Multi-hazard early warning platform. Open to any model. Built to turn simulation science into lives saved.
Open EWS is the operational layer between your physical models (hydraulic, hydrological or atmospheric models,...) and the people they protect — automated pipelines, AI, ML surrogates for sub-second prediction, and standards-based dissemination out of the box.
A defined, automated, AI-assisted pipeline — from raw rainfall to people protected. Your physical model stays the source of truth; the ML surrogate makes it operational; the alert layer makes it useful.
Any engine. Upload .inp, .prj, .cas — or plug an API. Auto-detect, validate, and prepare.
Same topology, 500× faster. A world model that lets planners run thousands of alternative futures.
Cell broadcast, CAP/XML, SMS, IoT sirens — auditable, multi-channel, standards-based.
Alerts, telemetry and ML confidence — Integrating available components that power national agencies, utilities and basin authorities.
Open EWS doesn't compete with existing models — it becomes the operational layer that turns them into deployable early warning systems.
First fully operational vertical. EPA SWMM, HEC-HMS, HEC-RAS, TETIS, Iber, TELEMAC, and ANUGA 1D/2D coupled simulation with real-time meteorology.
Fire spread modeling, fuel moisture sensors, and evacuation alert integration.
Wind field modeling, structural risk assessment, and storm track nowcasting.
Tidal coupling, wave overtopping models, and coastal flood forecasting.
Extensible architecture ready for any hazard with a simulation model behind it.
Open EWS scales horizontally across geography and vertically across the lifetime of a hazard event.
Streets, neighborhoods, single-stream watersheds, individual treatment plants.
Multi-municipality regions, river basin authorities, county-level civil protection.
National agencies coordinating across all basins, regions and verticals.
Long-range probabilistic signals, ML precursors, scenario warm-up days ahead.
Deterministic + ensemble forecasts, alert pre-staging, audience targeting.
Real-time observed data, surrogate-driven response, multi-channel dissemination.
Open EWS integrates the full chain — from model to alert. Five modules, one operational platform.
14+ simulation engines ready to use. Standardized JSON-lines protocol — bring your own engine too.
AEMET, NOAA, IoT gauges, and weather APIs. IDF curves and frequency analysis built in.
1D, 2D, and coupled 1D+2D modes. Batch runs for scenario analysis and automated calibration.
GNN surrogate models for instant prediction. TimesFM nowcasting. Train, deploy, and benchmark from the platform.
ES-ALERT / EU-ALERT cell broadcast, SMS, email, push notifications, IoT sirens, and CAP/XML interoperability.
Open EWS adapts to your scale and operational needs — from single-river pilots to multi-hazard national deployments.
Agencies deploying multi-hazard early warning at scale, with auditability and standards compliance.
Managing flood risk, dam safety, and hydrological monitoring networks across watersheds.
Integrating EWS into SCADA and operational workflows — urban drainage, dams, generation.
Leveraging Open EWS as a deployment platform — ship faster, with a defensible methodology.
Catastrophe modeling, parametric triggers and exposure analytics — live hazard footprints feeding pricing and claims pipelines.
Groups developing and validating new models, ML approaches, and hazard methodologies.
Deploy in days, not quarters. Bring your simulation engine, your sensors, your audience — we provide the operational backbone.
