Abstract

The invention provides a nested interaction method and device for spatial geographic data and a groundwater numerical model, which can facilitate the rapid processing and operation of the groundwater numerical model for regional complex problems. The method includes: step 1. preparing a regional spatial geographic data file; step 2. performing horizontal finite difference numerical dispersion according to the regional scope; step 3. performing a connection calculation between the vector spatial geographic data and the shapefile file representing the finite difference grid; step 4 .Extract the spatial data information saved in the finite difference grid and organize it into the type required for the groundwater model; Step 5. Extract the grid file information and organize it into the type required for the groundwater model; Step 6. Analyze the time-varying boundary conditions Read and sort to generate the boundary time-varying data type required by the numerical simulation model; Step 7. According to the requirements of the groundwater numerical simulation model for the input file, generate the array file representing the spatial information obtained above into the model input file.
