Minimize risk with proven performance

HydroForecast swept a yearlong, short-term flow forecasting competition.

In every competition region, HydroForecast was more accurate further into the future and provided better insight in both drought conditions and 1,000-year storms.

Leverage AI to manage water-related risks

As climate change and extreme weather impact our water system, relationships between the variables that affect flows, like snowpack and temperature, are changing.

In these challenging circumstances, stakeholders from across the industry need new tools to improve subseasonal-to-seasonal water supply predictions.

Learn how to leverage AI, across industries and use cases, to manage water related risks with industry leading accuracy.

"HydroForecast has proven to be an important datapoint for Brookfield Renewable's reservoir planning and management activities. It has led to a more proactive approach to the short- and mid-term planning, an improved probabilistic view of generation and enhanced trading and operational decision-making. HydroForecast has been a truly successful project for Brookfield Renewable."

A novel approach with science-guided AI

HydroForecast learns to represent hydrologic processes by identifying relationships between satellite observations, basin characteristics, meteorological forecasts, and streamflow measurements.

We believe that the best model is one grounded in physical scientific principles, and enhanced by finding deep connections in the relationships between data using machine learning models.

Our work is based on peer-reviewed research, and is the result of collaboration with leading universities and researchers.

Historical Reanalysis

HydroForecast can construct a 20-year daily continuous streamflow record at any location in the world, partially gauged, or completely ungauged, and in both natural and altered watersheds.

Virtual gauge

Increase the density of a streamflow monitoring network by adding points where having up to date weather, snow and streamflow data is important for real-time decisions.
