Global Active Archive of Large Flood Events

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

Each entry in the table and related "area affected" map outline represents a discrete flood event. However, repeat flooding in some regions is a complex phenomenon; we strive for 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.

The Archive includes: 1) an online .html table of recent events, only; 2) Excel .xls and .xml files for all events, 1985-present, updated as the recent events html is updated; 3) a GIS (Mapinfo format) file set (1 2 3 4 5) providing flood catalog numbers and area affected outlines, only, and updated as the recent events html is updated;, and 4) a GIS (.shp format) file set (1 2 3 4) providing catalog numbers and area affected map outlines, with much of the tabular attribute data (e.g., dates, duration, fatalities) also included. The GIS .shp file is updated infrequently, and its file name provides the date of last update.

Many floods have now been imaged by satellite and translated by Dartmouth Flood Observatory staff into individual maps of inundation extents. To view these maps, follow any hyperlinks in the Archive .html, .xls, or .xml files in the "Country" column for a specific event. Many other floods have been imaged and mapped but are instead shown as "mapped flooding" lands in the Global Flood Atlas/Surface Water Record.
