Freshwater withdrawals and population in Alabama, 1960-2005
September 28, 2016

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined...

Hurricane Potential in the United States and Puerto Rico

Hurricanes bring destructive winds, storm surge, torrential rain, flooding, and tornadoes. A single storm can wreak havoc on coastal and inland communities and on natural areas over thousands of square miles. In 2005, Hurricanes Katrina, Rita, and Wilma demonstrated the devastation that hurricanes can inflict and the importance of hurricane hazards research and preparedness.

This thin line of residue is an indicator of how high the waters reached, yet the fragile nature of these marks means they must be...

Chris Henry and Daniel McCay, USGS hydrologic technicians, use GPS equipment to survey a high-water mark outside of a flooded elementary school in Denham Springs, Louisiana, August 28. This school was located in one of the hardest hit flood areas and the blue line simulates how high the water was at its peak during this historic flood.

Daniel McCay and Chris Henry, USGS hydrologic technicians, use a level to draw a line on a high-water mark August 26. In most circumstances, when a high-water mark is flagged it would then be surveyed with GPS equipment to obtain its exact coordinates and elevation. However, because of the possibility of more storms hitting Louisiana the teams were initially only flagging marks at first, in order...

A new USGS-NASA study found widespread shoreline loss along heavily oiled areas of Louisiana's coast after the 2010 BP Deepwater Horizon oil spill and compared the erosion from the spill with coastal changes Hurricane Isaac caused in 2012.

The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding. Click here to learn more about the work the USGS has completed for Hurricane Matthew.
