A STUDY ON THE INTEGRATION GEOGRAPHIC INFORMATION SYSTEM WITH COASTAL OCEAN MODEL

摘要

The coastal ocean includes estuaries and the region between shorelines and the beginnings of deep ocean; thus numerical ocean models dealing with the coastal oceans need to consider a large range of phenomena and scales in both time and space, which should handle with a variety of physical processes of different scales. For these complex coastal ocean models, marine geographical information systems will be a challenging problem. The integration Geographic Information Systems (GIS) with coastal ocean circulation model is conducted to revitalize the use of geographical information and to help the understanding of ocean circulation pattern in coastal waters. A two-dimensional finite difference circulation model is used to simulate the tidal circulation in the Suyoung Bay in Busan, Korea. GIS, especially using ArcView SAW, is used to make input data of numerical model and also used for the visualization of model outputs on the ground of loosely coupling method. In this study, an electronic navigational chart (ENC), which can gives more accurate information in the ocean and coastal area than other digital information, is used as a base map of this integration. The integration can support the understanding of coastal ocean circulation with the help of GIS and can be applied in coastal management.
