Advanced Capabilities and Research

The U.S. Geological Survey's National Water-Use Science Project (formerly the National Water-Use Information Program) is responsible for compiling and disseminating the nation's water-use data. Established by USGS in 1978, the USGS National Water-Use Science Project built on the legacy of the Estimated Use of Water in the United States report series, begun in 1950 and produced every 5 years.

Patent for a pore-water profiler and method for sampling pore water. The pore-water profiler includes a sample intake probe that receives the fluid to be sampled. (Full details provided by the U.S. Patent and Trademark Office website.)

Patent for a sequential, time-integrated collector having an electronic controller that actuates either of two electrically-actuated valves, each connected to a water reservoir. (Full details provided by the U.S. Patent and Trademark Office website.)

A method of quantitatively determining surface area of a sample uses polyvinylpyrrolidone (PVP) dispersed in a solution containing the sample, and determining the amount of PVP that has deposited on the sample. (Full details provided by the U.S. Patent and Trademark Office website.)

A self-contained, transportable system for conducting any of hydrologic tests or water sampling techniques without the need for retooling or readjusting the system. (Full details provided by the U.S. Patent and Trademark Office website.)

A method is provided for the manufacture of mineral power crystals having a uniform mean size. The method includes forming a solution which is highly supersaturated with respect to the crystals. (Full details provided by the U.S. Patent and Trademark Office website.)

In the operation of the present invention, a compacted porous medium is provided with a supply of the desired liquid and is subjected to centrifugal force until the measurement of the flow rate of liquid through the medium is substantially constant. (Full details provided by the U.S. Patent and Trademark Office website.)

The principles essential to the interpretation of gamma, gamma-spectrometry, gamma-gamma, and various types of neutron logs include the nature of subatomic particles and the particles and photons emitted by unstable isotopes.

As one of several Focus Area Studies within the USGS National Water Census (NWC), the USGS has completed a 3-year study of water availability and use in the Colorado River Basin.

Stream, river, and lake bed sediment are reservoirs for many contaminants. These contaminants include some “legacy” contaminants, like DDT, PCBs, and chlordane, and chemicals currently in use, like the insecticide bifenthrin and many flame retardants. Learn about techniques used to study sediment-associated contaminants and their importance to aquatic biota.

When planning for a flood, there are three key questions that must be answered: What areas will be flooded? How deep will the flood waters get? When will the flood arrive? Historical flooding can help a community anticipate how much impact similar flood events could have, but there are other methods and tools that can provide more accurate and nuanced estimations of a wide variety of flood...

Floods are the leading cause of natural-disaster losses in the U.S. More than 75 percent of declared Federal disasters are related to floods, and annual flood losses average almost $8 billion with over 90 fatalities per year. Although the amount of fatalities has declined due to improved early warning systems, economic losses continue to rise with increased urbanization in flood-hazard areas.
