GIS, with its powerful spatial data storage, processing and analysis functions, has been widely used in many engineering modelling and calculations. FVCOM model is an ideal model for offshore hydrodynamic calculations, providing a better adaptability in the coastal region with complex geometry and ensuring the conservation of momentum, mass, and energy in a unit volume. A case study of Bohai Sea was conducted based on GIS coupling with FVCOM model, which provided a pre-processing of spatial data management, automatic mesh generation and data extraction with a result of improving the efficiency of modeling, debugging and pre-processing. In the post-processing, the NetCDF and Geodatabase spatial database format were used to store multi-dimensional calculation data. The calculation results of the tide and salinity of the Bohai Sea were also verified and analyzed. The results of analyses show that the GIS coupled model can facilitate data handling and greatly improve the modelling efficiency with clear and vivid visualization of the results, reflecting the physical characteristics of the study area, and providing decision-making support of data and theory for coastal environmental management.
