Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Flood estimates are needed for the efficient design of bridges, highway embankments, levees, to protect lives and property in flood-prone areas, and to determine flood-insurance rates.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii.

Research projects intended to create regional and national data that conform to conditions predicted by general circulation models, so that land and wildlife managers can understand the likely consequences of climatic changes in their areas of study.
Review of a study monitoring changes in salinity in Alligator Bay, NC during a 1996 hurricane due to the influx of fresh and saltwater and the effect it would have on oyster aquaculture.

Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
Report prepared for the U.S. Fish and Wildlife Service with descriptions of exotic aquatic species introduced in the southeast United States with information on populations, geographic distribution, and origins.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
