Open Source Hydraulics & River Systems tools

Open-source 2D shallow-water modelling in Python from Geoscience Australia — strong for dam break and tsunami.

GPU reimplementation of the CaMa-Flood global river routing model — continental flood simulation on PyTorch/Triton.

Deltares' open flexible-mesh suite for rivers, estuaries and coasts — hydrodynamics to morphology.

Jupyter notebook suite for batch HEC-RAS and HEC-HMS runs — parallel execution and calibration statistics.

The Bristol raster flood model behind global flood maps — open source with GPU-accelerated solvers.

Python automation for HEC-RAS 6.x: batch runs, parallel execution and HDF results extraction.

Deltares' reduced-complexity compound flood model — coastal, fluvial and pluvial drivers in one fast solver.

EDF's open-source finite-element suite for free-surface flow — 2D/3D rivers, estuaries, waves and sediment.

Python control and post-processing for 2D hydraulic models — SRH-2D and HEC-RAS 2D results to VTK and beyond.

Read HEC-RAS HDF5 geometry and results into GeoPandas/xarray — built for FEMA's flood-risk data pipelines.
