Floods are the most prevalent type of normal disaster, affecting much more than 250 million individuals globally every single calendar year. As component of Google’s Crisis Reaction and our attempts to tackle the weather disaster, we are utilizing machine learning (ML) models for Flood Forecasting to warn people in locations that are impacted in advance of disaster strikes.
Collaboration among researchers in the field and academia is important for accelerating progress towards mutual plans in ML-relevant investigation. Certainly, Google’s existing ML-dependent flood forecasting strategy was formulated in collaboration with scientists (1, 2) at the Johannes Kepler College in Vienna, Austria, the College of Alabama, and the Hebrew University of Jerusalem, among the other folks.
These days we talk about our modern Device Studying Meets Flood Forecasting Workshop, which highlights endeavours to provide jointly researchers from Google and other universities and companies to advance our knowing of flood behavior and prediction, and construct a lot more strong answers for early detection and warning. We also explore the Caravan task, which is serving to to create an open up-supply repository for global streamflow facts, and is by itself an illustration of a collaboration that developed from the past Flood Forecasting Meets Machine Studying Workshop.
2023 Machine Understanding Satisfies Flood Forecasting Workshop
The fourth annual Google Equipment Finding out Fulfills Flood Forecasting Workshop was held in January. This 2-day virtual workshop hosted around 100 participants from 32 universities, 20 governmental and non-governmental agencies, and 11 private businesses. This forum presented an option for hydrologists, computer system scientists, and support workers to talk about worries and efforts towards improving upon world wide flood forecasts, to keep up with point out-of-the-art technologies innovations, and to combine domain expertise into ML-based forecasting strategies.
The event incorporated talks from six invited speakers, a sequence of modest-group discussion sessions centered on hydrological modeling, inundation mapping, and hazard alerting–related topics, as well as a presentation by Google on the FloodHub, which gives free of charge, community access to Google’s flood forecasts, up to 7 times in advance.

Some of the best difficulties highlighted all through the workshop have been similar to the integration of physical and hydrological science with ML to assist make have confidence in and reliability filling gaps in observations of inundated locations with products and satellite information measuring the ability and dependability of flood warning systems and increasing the interaction of flood warnings to assorted, international populations. In addition, contributors pressured that addressing these and other problems will call for collaboration in between a number of distinct businesses and scientific disciplines.
The Caravan project
A person of the key issues in conducting prosperous ML research and creating highly developed tools for flood forecasting is the need to have for substantial amounts of information for computationally pricey education and analysis. Right now, many nations and businesses gather streamflow info (typically possibly h2o stages or movement rates), but it is not standardized or held in a central repository, which will make it tricky for researchers to obtain.
During the 2019 Machine Finding out Meets Flood Forecasting Workshop, a group of scientists determined the need to have for an open up source, world wide streamflow information repository, and designed suggestions close to leveraging free computational methods from Google Earth Motor to tackle the flood forecasting community’s problem of facts assortment and accessibility. Adhering to two years of collaborative get the job done among researchers from Google, the school of Geography at the College of Exeter, the Institute for Equipment Studying at Johannes Kepler University, and the Institute for Atmospheric and Local climate Science at ETH Zurich, the Caravan venture was designed.
In “Caravan – A world community dataset for big-sample hydrology”, revealed in Nature Scientific Facts, we explain the undertaking in far more detail. Primarily based on a international dataset for the growth and teaching of hydrological styles (see figure under), Caravan offers open up-source Python scripts that leverage important weather and geographical info that was previously made general public on Google Earth Engine to match streamflow facts that users upload to the repository. This repository originally contained knowledge from much more than 13,000 watersheds in Central Europe, Brazil, Chile, Australia, the United States, Canada, and Mexico. It has further benefited from group contributions from the Geological Survey of Denmark and Greenland that consists of streamflow info from most of the watersheds in Denmark. The purpose is to go on to develop and increase this repository to enable researchers to entry most of the world’s streamflow knowledge.

The route forward
Google programs to go on to host these workshops to help broaden and deepen collaboration concerning field and academia in the advancement of environmental AI products. We are searching forward to looking at what innovations may come out of the most modern workshop.
