Google Research's Yossi Matias says their flood model learns from the places that have data and then predicts for the places that don't:
"We published a paper in Nature with what we call Global Hydrologic Model."
"And really what we showed is that we can actually build models that are learning from flood events in places that we have enough data, and then apply it also to places that we don't have as much data."
"And what started as an impossible problem, quote unquote, we actually now not only showed that we can drive the science, but also the same team, we've built a system that now provides up to seven days prediction in 150 countries covering 2 billion people."
"So it's already life-saving because it's out there, it's available for responders, for governments through what we call a flood hub."
"And you know, just a few months ago, we had the government of Nigeria and organizations called GiveDirectly actually use an API to our flood hub to actually send money to villagers so they can evacuate ahead of time."
He is a Google executive describing Google's own system, and the seven-day, 150-country, 2-billion-person figures are the company's.
The hard part is that the rivers which flood most destructively are often the least instrumented, so a forecast is needed exactly where there is no local record to build one from. And a prediction only counts when something acts on it: here that was an API call moving cash to households before the water arrived, not a dashboard someone had to notice.
