This Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $499,696 to the Stroud Water Research Center Inc. to conduct collaborative research on nitrogen pollution removal processes in riparian soils and wetlands. Specifically, the award will fund an innovative study from July 2022 to June 2025 to identify the key soil conditions that regulate the balance between dissimilatory nitrate reduction to ammonium (DNRA) and...
This National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant award of $399,984 to the University of Wisconsin-River Falls (UW-River Falls) seeks to study the cycling and transport of carbon (C) and nitrogen (N) in agricultural soils. The two-year project, titled "EMBRACE-EAR-GROWTH: Coupling In-Situ Probing and Modeling Moisture-Related Soil Carbon and Nitrogen Cycling and Transport", aims to: Decipher redox-related soil C and N cycling, mobilization,...
This $576,061 federal Project Grant awarded by the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) supports the development of an integrated crop-vadose zone-groundwater model to enhance understanding of nitrate transport and transformation in agricultural areas. Led by the University of Nebraska-Lincoln, the project involves integrating crop models for corn, soybean, and potato into a new simulation model capable of depicting soil...
This $300,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to enhance the resilience of groundwater resources in major U.S. agricultural regions through a participatory planning approach. The project team at Southern Illinois University, with sub-awards to Iowa State University and the University of Nebraska, will develop an AI-based modeling system to empower farming communities in addressing groundwater depletion and...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports research by Boise State University to investigate how microbial activity and fluid flow dynamics in river sediments influence the production and emission of the potent greenhouse gas nitrous oxide. The $189,234 award will fund experiments and numerical simulations to determine the spatial and temporal patterns of low-oxygen microzones that facilitate nitrous oxide generation. This work aims...
This $300,236 National Science Foundation project grant will fund collaborative research exploring the influence of agricultural tile drainage on streamflow and water temperatures in the Midwestern United States. Funded under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences to strengthen the national scientific enterprise, this research will develop quantile regression models to examine how tile drainage alters streamflow and water...
This $396,079 Project Grant awarded by the National Science Foundation (NSF) Geosciences program (CFDA 47.050) aims to investigate how bacteria and biofilm growth in river sediments regulate the formation of low-oxygen microzones that produce the potent greenhouse gas nitrous oxide. The University of California, Davis (UC Davis) will perform sediment column experiments, microfluidic studies, and numerical simulations to characterize the spatio-temporal dynamics of these anoxic microzones and...
This $2,646,047 federal Project Grant award from the National Science Foundation's (NSF) Computer and Information Science and Engineering (CISE) program (CFDA 47.070) is developing a national integrated watershed evaluation framework to improve water resource management. The framework will bring together diverse hydrologic datasets and provide tools for advanced model evaluation and exploration of watershed conditions. The project, led by Princeton University, will engage a diverse community...
This National Science Foundation Project Grant award of $856,624 provides funding from January 2023 through December 2025 to support research entitled "Continental-Scale Determinants of Stream Solute Spatial and Temporal Patterns." The award is made under the Geosciences program (CFDA 47.050) to support basic research in the atmospheric, earth, and ocean sciences. Specifically, the University of Florida will leverage a continental-scale dataset across the eastern United States to...
This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $303,703 to develop a novel approach for characterizing hydrostratigraphy using water level data collected from multi-level monitoring wells. The University of Iowa will collect water level measurements every 10 seconds from 10 to 15 depths in monitoring wells located at a contaminated groundwater site. Analyzing the response of water levels to rainfall and pumping changes will help delineate the...
