Grid based 2-Dimensional land surface flood model (G2D) is a squared grid-based 2D surface flood model developed by the Korea Institute of Civil Engineering and Building Technology (KICT). The development history of the G2D model is as follows.
- The G2D model was first developed in 2017.
- In 2018, simulation speed and stability were improved.
- In 2019, GUI was developed as QGIS plug-in.
- In 2020, the G2D model written by C++ was developed.
- In 2021, the simulator using NVIDIA GPU was developed.
The G2D model is being continuously developed by the KICT.
- Tthe G2D GUI for QGIS plug-in (QG2D).

- The G2D v.2021 and later have been developed using the CUDA tool kit 11.2 or later environment.
- CUDA 11 needs NVIDIA Driver version 452.39 or later (RTX Desktop Manager and CUDA Toolkit are not required).
- Even if NVIDIA Graphic card is not installed and 'UsingGPU' option is not applied, cudart64_110.dll file is required. cudart64_110.dll file has to be in the folder included in the Windows path or in the same folder of G2D.exe.
- VCOMP140.DLL is required in the folder included in the Windows path. The details are as follows.
- If the OS is Windows 11, there is no problem.
- If the OS is Windows 10, VCOMP140.DLL file can be installed by using one of the methods below.
- Install Visual Studio 2015 or later version including VCOMP140.DLL file.
- Install Microsoft Visual C++ 2015 Redistributable or later version including VCOMP140.DLL file.
- Install NVIDIA driver 536.67 or later version including VCOMP140.DLL file by default(installing RTX Desktop Manager is required) settings.
- Install QGIS 3.10.14 or later version including VCOMP140.DLL file and add "C:\Program Files\QGIS 3.10\bin" to Windows path. The directory name of QGIS can be changed according to the QGIS version.
