Validation¶
Hydrata runs the same ANUGA solver developed by Geoscience Australia and the Australian National University, through the same simulation pipeline. Every simulation on Hydrata produces directly comparable results to running ANUGA locally on the same inputs.
Validation Record¶
ANUGA has been validated against:
- 30+ benchmark problems: laboratory flume experiments, field observations, analytical solutions
- Peer-reviewed publications: over 100 papers using ANUGA for flood, tsunami, and storm surge modeling
- Government-grade applications: used by Geoscience Australia for national tsunami risk assessments
Benchmarks¶
| Benchmark | Description | Status |
|---|---|---|
| Merewether | Urban flood in Newcastle, NSW, validated against observed flood marks | Verified on Hydrata |
| ANUGA validation suite | 30+ standard benchmarks from the ANUGA repository | Passes (upstream CI) |
Regulatory Acceptance¶
ANUGA is accepted by regulators in multiple jurisdictions. See Regulatory Acceptance for details by jurisdiction.
How Hydrata Preserves Solver Integrity¶
- Same ANUGA solver: Hydrata runs the open-source ANUGA solver through the same simulation pipeline, with
anuga_coreas a dependency. - Reproducible execution: the same inputs produce directly comparable outputs on Hydrata cloud or local Python.
- Portable model files: Hydrata's
scenario.jsonformat can be exported and run locally withrun_anuga. - Open-source toolchain:
run_anuga(MIT licence) handles the Hydrata-to-ANUGA translation. View on GitHub.
