CASCaDE: Computational Assessments of Scenarios of Change for the Delta Ecosystem

The Delta of the Sacramento and San Joaquin rivers provides drinking water supplies to two-thirds of Californians, and is a fragile ecosystem home to threatened and endangered species. The CASCaDE project builds on several decades of USGS science to address the goals of achieving water supply reliability and restoring the ecosystems in the Bay-Delta system.

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: 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...

National Hydrologic Model Infrastructure

The USGS National Hydrologic Model (NHM) infrastructure supports the efficient construction of local-, regional-, and national-scale hydrologic models. The NHM infrastructure consists of: 1) an underlying geospatial fabric of modeling units with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases.

Urban Waters Federal Partnership Cooperative Matching Funds Projects

The Urban Waters Federal Partnership reconnects urban communities with their waterways by improving coordination among federal agencies, particularly those communities that have been disproportionately impacted by pollution or economic distress. The UWFP draws upon Environmental Justice principles—the idea that all people, regardless of race, religion, national origin, or economic station, deserve...

National Water-Quality Assessment (NAWQA)

Our surface water, groundwater, and aquatic ecosystems are priceless resources, used by people across the Nation for drinking, irrigation, industry, and recreation. The National Water-Quality Assessment (NAWQA) Project is a leading source of scientific data and knowledge for development of science-based policies and management strategies to improve and protect our water resources.

Integration of sUAS into Hydrogeophysical Studies: Technology Demonstration and Evaluation

The USGS is evaluating the integration of small unoccupied aircraft systems – sUAS or "drones" – into USGS hydrogeophysical studies. The following projects are part of a Water Resources Mission Area demonstration and evaluation effort in collaboration with USGS Water Science Centers (WSCs) starting in June 2018.

Thermal Imaging Cameras for Studying Groundwater/Surface-Water Exchange

USGS scientists are using high-resolution handheld and airborne thermal imaging cameras in groundwater/surface-water exchange studies and other investigations where surface temperature contrasts indicate various hydrological processes. These cameras are used to quickly locate and characterize thermal (temperature) anomalies along streams, lakes, wetlands, estuaries, and across the landscape...
