About Open EWS
Open EWS is a multi-hazard platform for Early Warning Systems. It transforms simulation models — regardless of engine or hazard type — into deployable, real-time early warning services. With support for 14 simulation engines, a cloud model repository, automatic calibration, ML surrogates, and probabilistic nowcasting, it gives civil protection teams actionable forecasts.
What it does
Model Integration
Connects 14 simulation engines — from EPA SWMM and HEC-RAS to TELEMAC and ANUGA — under a single operational layer.
Cloud Simulation
Runs deterministic and coupled 1D+2D simulations in the cloud with live results streaming and batch scenario execution.
ML Surrogates
GNN-based surrogate models deliver instant predictions (<10 ms) — 635x faster than physics solvers — for real-time decision support.
Probabilistic Nowcasting
Ingests rainfall observations and TimesFM-based probabilistic nowcasts (p10/p50/p90) to drive flood-risk forecasts.
Auto-Calibration
Automated parameter calibration with observed data, multi-objective optimization, and parallel batch runs.
Alert Dissemination
Threshold-based 4-level alerts via ES-ALERT/EU-ALERT cell broadcast, SMS, email, push, IoT sirens, and CAP/XML.
Who we are
Open EWS is built and maintained by a team of specialists in risk modeling, decision support systems, machine learning, and artificial intelligence. Based in Spain, the team combines deep expertise in hydraulic engineering, real-time data systems, and operational early warning to deliver a platform that bridges the gap between simulation models and civil protection operations.
