Google Flood Hub issues 7-day river-flood forecasts in ungauged basins

A Nature paper on 20 March 2024 described Google’s operational AI hydrology system that provides free 7-day flood forecasts, including in ungauged watersheds, via Flood Hub covering dozens of countries.

Operational global flood forecast access is major (tier 3). Attribution shared with public hydro data. Peer-reviewed skill plus live service. Realization is deployed forecasts. Medium durability as models update.

What happened

The model, related to the NeuralHydrology line, was compared with Copernicus GloFAS and deployed without paywall. Google later stated coverage on the order of 100+ countries and large exposed populations. Forecasts support alerts but do not by themselves prove lives saved in a controlled study.
