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...

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...

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...

National Aquifer Code Reference List

This list of national principal aquifer codes and names are fixed values assigned by the National Water Information System (NWIS). Aquifers are identified by a geohydrologic unit code - a three-digit number related to the age of the formation, followed by a 4 or 5 character abbreviation for the geologic unit or aquifer name.
