Opportunity Information: Apply for W81EWF 25 SOI 0011

This grant opportunity supports a focused field and analysis project in the Rocky Mountains aimed at improving how scientists measure and model snow and soil water after wildfires. The core idea is to use a mobile cosmic ray neutron sensor to repeatedly survey snow water equivalent (SWE) and soil moisture along transects that cross both burned and unburned terrain. By collecting comparable measurements through different stages of the water year, the project is intended to reveal how wildfire impacts the seasonal buildup and melt of snowpack, how soil wetness evolves over time, and how those changes vary with elevation.

The work is structured around a set of specific deliverables. The recipient is expected to conduct five to six mobile sensor survey campaigns and deliver processed SWE and soil moisture datasets from each campaign. These repeat surveys should intentionally span a range of conditions (for example, early season accumulation, peak snowpack, and melt-out periods) so the resulting dataset captures the full seasonal cycle in both burned and unburned areas. Alongside data delivery, the project requires comparative analysis of annual (water year) patterns, with the explicit goal of identifying differences in SWE and soil moisture processes attributable to burn status and elevation gradients.

A major applied outcome of the project is to improve future hydrologic and snowmelt modeling in wildfire-impacted watersheds. The opportunity calls for analysis that helps partition snowmelt into two key pathways: infiltration into the soil versus direct runoff. This partitioning is critical in post-fire settings because burn severity and soil surface changes can shift how much meltwater soaks in versus runs off quickly, affecting flood risk, water supply timing, and downstream ecosystem impacts. The expectation is that findings from the mobile sensor measurements and seasonal comparisons will directly inform model calibration and parameterization, meaning the project should translate observations into modeling-relevant insights rather than stopping at descriptive statistics.

The award is issued as a cooperative agreement under a science and technology/research and development category, indicating active collaboration expectations with the sponsoring agency. It is offered by the U.S. Army Engineer Research and Development Center under CFDA 12.630. The funding opportunity number is W81EWF 25 SOI 0011, with an anticipated single award up to an award ceiling of $248,000. The original closing date listed is 2025-08-25.

Reporting and data stewardship are also central requirements. The recipient must quality control the collected field data, analyze it, and document the methods and results in formal technical reports or peer-reviewed journal manuscripts. Eligibility is restricted to non-federal partners of the Rocky Mountains Cooperative Ecosystems Studies Unit (CESU), so only organizations that qualify under that CESU partnership framework can apply.
