            Abstract

             The main objective of this work was to characterize four main coastal flooding events that occurred on the coast of Santa Catarina, Brazil between 2012 and 2020 and associate them with occurring active atmospheric systems, as well as data recorded in Epagri’s tidal network. All the flooding events took place in the Fall, Winter or Spring, presentng similar
            characteristics. The highest recorded tide values varied between 2.0 - 2.5m. What differed from one event to another was the number of coastal flood/event, ranging from 1 to 4. It was observed that extratropical cyclones located further South, in
            Uruguay, caused 4 and 5 floods per event, while extratropical cyclones located closer to Santa Catarina, between Uruguay and
            Rio Grande do Sul, 1 and 2. Considering 42 high inundatons, it was found that the tide percentage above the forecast tide ranged between 30-50%, 51-70%, 71-90% and >90%, in 12, 16, 13 and 1 episodes, respectvely.
