The Dartmouth Flood Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR in 2010. Its sustained, not-for-profit operation depends on grant and project support. Financial contributions may be tax-deductible.
Since late 1999, satellite data have been obtained by the Flood Observatory, processed to detect water/land boundaries, and analyzed to produce flood inundation limits in vector GIS format. DFO's Current Conditions updates this information each day into displays showing current surface water compared to the record of flooding. In 2017, we are revising the displays for global coverage. New format sample: 090E030N.
DFO's River and Reservoir Watch provides experimental, fully automated satellite-based river discharge and reservoir area measurements. They are updated daily. Ground-based gauging stations can accurately observe flow changes along rivers and streams (blue line in example below, Site #91, Wabash River, central USA). Using specially processed microwave information (in black), satellite data can provide similar data at very much lower cost and across international boundaries. DFO is developing an array of validated measurement sites for the Earth (click on link above or map below).
Twice-daily updates at 2:30 and 14:30 Local Denver Time
West Virginia and Virginia, USA, June 3, 2018. Red is flooding imaged by Copernicus Sentinel 1 SAR data provided by the European Space Agency; June 3 image is compared to a matching May 10, 2018 image. This is a portion of the Shenandoah River southwest of Front Royal, Virginia; flooding is predicted to increase during next several days.
The Flood Observatory facilitates use of space-based information for
international flood detection,
flood response, future risk assessment, and hydrological research. In 2013-2017, it led a NASA Applied Sciences project to assist World Food Program use of flood mapping information. Click on video below for visualization of WFP logistics.
This work is made possible by data acquired by NASA,
the Japanese Space Agency, and the European Space Agency, and funding support from NASA and the European Commission,
through the Global Disaster Alert and Coordination System (GDACS) project, Joint Research Centre, Ispra, Italy. The Observatory was founded in 1993 at Dartmouth College, Hanover, NH USA and moved to the University of Colorado, INSTAAR, CSDMS in 2010. The institutional support of both universities is gratefully acknowledged.
