The present invention relates to a method for automatically predicting short-term coastal erosion by typhoon by using a seawater flow model such as an advanced circulation model, which simulates tides, typhoon, and tsunami, a sedimentation model such as an Xbeach model, which simulates costal erosion, and an active process program constructed with Perl or Phython. According to the present invention, tides are simulated in real time by continuously and repeatedly running the seawater flow model; the active process program accesses a typhoon predicting and warning institution such as a joint typhoon warning center (JTWC) in the U.S. and actively reads typhoon information; the active process program determines need of prediction of an impact of typhoon based on the read typhoon information and adds the read typhoon information to input information of the seawater flow model; and flow of seawater and coastal erosion and sedimentation thereof are automatically simulated. According to the present invention, impacts of tides and typhoon can be complexly applied to a numerical simulation of coastal erosion by typhoon. Therefore, coastal erosion can be precisely and rapidly predicted, and a coastal erosion forecasting and warning effect can be increased. |
