Proposed removal of dams will change the characteristics of stream flow and will affect fish that swim upstream to spawn. A mathematical model of the river flow tells us where the likely problems will be located and how the flow will change.
Explains the important paleoclimatic information we have obtained from this subaqueous cavern. The time-series data show important contrasts with what would be predicted from orbital theory, provoking extensive scientific discussion.
With the South Carolina Department of Health and Environmental Control, USGS is drilling a deep geologic test well to learn about the regional Floridan aquifer, which provides groundwater to the Hilton Head area.
The Vegetation Drought Response Index is a drought monitoring and mapping tool integrating satellite observations of vegetation and climate with land cover, soil characteristics, and other environmental factors.
Map display that highlights states where the streamflow index at USGS streamgages, averaged statewide, were below normal for the past seven days with links to comparison of recent streamflow values with historic values.
