Global temperature is predicted to increase in the end of the century and one\nof the primary consequences of this warming is the sea level rise. Considering\nthe vulnerabilities on coastal systems and water resources, it is important to\nevaluate the potential effects of this rising in coastal areas, since the saline intrusion\non rivers would be intensified, leading to problems related to water\nquality. In this context, the present work aimed to verify saline intrusion\nchanges along an important river, S�£o Francisco Canal, located in Rio de Janeiro\nState, Brazil. For this purpose, a hydrodynamic modeling was performed\nusing SisBaHiA, considering different sea levels and tide conditions. According\nto the results, it was verified the intensification on saline intrusion and\nhigher salinity values due to a sea level rise of 0.5 m. These results show that\nnew licenses for water withdrawals must be carefully analyzed as the fluvial\nflow plays an important role to contain the saltwater intrusion on the studied\nriver. Accordingly, it is recommended the evaluation of climate change effects\nin order to choose best strategies to reduce coastal vulnerability, and the use\nof this theme on environmental licensing and territorial planning, integrating\nwater planning with coastal management.
