ANALYSIS OF HURRICANE TIDES AT PADRE ISLAND, TEXAS

Abstract

To establish design data, a study was undertaken to determine expected hurricane tide elevations, durations and frequencies of occurrence for events of various magnitudes in the vicinity of a proposed development at Padre Island, Texas A set of synthetic hurricanes with selected sizes, translation speeds, wind fields, and pressure patterns were generated corresponding to various frequencies of occurrence of the CPI Two numerical computer models were developed to determine the offshore surge hydrograph and to route the surge through the bay waters for each synthetic hurricane moving directly over the site Results included storm tide hydrographs at selected locations near the development Synthetic storms were also routed across the coast at locations north and south of the site and storm hydrographs again computed.
