Wet antecedent soil moisture increases atmospheric river streamflow magnitudes non-linearly
Atmospheric rivers (ARs) drive most riverine floods on the United States (U.S.) West Coast. However, estimating flood risk based solely on AR intensity and duration is challenging because precipitation phase, antecedent conditions, and physical watershed characteristics (e.g., slope and soil depth) can influence the magnitude of floods. Here, we analyze how antecedent soil moisture (ASM)...
Multiyear crop residue cover mapping using narrow-band vs. broad-band shortwave infrared satellite imagery
Crop residue serves an important role in agricultural systems as high levels of fractional crop residue cover (fR) can reduce erosion, preserve soil moisture, and build soil organic carbon. However, the ability to accurately quantify fR at scale has been limited. In this study we produced annual maps of fR for farmland in Maryland, USA using WorldView-3 (WV3) imagery paired with on-farm...
Science needs for determining the effects of climate change on harmful algal blooms in the southeastern United States
The Southeastern United States has many lakes, streams, and reservoirs that serve as important drinking water sources with recreational, agricultural, and ecological uses. However, harmful algal blooms (HABs) are becoming more common in these waters, causing health issues for humans and animals. HABs have been listed as a contaminant of emerging concern, and the magnitude, frequency, and...

Mobile River Basin Study
The Mobile River Basin in Alabama, Georgia, Mississippi, and Tennessee is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound...
Integrating Remote Sensing and Numerical Modeling Technology to Detect and Manage Current and Future Harmful Algal Blooms in Louisiana’s Coastal and Tidal Waters
USGS is collaborating with partners to assess past and current CyanoHABs for the development of a predictive model and forecasting system for Lake Pontchartrain Estuary. This technology can be beneficial for informing future planning of water resource development projects, and the water management of the estuary.
A National Predictive Model for PFAS Occurrence in Groundwater
In October of 2024, USGS Scientist’s published a study where they created a model to predict PFAS occurrence in groundwater at the depths of drinking water supplies. This model can help guide our partners to sample areas where PFAS in drinking water could be an issue for the public.
