Overview of Flood Simulation

The Flood Simulation function combines a two-dimensional hydrodynamic model with 3D GIS visualization technology to achieve simulation analysis and dynamic visualization of flood processes.

  1. Simulation Based on Physical Laws
    Based on the topographic data of the specified area and following the fundamental laws of fluid mechanics, this function simulates the entire process of flood inundation, evolution, and recession. It comprehensively considers factors such as rainfall rate, surface infiltration, evaporation parameters, and hydraulic models.

  2. Three-dimensional Dynamic Visualization
    This function supports transforming abstract simulation data into vivid and intuitive dynamic visualization scenes. Users can observe the flow direction, inundation extent, and water depth changes of the flood from multiple angles and perspectives, thereby gaining an immersive understanding of disaster evolution.

  3. Click Query and Analysis
    During the simulation process, users can query and analyze specific simulation results at any location within the analysis area, such as water level, water depth, flow velocity, and other key indicators, through click operations. This provides data reference for risk assessment and emergency decision-making.

  4. Tiled Data Storage
    The result data generated by the simulation can be exported as S3M tiles. This facilitates the loading and rendering speed of massive 3D data and supports the sharing, publishing, and multi-terminal collaborative application of the results.
