Data Quality

Each entry in the table and related "area affected" map outline represents a discrete flood event. However, repeated flooding in some regions is a complex phenomenon and may require a compromise between aggregating and dividing such events. The listing is comprehensive and global in scope. Deaths and damage estimates for tropical storms are totals from all causes, but tropical storms without significant river flooding are not included. Supplemental Information

The information presented in the Dartmouth Flood Observatory Archive is derived from news, governmental, instrumental, and remote sensing sources. The archive is ""active"" because current events are added immediately.
