Abstract: In this study, a two-dimensional advanced circulation model (ADCIRC) is used to simulate tides and storm surges around Taiwan's coast. The model was calibrated and verified with the observed tides and storm surges at four tidal gauge stations, which are the Taipei Tamsui, Taichung Harbor, Kaohsiung Harbor, and Hualien Harbor for historical typhoon events. The results showed a reasonable agreement between the simulated and the observed tidal levels and surge tides. The validated model was then used to assess the impact of sea level rise (SLR) on tides and surge heights. Four typical typhoon events under present sea-level condition, SLR 0. 87m, and SLR 1. 9m were used for model simulations. The simulated results showed that SLR increased tides and surge heights significantly at the Taichung Harbor, while there was a little influence at the Taipei Tamsui, Kaohsiung Harbor, and Hualien Harbor. The timing of the tide would arrive earlier by around 3. 5 hrs. The maximum increases of water level range from 0. 092m and 0. 137m under SLR 0. 87m, while they range from 0. 192m and 0. 248m under SLR 1. 9m at the Taichung Harbor
