore topographic maps. (Author)
