Probable maximum tropical cyclone parameters for east and west coast of India

Storm surge simulation models require certain parameters for evaluating the worst possible event that could occur at a site with respect to return period. The most significant probable maximum tropical cyclone are pressure deficiency centre (?P) and wind speed (Vmax) during cyclone. In this study, would yield storm along Indian coasts of Arabian Sea Bay Bengal estimated. Datasets created based on various existing data archives each basin. datasets subjected extreme value analysis determining ?P Vmax parameters. fitted probability distributions (Gumbel, Fréchet, Weibull Log-normal) whose (scale, shape, location parameters) estimated using graphical (least square fit) numerical (order statistics approach) methods. A mean recurrence interval 1000 10,000 years is considered strategic structures. best fit distribution its obtained goodness criteria. resulting compared theoretical parameter values basin revised till an optimal set reached. shows represented by distribution. useful input model determine design basis flood level coastal sites.
