Emerging Flood Inundation Mapping Technologies
The following technologies represent state-of-the-art tools, methodologies, and techniques that the USGS and our partners are researching and testing. Most of these techniques are experimental and not publicly available, but could significantly improve our ability to plan for and respond to flooding events in the future.
2011 - The Year of the Flood
2011 proved to be another record-breaking flood year in the United States. USGS Water Science Center personnel from North Dakota to Louisiana measured springtime floods on the Red River of the North, the Ohio River, the Mississippi River, and many tributaries. The Missouri River and its tributaries saw record-breaking snow-melt runoff through the summer, followed closely by Hurricane Irene and...
Urban Waters Federal Partnership—Bronx and Harlem River Watersheds (New York, N.Y.)
The Harlem and Bronx Rivers provide ecological and social resources in an intensively urban area. Connecting people to rivers requires clean water—the USGS is helping to assess the efficacy of green infrastructure to improve the quality of stormwater that flows into the rivers.
National Water-Quality Project Sampling Methods
USGS National Water Quality Assessment (NAWQA) studies require analyses of stream and bed-sediment samples for major ions, nutrients, sediments, and organic contaminants that are consistent across time and space. Procedures have been designed specifically to produce...
Regional SPARROW Model Assessments of Streams and Rivers
Regional SPARROW Model Assessments of Streams and Rivers (archived) includes models (and supporting data) that were developed for seven large regions of the conterminous United States. Results from the models can be used to compare nutrient sources and watersheds that contribute elevated nutrient loads to...
Handheld Thermal Imaging Cameras for Groundwater/Surface-Water Interaction Studies
USGS scientists are using high-resolution handheld thermal imaging cameras in groundwater/surface-water interaction studies and other investigations. These cameras are used to quickly locate and characterize thermal anomalies in streams, lakes, and adjacent structures. Variations in temperature can be used to track the heat carried by flowing water, such groundwater discharge into a stream....
What does groundwater have to do with ice in Alaska?
USGS scientists are working alongside university researchers in Alaska to understand how groundwater and permafrost conditions change over time due to seasonal variations and climate change. Changes in permafrost can pose a threat to built infrastructure (like roads, homes, and pipelines) and to valued ecological resources that provide important habitats for wildlife.
Fiber-Optic Distributed Temperature Sensing Technology Demonstration and Evaluation Project
Fiber-optic distributed temperature sensing (FO-DTS) is an emerging technology that has promise for characterizing estuary-aquifer and stream-aquifer interaction and for identifying transmissive fractures in bedrock boreholes.
Borehole Nuclear Magnetic Resonance (NMR)
Borehole nuclear magnetic resonance (NMR) is an emerging geophysical method being applied to hydrogeology investigations.
Spectral Gamma Borehole Logging
Spectral gamma borehole geophysical methods measure natural-gamma energy spectra, which are caused by the decay of uranium, thorium, potassium-40, and anthropogenic radioactive isotopes. Spectral gamma data can be used to identify and quantify the amount of uranium, thorium, and potassium-40 isotopes detected in boreholes.
Geophysics for USGS Groundwater/Surface Water Interaction Studies
Understanding the interaction of groundwater and surface water is essential to water managers and hydrologists for the development of effective water-resource policy, protection, and management. The USGS conducts applied research to evaluate the use of new or emerging hydrogeophysical tools and methods to improve our understanding of groundwater/surface-water exchange.
State Contacts for Water-Use Data
Water-use data is compiled for each of the United States as well as for the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. The list below contains a link to the USGS water-use site for each entity, if one exists, as well as the point of contact for State-level information.
