Summary

Introduction

Storm surges over the Atlantic Coast of South America have important effects in terms of coastal erosion, sediment dynamics and harbor activities, among many others. The aim of this project is to present a numerical system for storm surge forecasts in the South-Western Atlantic Ocean, basically from the northern Argentinean shelf (42◦S) to the Rio de Janeiro coast (21◦S), hereafter called SWAO region. The idealized system would be able to provide disturbances in the surface elevation and shelf currents fields related to the passage of meteorological systems over the studied area. It is very important to mention the cyclogenetic characteristics of the region of interest, which play an important role for storm surge events
