Tidal Amplitude

Input the elevation difference between the high tide water elevation and the tidal mean water elevation (tidal amplitude). The fluctuating tidal water elevation is modeled as a cosine function with characteristics of a tidal range, amplitude and period. A typical high tide elevation for the 100-year storm tide in the Chesapeake Bay is 7.2 feet. If a low tide elevation of 0.0 feet is assumed for the analysis, the tide range is 7.2 feet, the mean tide water elevation is 3.6 feet ( ½ of 7.2 feet), and the tidal amplitude is 3.6 feet, the difference between high tide elevation and the mean tide elevation.
