Abstract

This study assesses the capability of the ADCIRC and coupled
ADCIRC+SWAN models in simulating typhoon-induced storm surge and
significant wave heights along the coast of Taiwan. Three typhoon events in 2024,
Gaemi, Kongrey, and Krathon, were selected based on their different tracks and
wind characteristics. The simulations were evaluated using observed tide gauge
data from four stations (Taipei, Taichung, Kaohsiung, and Hualien) and buoy data
from Fuguei Cape, Taichung, Xiaoliuqiu, and Hualien. ADCIRC-only simulations
were able to capture the general pattern of tidal and surge behavior at most stations,
with the best agreement found at Taipei and Taichung. Slight underestimations of
peak surge heights were observed at Kaohsiung and Hualien, likely due to
unresolved wind gradients and the absence of wave effects in standalone ADCIRC
runs.
