Delta Research And Global Observation Network (DRAGON)

Overview of DRAGON

The U.S. Geological Survey (USGS) National Wetlands Research Center (NWRC) has initiated an effort to improve management outcomes for massive deltaic coastal systems like that of the Mississippi River Delta by comparing the ecological, hydrological, geological, and biogeochemical processes of large deltaic systems across the globe. The Delta Research And Global Observation Network (DRAGON) is developing a science framework for comparing, integrating, and ultimately predicting the effects of key drivers and management practices in these large ecosystems. The DRAGON brings together scientists and managers to model the large river deltas around the world.

Comparing North America's largest major river and delta, the Mississippi, with similar systems requires partnerships with scientists and managers from other continents. Following Hurricane Katrina, coastal resource managers have proposed a radical new approach to managing the Mississippi River levee, floodplain, navigation, and other key components of the delta. In light of this approach, there is an urgent need for better scientific information that connects to engineering and coastal restoration enterprises. The first DRAGON roundtable meeting was hosted by the USGS National Wetlands Research Center in the fall of 2007. Most recently the DRAGON Asia Summit was held in Siem Reap, Cambodia, in June 2009.

The DRAGON partnership is creating an international community of practice to share data on the great deltas and rivers of the world and to develop comparative models and visualization tools in order to facilitate ecological forecasting regarding climate change and development that ultimately helps in guiding decision making.
