Tidal Current Simulation System Applied Geographic Information System

Abstract

When a big structure will be built in a bay, it is needed that environmental prediction must be carried out. In the prediction of a water quality or an ecosystem for the purpose of environmental assessment, simulation models must be managed to use. Here, tidal current simulation is taking sufficient part in these simulation models for prediction. However, technical skill is especially needed in tidal current simulations, since horizontal and vertical (depth direction) geographical features are complicated, input data is difficult and large in quantity, and calculation technique is also expected. The people without technical knowledge are difficult to use this simulation. On the other hand, geographic information system (GIS) has been applied to various fields by the powerful ability. In this paper, our object is to develop the simulation system which is applied GIS to a tidal current simulation program. Our major points of this developed system are to be able to execute a tidal simulation efficiently and simply. And also, we can easily grasp the phenomena in target area by visualized simulation results as output.
