Request for Proposals Application Materials Budget Justification Template "Covered UAS" Assessment Guide The Water Resources Research Act (WRRA) Program supports an annual National Competitive (104)g) Grant program in cooperation between the US Geological Survey and the Water Resources Research Institutes and Centers. The Kentucky Water Research Institute (KWRI) coordinates applications from universities or colleges in Kentucky.

An objective of the 104G program is to promote collaboration between the USGS and university scientists in research on significant national and regional water-resources issues. Proposals exhibiting substantial collaboration between the USGS and the applicant are strongly encouraged. Collaborative proposals should describe in detail the respective roles of the USGS and the applicant in the proposed work.

Funding for this program typically requires a 1:1 match over a three-year period. Competitive applications are typically divided by topic. The USGS has indicated that for FY2026 they anticipate releasing two RFPs on two topics: PFAS and a yet to be determined topic.

The anticipated release date is mid-April with a due date in mid-May. If you are considering an application for these grants, Please contact kwri@uky. edu to begin coordination on the application.

Responsibility for the administration of the Water Resources Research Act Program has been delegated to the U.S. Geological Survey (USGS). The 54 Institutes are organized as the National Institutes for Water Resources (NIWR). NIWR cooperates with the USGS in the administration of the Water Resources Research Act Program.

Priority 1: Economic value of Information of the USGS streamgage network and associated National Water Information System (NWIS). Applicants should review the National Hydrologic Warning Council 2006 report for a listing of benefits categories. For this proposal, USGS is most interested in categories (1) through (3) in the 2006 report; categories (4) and (5) are of significant but lesser interest.

USGS appreciates that proposals may seek a tradeoff between examining multiple benefit categories at a reduced geographic scale versus a limited number of benefit categories at a national scale. While preference will be given to those proposals that provide a Nationwide assessment, please consider the minimum geographic scope to be Hydrologic Unit Code 12 (Hydrologic Unit Maps | U.S. Geological Survey).

Priority 2: Model Advancement and Machine Learning Integration Explore methods to develop new hydrologic models in large, regional areas or, where possible, at the national level to enhance understanding of water availability. Provide information on promising modeling approaches to inform science questions specific to a region.

Examples include: Machine Learning Techniques for Water Quality Data: Apply AI and machine learning methods to harmonize water quality data across different sources, improving integration and accessibility for hydrologic modeling.

Groundwater and Base Flow Predictions : Specifically apply machine learning techniques to predict transient groundwater levels or base flow to streams, enhancing the understanding of these critical hydrologic processes. Causal Machine Learning Exploration: Investigate the use of causal machine learning to evaluate current or ongoing studies impacted by non-causal modeling.

This approach should help quantify the extent of the problem associated with non-causal machine learning modeling and inform the development of more robust, process-based modeling frameworks.

Aquatic Invasive Species Competitive Grants - $1,387,000 funding available, maximum award $346,875 The challenges and opportunities that link aquatic invasive species and water resources are poorly understood, despite the real and growing effect of numerous aquatic invasive species on water quality, water quantity, and aquatic ecosystems.

Research is needed to better identify and understand these interactions and to guide management decisions that will help to improve invasive species management and thus reduce effects of invasive species on water resources and aquatic ecosystems at local, regional, and national scales.

Proposals are sought on the following specific areas of inquiry (levels of priority are not assigned, and the order of listing does not indicate the level of priority): Effects: Research that improves our understanding of the effects of aquatic invasive species on lakes, rivers, and associated tributaries in the upper Mississippi River basin, including changes to water quantity, water quality, and ecosystem dynamics.

Characteristics: Research that identifies physical, biological, and chemical characteristics of water bodies that infer resistance and resilience to the distribution, establishment, and effects of aquatic invasive species in the upper Mississippi River basin.

Research is needed to better understand these interactions to guide management decisions that will improve invasive species management and result in positive effects on aquatic ecosystems. Management: Research on assessment of the detection, spread, and management of aquatic invasive species in the upper Mississippi River basin and the connections to human dimensions, both socially and economically.

Note that this does not include physical control of AIS. Per-and polyflouroalkyl Substances (PFAS) Competitive Grants - $2,775,000 funding available, maximum award $309,000 Water Resources Research Institutes [or Centers] have been established in each of the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam.

The 54 Institutes are organized as the National Institutes for Water Resources (NIWR). NIWR cooperates with the USGS in the administration of the Water Resources Research Act Program.

The challenges and opportunities of understanding the effects of per-and polyfluoroalkyl (PFAS) substances on water resources are poorly understood, despite the real and growing effect of this group of man-made substances on water quality and the resultant exposure to humans, other organisms, and ecosystems.

Research is needed to better understand these interactions and guide management decisions that will improve water resources at the regional or national scale.

Proposals are sought on the following specific areas of inquiry (levels of priority are not assigned, and the order of listing does not indicate the level of priority): Media-specific methods: Enhanced methods for detection on specific media, with a clear indication of new or different compounds, new or different methodological approaches, lower detection levels for specific media or compounds, especially with respect to EPA health guidelines for PFOA (Perfluorooctanoic Acid) and PFOS (Perfluorooctane Sulfonate).

Media of interest include (in ranked order): (1) Tissues/plasma, (2) sediment, (3) air or interfaces, (4) water. Atmospheric sources: Improved understanding of atmospheric exchange in PFAS distribution and fate. This may include methods to determine transport of PFAS to the atmosphere and to subsequent receiving waters, such as a water method that determines "new" compounds based on their likelihood to occur in the atmosphere.

Processes oriented at the molecular level, physical or biological: Process-oriented research of PFAS fate, transport, and effects, with emphasis on molecular-level understanding of PFAS precursor transformation, sorption dynamics, or process-oriented research of mechanisms of PFAS bioaccumulation and(or) biological/ecological effects, or biodegradation of PFAS along source to receptor pathways and identification of mitigation methods and engage modeling and forecasting processes for prediction, prevention, and mitigation of environmental risk of exposure to PFAS in ecosystems and human population.
