GPU-accelerated 2D shallow water equation solver for QGIS
HYDRA2DGPU performs 2D hydrodynamic flood and surface-water modelling using a CUDA finite-volume solver. It couples unstructured meshes, 1D drainage networks, hydraulic structures, and rainfall / infiltration, all inside the QGIS map canvas.
This plugin requires an NVIDIA GPU with CUDA support (compute capability >= 7.5). On first launch the plugin installs the hydra-swe2d solver backend into an isolated per-user Python environment; Windows and Linux x86_64 are supported, macOS is not.
Manual / advanced install: see https://github.com/aspragueumkc/hydra2dgpu#readme.
