When wildfires scorch a landscape, the flames are just the beginning. NASA is helping communities across the nation foresee and prepare for what can follow: mudslides, flash flooding, and contaminated surface water supplies. A new online tool called HydroFlame, built with support from NASA’s Earth Science Division, relies on satellite data, hydrologic modeling, and artificial intelligence to predict how wildfires could affect water resources, from tap water to the rivers and streams where people fish.
