FORECASTING OF TIDAL CURRENT FOR THE ENVIRONMENTAL MANAGEMENT AT COASTAL AREA

Abstract

The environmental management after human action is significant to eliminate and minimize the negative impacts on environment at developing area. In this study, the information distribution system of tidal current is proposed in order to support the environmental management in real time. Firstly, the numerical simulation model was developed to predict the temporal changes of tidal current and water stage at Isahaya Bay and Shimabara Bay, and the accuracy of predicted results was discussed in compared with the observed results. Following, the information system was built usingfree software. The predicted results of current by numerical simulation were distributed from thissystem by means of the internet in real time. This kind of system is likely to become very useful toolnot only for the water environmental management but also for the prevention of natural disastersaround the coastal area.
