Abstract: abstract:In this study we developed a two-dimensional numerical model to predict tide and typhoon surge around Taiwan. The storm surge associating with a typhoon approaching to Taiwan is one of the main causes that floods frequently occur in the low land areas in certain exposed coastlines. The finite difference method is used to solve the control equations. The model area is 900 km× 900 km, and Taiwan lies in the central part of model. The tides at open boundaries of model are the driving forces for tidal flow inside the model. The tides at model boundaries are calculated through harmonic method making use of the principal tidal constants of M2, S2, K1 and O1 partial tides. Air pressure gradient and wind stress are considered as the driving forces for typhoon surge in this model. A circular storm model of Jelesnianski (1965) is taken here as the typhoon model. The combined effect of typhoon surge and tide will be studied in this model. The computed results are compared to the observed ones at some tidal stations around Taiwan. For strong wind region near typhoon center the computed results agree well with the observed data in most tidal gauge stations. For some typhoons, where the winds are weak and unstable, the computed results are poorly comparable to the observed ones. This may be due to the discrepancy between circular typhoon model and real typhoon.
