Dartmouth Flood Observatory

The Dartmouth Flood Observatory (DFO) is a long-running academic research project that maintains a global archive of large flood events dating back to 1985, using satellite remote sensing to detect, map, and record flooding worldwide. Originally based at Dartmouth College, it is now hosted at the University of Colorado Boulder under CIRES (Cooperative Institute for Research in Environmental Sciences). Its Global Active Archive of Large Flood Events is widely cited as a foundational reference dataset in flood research and disaster risk studies.
