What’s available on the USGS DRAGON Web site?
DRAGON includes information on 15 deltas of international importance: the
Amazon,
Chao Phraya,
Danube,
Ganges,
Huang He,
Irrawaddy,
Lena,
Mekong,
Mississippi,
Nile,
Okavango,
Rhine,
Selenga,
Volga, and
Yangtze.
The site includes a description and several maps of each river and
delta, an interactive Google map viewer highlighting the 15 deltas, and useful Web links
related to delta research, universities, government agencies, and non-governmental organizations
working in delta environments, sources for spatial or water data, and USGS resources available
to all.
The
Proceedings page provides presentations and abstracts from the 2009 DRAGON Asia Summit held in Siem Reap, Cambodia, as well as the 2007 International Delta
Roundtable held in Lafayette, Louisiana, USA. A 10-minute
podcast of key parts of the
2007 conference is also provided at the top of the page.
The DRAGON Web site also provides useful tools such as a
searchable digital library related
to delta science. The
comparison maps tool allows the user to choose two deltas for
comparison through side-by-side maps of cyclone risk, elevation, flood risk, irrigated land,
land cover, population density, protected land, RAMSAR wetlands, and reservoir volume.
