"...the lack of planned accommodation to the river's high sediment load and its super-elevation above the surrounding terrain set the stage for exceptionally dangerous levee failures and channel avulsions." Read about the Great Flood of 2010 in Pakistan

There are two map series accessible from the above global index: "Current Flood Conditions", providing daily, satellite-based updates of surface water extent, and the "Global Atlas of Floodplains", a remote sensing record of floods, 1993 to 2015. Links to GIS data supporting the displays are also provided. This >20 year long effort has been sustained by grants and contracts from NASA, the European Commission, the World Bank, the Latin American Development Bank and others to Dartmouth College and to the University of Colorado.

The Flood Observatory facilitates practical use of space-based information for international flood detection, flood response, future risk assessment, and hydrological research. In 2013-2017, it is leading a NASA SMD/ESD Applied Sciences Program project to improve World Food Programme use of flood mapping information. Click on video below for visualization of WFP logistics. Also see this video for information about the role of the International Charter for Space and Major Disasters in making satellite data available for disaster response.
