Isotopic evaluation of the National Water Model reveals missing agricultural irrigation contributions to streamflow across the western United States
The National Water Model (NWM) provides critical analyses and projections of streamflow that support water management decisions. However, the NWM performs poorly in lower-elevation rivers of the western United States (US). The accuracy of the NWM depends on the fidelity of the model inputs and the representation and calibration of model processes and water sources. To evaluate the NWM performance
Nitrogen load estimates from six nonpoint sources on Long Island, New York, from 1900 to 2019
Estimates of nitrogen loading from nonpoint sources on Long Island, New York, at or just below the land surface, are essential for assessing the current and future effects of nitrogen on the island’s drinking water and fresh and marine surface receiving waters. Annual estimates of nitrogen loading for the 120 years from 1900 to 2019 for major nonpoint nitrogen sources—septic systems, residential f
Reach-scale mapping of surface flow velocities from thermal images acquired by an uncrewed aircraft system along the Sacramento River, California, USA
An innovative payload containing a sensitive mid-wave infrared camera was flown on an uncrewed aircraft system (UAS) to acquire thermal imagery along a reach of the Sacramento River, California, USA. The imagery was used as input for an ensemble particle image velocimetry (PIV) algorithm to produce near-continuous maps of surface flow velocity along a reach approximately 1 km in length. To assess

Development of a mapper-based Long Island Sound data and research portal (Clearinghouse)
In cooperation with the Long Island Sound Study (LISS) and U.S. Environmental Protection Agency (EPA), the U.S. Geological Survey (USGS) is creating a mapper-based clearinghouse that will provide information on sources of data available throughout the Long Island Sound (LIS) watershed and allow for real-time metadata output and integration into visualization and modeling tools developed through a...
READI-Net: Providing Tools for the Early Detection and Management of Aquatic Invasive Species
The USGS has developed the Rapid environmental (e)DNA Assessment and Deployment Initiative & Network (READI-Net) to accelerate the implementation of environmental DNA (eDNA) analysis as a best practice for the early detection of aquatic biological threats. READI-Net provides tools and a strategy to collect and deliver early detection data for natural resource managers and public health protection...

Assessment of compound flood risk from the combined effects of sea level rise on storm surge, tidal and groundwater flooding, and stormwater
BACKGROUND Long Island Sound has 600 miles of coastline and there are over 23 million people living within 50 miles of its shores. In response to water-quality issues and nitrogen pollution in the Sound, Congress created the Long Island Sound Study (LISS) in 1985. LISS is a partnership of federal, state, and local government agencies, private organizations and educational institutions working tog
