Hydrogeology and Flooding on the Web

Flooding

U.S. Geological Survey, Water Resources Publications and Data
Historical stream flow and real-time streamflow condition data are available by state. Daily (or more frequent) river stage, date, and time are given, and plotted as graphs over a period of several days.

Federal Emergency Management Agency (FEMA)
This site offers a wide variety of useful flood-related information. There is information on flood mitigation for those who live in flood-prone areas, with things to do before, during, and after a flood.

It contains background information on the destructive power of floods and flashfloods, including an animation of a car floating in only two feet of water, information on changing views of floodplain management, the National Flood Insurance Program (NFIP) and the National Flood Insurance Reform Act.

The site includes a map of special flood hazard areas in the U.S., and information on how to obtain FEMA flood insurance rate maps, including the latest digital Q3 flood maps.

Photo archives include pictures of the Midwest floods of 1993 and Louisiana floods of 1995, among other disasters.

The National Dam Safety page contains information on some of the notable dam failure disasters in the 1970's that led to increased dam inspection. There is also a search function, as well as information on earthquakes, hurricanes, tornados, winter storms, and fires, and the Oklahoma City bombing. You can even see quicktime movies of Christmas trees burning.


Midwest Floods 1993

Great Floods of 1993
This site discusses factors leading to the floods in Iowa and surrounding states, with regional flood images taken by NASA aircraft, local flood images from ground and air, and climatologic data including graphical precipitation records from 1895 to 1993, a temperature map by state of the US for July 1993, and soil wetness as depicted by satellite imagery.

NASA flood images

Regional image before flood, from Minnesota to Missouri

Regional image during flood, from Minnesota to Missouri

Pre-flood images from September 24, 1992

Peak flood images from August 1, 1993, three days after the flood crest

The images include a brief description, a Mississippi River channel image, and an enlargement of the river channel area.


Army Corps of Engineers 1993 Flood Data
This site has the 1993 flood impact report, maps of flood extent, damage, etc.

The Great Flood of Summer 1993: Mississippi River Discharge Studied
http://www.agu.org/sci_soc/walker.html
This is a paper from Earth in Space Vol. 7, No. 3, November 1994, pp.11-14. 1994 American Geophysical Union, documenting the causes of the Midwest flooding, with a graph of Mississippi River discharge, satellite imagery, and consequences of the flood in the Gulf of Mexico.

General information about the flood from the team assembled by President Clinton, including data, maps (shaded topographic relief, levee database, available water capacity, hydric soils, surface water ponding, wetlands, and precipitation), and images.

Floods
http://www.eastnc.coastalnet.com/weather/nwsmhx/flds.htm
This site from the National Weather Service in Newport, North Carolina provides background information and statistics on flashfloods and floods, as well as flood safety rules. There is information on stream gauging (including a map of stream gauges across the U. S.) and flood forcasting. Information is provided on National Oceanic and Atmospheric Administration (NOAA) Weather Radio (with a listing of cities and the radio frequencies) and the National Weather Service

National Inventory of Dams
http://corps_geo1.usace.army.mil/hq.html
This site contains a database on more than 75,000 dams throughout the US and its territories, which is a complete copy of the 1995-96 revised National Inventory of Dams CD-ROM available from the Army Corps of Engineers. You can download a 6 minute Powerpoint(tm) slide show with color pictures.

HazardNet
http://hoshi.cic.sfu.ca/~hazard/
This site, at Simon Fraser University in Vancouver, Canada is a demonstratieon project of the International Decade for Natural Disaster Reduction with data, maps, and images. A section on floods is under development.


Weather-related sites

National Weather Service
http://www.nws.noaa.gov/
This site provides information on current weather, historical climate data, and information on weather-related topics, including U.S. coastal tide tables for selected cities.

World Meteorological organization
http://www.nws.noaa.gov/oso/wmo.shtml
http://www.wmo.ch/web/ddbs/ddbs.html
(in Geneva, Switzerland)
This is a specialized agency of the United Nations that exists in part to facilitate worldwide cooperation in establishing networks of stations for meteorological and hydrological observations, and to promote the rapid exchange of meteorological and water related information. The Geneva site contains links to meteorological and hydroligical sites around the world.


Hydrology

National Operational Hydrologic Remote Sensing Center
http://www.nohrsc.nws.gov/
This center operates under the Office of Hydrology of the National Weather Service, creates and distributes a variety of products that use remotely sensed data, including national and regional snow cover maps daily during snow season, and maps of mean daily surface air temperature. A flood map for Des Moines, Iowa is also included.
