Hydrologic Instrumentation Facility (HIF) Construction
The U.S. Geological Survey, in partnership with the University of Alabama, is constructing a new Hydrologic Instrumentation Facility, a science and engineering facility that will support our water observing networks and research.
MODFLOW and Related Programs
MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions. MODFLOW 6 is presently the core MODFLOW version distributed by the USGS. The previous core version, MODFLOW-2005, is actively maintained and supported as well.
Groundwater-Level Response to Earthquakes
Did you know that earthquakes can cause changes in groundwater levels? Very large earthquakes can even cause water-level fluctuations in some wells thousands of miles away, depending on the local geological conditions around the well.
Karst Aquifers
Karst terrain is created from the dissolution of soluble rocks, principally limestone and dolomite. Karst areas are characterized by distinctive landforms (like springs, caves, sinkholes) and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination.
Integrated Water Science (IWS) Basins
The U.S. Geological Survey is integrating its water science programs to better address the Nation’s greatest water resource challenges. At the heart of this effort are plans to intensively study at least 10 Integrated Water Science (IWS) basins — medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers — over the next decade. The IWS basins will represent a wide range of...
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 Availability Assessments (IWAAs)
The USGS Integrated Water Availability Assessments (IWAAs) are a multi-extent, stakeholder driven, near real-time census and prediction of water availability for both human and ecological uses at regional and national extents.
USGS Streamgaging Network
The USGS Groundwater and Streamflow Information Program supports the collection and (or) delivery of both streamflow and water-level information at approximately 8,500 sites and water-level information alone for more than 1,700 additional sites. The data are served online—most in near realtime—to meet many diverse needs.
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...
Integrated Water Availability Assessments: Upper Colorado River Basin
Integrated Water Availability Assessments examine water supply, use, and availability. Snow from the Upper Colorado River Basin contributes 92% of the natural streamflow to the entire Colorado River Basin. The UCOL IWAAs will improve our understanding of the water budget, status and trends in water quality and ecological conditions, and ecosystem response to changes in climate and human water use.
Integrated Water Availability Assessments: Delaware River Basin
Integrated Water Availability Assessments examine water supply, use, and availability. In the Delaware River Basin, which serves over 13 million people, water availability can be affected by drought, river temperature, salinity, and more. The Delaware River Basin IWAAs will investigate these and other water quantity, quality, and use issues to assess available water and how it changes over time.
