Abstract: For the tidal current simulation, proper estimation of meteorological conditions, such as spatial and temporal variation of wind, atmospheric pressure and so on, are necessary. In many countries as well as Japan, several kinds of meteorological simulations are being carried out, and predicted results are used for the daily and long-term weather forecast and the natural disaster prevention. Recently, these results are available through internet in real time. This paper presents the outline of tidal current simulation using forecasted weather data. In this simulation, sea level departure caused due to the meteorological variation at open boundary is estimated by artificial neural network (ANN). Tidal current simulation is carried out for Shimabara Bay, Japan, and the effects of wind blowing over the water surface on tidal motion of this bay are shown.
