Erosion along the Rio Puerco during the flood of 2006 following herbicide application to control saltcedar in 2003.
December 3, 2016

Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

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...

USGS streamgage with Satellite antenna at the edge of river.
September 24, 2016

The USGS in Michigan-in cooperation with local, State, Tribal, and Federal partners-operates 155 streamgages recording stage and streamflow, and 13 lake-level gages. There are about 7,400 streamgages nationwide; many of these gages provide real-time data in 15-minute increments, which typically are transmitted to the World Wide Web every 1 to 2 hours using satellite, telephone, or cellular...

Data on low-flow characteristics are used by water-resources managers for a variety of purposes, including water-supply planning, making decisions about wastewater-discharge and water withdrawal permits, and evaluating in-stream flow requirements. The Michigan low-flow network currently consists of seven sites where streamflow is typically measured only during low-flow periods. In addition to...

USGS Water-Quality equipment with cover opened at edge of river near a footbridge.
September 24, 2016

The USGS operates a network of real-time water-quality monitoring stations that measure up to five physical parameters. The parameters are temperature, specific conductance, pH, dissolved oxygen, and turbidity. One to four of those parameters are measured at 26 sites, while all five parameters are measured at 13 sites. These data are used for decision making about hydroelectric power...

Crest-Stage Streamgage equipment set up at edge of a stream.

Historically, small streams with drainage areas less than 100 square miles have not been adequately represented in regional peak- (high) flow analysis. In Michigan, USGS operates 24 traditional crest-stage gages, where stage and streamflow is only measured during high flows, and 6 continuous-record crest-stage gages, where cooperators can continually monitor stage and USGS maintains a high-...

Tracer-based characterization of hyporheic exchange and benthic biolayers in streams

Shallow benthic biolayers at the top of the streambed are believed to be places of enhanced biogeochemical turnover within the hyporheic zone. They can be investigated by reactive stream tracer tests with tracer recordings in the streambed and in the stream channel. Common in-stream measurements of such reactive tracers cannot localize where the...

Potentially exploitable supercritical geothermal resources in the ductile crust

The hypothesis that the brittle–ductile transition (BDT) drastically reduces permeability implies that potentially exploitable geothermal resources (permeability >10−16 m2) consisting of supercritical water could occur only in rocks with unusually high transition temperatures such as basalt. However, tensile fracturing is possible even in...

Local geology controlled the feasibility of vitrifying Iron Age buildings

During European prehistory, hilltop enclosures made from polydisperse particle-and-block stone walling were exposed to temperatures sufficient to partially melt the constituent stonework, leading to the preservation of glassy walls called ‘vitrified forts’. During vitrification, the granular wall rocks partially melt, sinter viscously and densify...
