Satellite Flood Measurement
Ohio State University researchers have found a way to use satellites that measure sea level to also measure flooding over land. Because the data cannot be processed quickly enough, the information cannot be used to forecast a flood, but it can help scientists better understand how floods happen.
“After a flood, we can look back at the satellite data to pinpoint when the flood began and find out how far the flood waters extended, which is really important for flood modeling,” said C. K. Shum, a professor of earth sciences at Ohio State.
