Stochastic evaluation of probable maximum storm surge

STOCHASTIC EVALUATION OF PROBABLE MAXIMUM STORM SURGE 

Time series from several locations should be correlated, thus providing a basis for developing a synthetic time series that is valid over a longer interval than the time span of the local observations. The use of time series from other representative hydrometric stations will broaden the basis of the analysis and make it more reliable. 

By working with actual surge levels as basic parameters, the different factors relating to the intensity, path and duration of storms are implicitly taken 

The still water level is the elevation that the surface of the water would assume if all short period wave actions were absent. 

Stochastic analyses do not usually give adequate information about the physical validity of the results obtained. For this reason a simplified deterministic study should be carried out to check the results of a stochastic analysis, and a physical model appropriate for the region should be used. Such a check should consist of two steps
