GPU-IOCASM（GPU加速的隐式海流和风暴潮模型）

This project has independently developed a GPU-accelerated numerical simulation and forecasting code for storm surges, with fully independent intellectual property rights. The code is designed to meet the demand for rapid simulation of coastal storm surges under typhoons, strong winds, and abrupt atmospheric pressure changes. It adopts the two-dimensional shallow-water equations as the governing equations and incorporates key dynamical processes, including astronomical tides, wind stress, atmospheric pressure, bottom friction, the Coriolis force, and tidal forcing at open boundaries, thereby enabling comprehensive simulation of the entire tide–storm surge process. Building on this work, a GUI operation interface based on GPU-IOCASM was further developed, providing an integrated workflow covering grid generation, data preprocessing, model execution, and result visualization. This interface significantly lowers the barrier to using the model, improves operational convenience and efficiency, and enables users to rapidly conduct nearshore ocean dynamic simulations and result analysis.
