CURRENT EVENTS

For Flooding in Argentina, 2015, see "Current Flood Conditions" display for that area

For Flooding in Burma/Myanmar, 2015, see "Current Flood Conditions" display. Also see 2015 compared to more typical (2013) monsoon season flooding.

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.

NASA MODIS tracks intense monsoon flooding in Myanmar

(DFO event #4283, example below is Ayeyarwady Delta, Aug. 8, 2015, sediment-rich flood water is brown)

 

 

NASA MODIS Sees Flash Flooding in Southern California/Southwestern Arizona (DFO event #4279, examples below)

Left: before image, July 16. Interstate Highway I-10 is visible as thin east-west gray line crossing center.

Right: blue shows flood water in July 20 (bands 7,2,1) TERRA-MODIS display from Worldview. Bridge was destroyed and California-Arizona traffic halted.

Could MODIS and similar satellite data be routinely used to immediately detect such localized but severe flooding?

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.
