Storm Surge Simulation using POM and a Revisitation of Dynamics of Sea Surface Elevation Short-Term Variation.

Abstract

Wehave done several three−dimensional numerical stomsurge simulationsusingtheterrain− following Princeton oceanmode1（POM）withhorizontallyuniformstratification inthe area ofTosa Bay（maximum depth二4，800m）．Results show slightly larger peak surges wi蜘finer vertical resolution or stronger stratification．We report the effects of the vertical mixing fom on the SimUlated Sea leVel． The balance of forces in momentum equations are studied in some detaiL A simple explanation is proposed as to expla圭n why larger peak surges are found as vertical resolution becomes finer．
