Click on map for tabular information and access to inundation maps, 2007-present

An Excel xml version of tabular data for all events, 1985-present, is also available

GIS data, for all events, 1985-present are available (1,2,3,4,)

 

Flood-generating Watersheds (under development)

Provided by River Watch , and special processing of NASA/Japanese Space Agency AMSR-E data through a collaborative effort between the Joint Research Centre, Ispra, Italy (GDACS project) and Dartmouth College.

 

Current 7-day Wet and Dry Runoff Anomalies, based on AMSR-E River Discharge Measurements (under development)

Provided by River Watch , special processing of NASA/Japanese Space Agency AMSR-E data, and our global watershed database. Yellow watersheds: runoff < 90% mean for this seven day period. Red watersheds: runoff > 160% for this seven day period.

 

We use orbital remote sensing to detect, measure, and map river discharge and river flooding, world-wide. Observatory activities include:

• River Watch, a satellite-based flood measurement and hazard mapping system (example).

• Flood and Drought Monitor: regional views of changing surface water (example).

• World Atlas of Flooded Lands, a global compilation of all floods mapped.

• Active Archive of Major Floods, 1985 to present (also see current floods, above).

• Rapid Response Inundation Maps, produced and published while floods are underway. Recent examples are:

• Flooding south of Veracruz, Mexico, October 1, 2008
• Flooding in the Uttar Pradesh Region of India 1, September 28,2008
• Flooding in the Uttar Pradesh Region of India 2, September 28, 2008
• Flooding in the Kailali District of Nepal, September 28, 2008
• Flooding Along the Rio Grande and the Conchos Rivers in Texas and Mexico, September 22,2008
• Flooding along the Rio Grande, September 22, 2008
• Flooding along the Rio Grande, September 22, 2008
• Flooding on the Mahanadi River in Orissa, India, September 20
• Flooding on the Mahanadi River in Orissa, India, September 20, 2008

  DFO and this web site facilitates maximum practical use of the satellite-based information for disaster relief, risk assessment, and water resources research and monitoring. Your inputs and support are invited.
