Example Problem II-8-2 (Continued)
Astronomical tide. A
probability distribution of
astronomical tide levels (Figure II-8-19) can be
obtained from:
(1) Harris (1981) for selected tide stations; (2) harmonic reconstruction of a tidal series (Part II-5); or, (3) to a good
approximation over all but the more extreme ends, statistical summarization of long-term water level
measurements.
Figure II-8-19.
Storm surge. Storm surge water levels (Figure II-8-20) can be estimated by the following steps:
(1) Develop criteria for identifying storm events, such as events with Hs $ 5 m and separated from each
other by 5 or more days.
(2) Identify all cases in the water level measurement record that meet the criteria in (1).
