# Hydrata

> Hydraulic-model verification, delivered two ways: verify your own model on the
> platform (self-serve), or have Hydrata verify it for you (done-for-you advisory).
> Designed by engineers, for engineers. Open source. Auditable.

Hydrata is a hydraulic-model verification platform for consulting engineers,
local authorities, dam owners, and researchers. Verification is delivered in
two modes:

**Mode A: Verify it yourself (self-serve platform)**
Upload a finished HEC-RAS .zip or ANUGA project. The platform runs automated
verification checks (mass balance, mesh quality, parameter sensitivity,
jurisdiction-checklist comparison) and returns results through a live web portal
with full audit trail. You can also run ANUGA 2D flood simulations in the cloud.
API and MCP access available for power users.

**Mode B: Have Hydrata verify it (done-for-you advisory)**
Send us your model. A Hydrata analyst runs the verification engagement and
delivers a signed verification (chartered-engineer sign-off, CPEng Engineers
Australia) in a live review portal for geospatial reviewer comments.
Independent third-party review. Five working days, end to end.

In both modes, Hydrata is not the engineer-of-record. The client's engineer
remains responsible for the design. Hydrata identifies issues and documents
the verification process.

The platform organises its work around four claims, in order:

- Validate: does the model match observed reality? (calibration, sensitivity, benchmark comparisons)
- Verify: is the model internally consistent? (mass balance, mesh quality, boundary conditions, parameter audit)
- Comply: does the submission meet regulator requirements? (jurisdiction-specific templates, signed deliverables, audit trail)
- Communicate: can a non-modeller understand the result? (interactive maps, scenario comparison, public stakeholder views)

Target users: consulting engineers responsible for flood, stormwater, or coastal
model submissions; municipal stormwater teams; owner's engineers and project
managers reviewing third-party deliverables; researchers using ANUGA.

Supported engines today: HEC-RAS 2D (.zip / RAS Mapper exports) and ANUGA (native).
Additional engine ingests added on request.

Built on GeoNode 5.x, Django 5, and GeoServer 2.27.x. The full pipeline
(ingest, audit, report generation, results portal) is open source and
auditable. Australian company (NSW, Australia).

## What Hydrata Verifies

- Mass balance and continuity for HEC-RAS 2D and ANUGA runs
- Mesh quality: triangle skew, cell-size transitions, boundary alignment
- Parameter sensitivity on critical inputs: Manning's n, rainfall depth, boundary stage
- Jurisdiction-checklist comparison against the consultant's design criteria
- Audit trail: every input, run, and reviewer comment recorded and exportable
