Next Generation Water Observing System (NGWOS)
Substantial advances in water science, together with emerging breakthroughs in technical and computational capabilities, have led the USGS to develop a Next Generation Water Observing System (NGWOS). The USGS NGWOS will provide real-time data on water quantity and quality in more affordable and rapid ways than previously possible, and in more locations.
Integrated Water Prediction (IWP)
The USGS Integrated Water Prediction science program focuses on the development of advanced models for forecasting multiple water quality and quantity attributes including water budgets and components of the water cycle; water use; temperature; dissolved and suspended water constituents, and ecological conditions. It is also developing the cyberinfrastructure and workflows required to implement...
Next Generation Water Observing System: Illinois River Basin
The Next Generation Water Observing System provides high-fidelity, real-time data on water quantity, quality, and use to support modern water prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The Illinois River Basin provides an opportunity to implement the NGWOS in a system challenged by an...
Next Generation Water Observing System: Upper Colorado River Basin
The Next Generation Water Observing System (NGWOS) provides high-fidelity, real-time data on water quantity, quality, and use to support modern prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The headwaters of the Colorado and Gunnison River Basins provide an opportunity to implement NGWOS in a...
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System (NGWOS) provides high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin was the first NGWOS basin, providing an opportunity to implement the program in a nationally important, complex interstate...
Sampling Methods for the Water Quality of San Francisco Bay Project
The Water Quality of San Francisco Bay Research and Monitoring Project measures changes in water quality along the deep channel of the San Francisco Bay-Delta system using submersible sensors and discrete water samples. Learn more about how we collect and measure water-quality data.
Research Vessel David H. Peterson
The Research Vessel David H. Peterson begain service with the U.S. Geological Survey in 2015. Named after a founder of the Water Quality of San Francisco Bay Research and Monitoring Project, this vessel is a high-tech scientific platform for estuarine research. Learn more about how the R/V David H. Peterson makes our research possible.
Hydrologic Instrumentation Facility (HIF)
The USGS Hydrologic Instrumentation Facility (HIF) supports the water-resource monitoring efforts of USGS scientists and other Federal scientists by providing quality-assured hydrologic equipment and instrumentation support.
Water Quality of San Francisco Bay Research and Monitoring Project
Since 1969, the U.S. Geological Survey has maintained a research project in the San Francisco Bay-Delta system to measure and understand how estuarine systems and tidal river deltas function and change in response to hydro-climatic variability and human activities.
Transboundary Assessments of Water Quality in the Pacific Northwest
In 2019, the USGS began studying the baseline water-quality of selected transboundary rivers in the Pacific Northwest. These studies are designed to characterize current water-quality conditions so as to facilitate future assessments of potential impacts related to upstream mining activities.
U.S. National Committee for the International Hydrological Programme
The Intergovernmental (formerly International) Hydrological Programme (IHP) is the United Nations Educational, Scientific and Cultural Organization's (UNESCO) international scientific cooperative program in water research, water resources management, education, and capacity building.
