Flood Archive Atlas

World Atlas of Large Flood Events 1985-2002

The information presented in this atlas is derived from a wide variety of news, governmental, instrumental, and remote sensing source. It is designed in order to better understand the evolution of extreme flood events since 1985. The archive is "active" because it is currently updated (with current and past events). For additional information concerning how these maps and tables are created, please review the Archive Notes.

Because this database combines different information source and cover 18 years, it can not be totally consistent. This question of data consistency is recursive with this kind of database. Usually this question of consistency is avoided or quickly presented. The originality of this project is to acknowledge the data inconsistency, to make the user aware of the reliability of the data. This concept is part of a research project.

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.
