Philadelphia communities along the Schuylkill River and Darby Creek now have new tools to help inform residents of impending flooding. The U.S. Geological Survey recently installed three new streamgages in Manayunk, Eastwick, and downtown near 30th St., which will monitor water levels, and provide vital data used by emergency managers and flood forecasters to help…

A USGS analysis of New Jersey water quality trends found levels of total nitrogen and total phosphorus, which fuel algae blooms, declined or stayed the same at most stream sites between the 1970s and 2011. At all sites studied, chlorides from road salt increased over that time.

A better understanding of sediment and freshwater flow into Galveston Bay is now available from a new U.S. Geological Survey report, done in cooperation with the Texas Water Development Board, and the Galveston Bay Estuary Program.

Extensive groundwater withdrawals have caused the loss of land-surface elevation, or subsidence, in parts of the Houston-Galveston region in Texas, according to a recent U.S. Geological Survey annual report.

River diversions are a common coastal wetland restoration tool, but recent research, conducted by U.S. Geological Survey in collaboration with researchers in Louisiana State University’s Department of Civil and Environmental Engineering and the LSU AgCenter, has shown that large-scale Mississippi River diversions may significantly change water quality in estuaries, affecting economically important shellfish and fish…

Traffic modeling has been of interest to mathematicians since the 1950s. Research in the area has only grown as road traffic control presents an ever-increasing problem. Generally, models for traffic flow in road networks are time-dependent and continuous, that is, they describe traffic by a continuum rather than as individual drivers or cars. These macroscopic models…

Changes in rainfall and temperature are predicted to transform wetlands in the Gulf of Mexico and around the world within the century, a new study from the USGS and the University of Texas Rio Grande Valley concludes.Sea-level rise isn’t the only aspect of climate change expected to affect coastal wetlands: changes in rainfall and temperature…

If coastal salt marshes are like savings accounts, with sediment as the principal, all eight Atlantic and Pacific coast salt marshes studied are "in the red," researchers found.Scientists working on a rapid assessment technique for determining which US coastal salt marshes are most imperiled by erosion were surprised to find that all eight of the Atlantic and Pacific Coast…

A new research article, with lead authors from the University of Gothenburg, gives indications of the best places in Iceland to build thermal power stations.In Iceland, heat is extracted for use in power plants directly from the ground in volcanic areas. Constructing a geothermal power station near a volcano can be beneficial, since Earth’s mantle…

A 145,000 sq km area of peatland swamp forest has been discovered in the Congo Basin, writes Tim Radford, and it holds a record 30 Gt of carbon, equivalent to 20 years of US fossil fuel emissions. Now the race is on to protect it from damaging development that would emit that carbon over coming…
