A visualization system was designed and established for numerical simulation of storm surges in the Pearl River Estuary. This system was achieved through hybrid programming, which combines the advantages of Fortran and geographic information systems （GIS） in terms of numerical calculation and visualization, respectively. The system encapsulates and integrates the numerical model for simulating storm surges based on the ELCIRC model, and provides a GUI interface, which is convenient for setting model parameters and boundary conditions. The system also includes functions such as dynamically displaying typhoon paths, drawing hydrographs of tides, visualizing current fields, and thereby making it easy for users to post-process and analyze calculation results. Application results show that the system is user-friendly and stable, and has high simulation precision.
