ABSTRACT
A study about coastal flooding by wind setup at the shore zone of the Batabano Gulf, under influence of south wind events, is presented. The south wind events are observed in winter, when the extratropical cyclones move over the Gulf of Mexico or the south coastal zone of United States. The Batabano Gulf is a shallow water enclosed space and this geographical configuration is favorable for sea level rise by wind setup. Applying numerical methods, the sea level rise in present and future climatic change sceneries was simulated, taking into account the Oceanological Institute and the Inter - government Panel for Climatic Changes evaluations. The returned function for south wind events was obtained. The results indicate that sea level rise by wind setup at the studied area is significant when the wind velocity is equal or over 10 m/s. If the extreme middle sea level increase in 1 m due to climatic change, the sea level rise by wind setup can decrease in order of 10-2 but the horizontal land penetration could increase between 1 and 3 Km.
