Abstract: This paper presents an estimative of coastal flooding level values distribution along the Brazilian coast by using reanalysis data and by simulating wave propagation with Snell approximation. The coast was divided into 24 zones and flooding levels series were calculated for each one. Mean and extreme distribution show higher flooding levels occurring in northern coast (3 m higher than beaches in central coast) followed by the southern coast (1 m higher than central coast). High values obtained on north region were associated with greater tidal elevations (maximum values > 3 m) while higher values in south were related to greater wave heights and higher storm surge elevations (~2 m and >7 m respectively). A comparison between beach types were also conducted and demonstrate higher values of flooding levels during reflective conditions (0.3 m higher for a specific beach condition), as a result of the runup model applied. Although simplifications were used to calculate this large scale variation of the flooding level along the coast, the results partially presented here can be of large usefulness in pre-design phases of coastal projects and in preliminary risk analysis.
