Opportunity Summary:

This grant opportunity, titled "Evaluation of Transverse Feature Design Options" (Funding Opportunity Number R12SS40039), is a Bureau of Reclamation (Upper Colorado Region) discretionary funding announcement offered as a cooperative agreement. The overall goal is to continue an existing collaboration to strengthen real-world design guidance for river engineers and other field practitioners who plan, design, and evaluate transverse river training and habitat features. In practical terms, the project is aimed at improving the design guidelines, analytical equations, and modeling tools used to predict how different transverse structures will influence river hydraulics, sediment behavior, infrastructure protection, and habitat outcomes.

A major portion of the work focuses on documenting and interpreting an ongoing physical model study. This documentation is not just a summary of results; it is meant to translate the findings into technically defensible guidance that can be used by practitioners. Specifically, the physical model effort compares the behavior of bendway weirs modeled in a native channel geometry (as referenced in the announcement) against other transverse structures that had been studied previously, including spur dikes and vanes. The intent is to understand how differences in structure type and placement within realistic channel forms affect flow patterns, scour and deposition, channel stability, and related performance measures.

Alongside the physical modeling documentation, the opportunity calls for the development of a three-dimensional hydraulic model of transverse features. This 3D numerical model is expected to be created, calibrated, and validated using previously collected data from the physical scale models. Calibration and validation are emphasized because the modeling tool is meant to be reliable enough to support deeper evaluation of critical design options, beyond what can be tested physically in every scenario. A validated 3D model can help explore a wider range of flow conditions, geometries, and design configurations, helping practitioners make better-informed decisions about structure dimensions, spacing, orientation, and anticipated maintenance needs.

The announcement also includes a related technical objective tied to river sediment processes: performing a critical review of the many hypotheses that have been proposed to explain sediment plug formation, identifying which mechanisms are most viable, and improving understanding of the underlying mechanics. This component is framed as directly relevant to managing river conditions on the Middle Rio Grande, with the aim of maximizing environmental benefits while reducing risks to river maintenance and operations. Better understanding of sediment plug formation could inform how and when transverse features are used, how flows are managed, and what operational constraints might reduce undesirable sedimentation impacts.

The expected outcome is improved, field-ready design guidance and updated equations that better predict how transverse features perform, including clearer insight into the level of infrastructure protection they provide and the fish habitat they can create. In other words, the project is intended to move from research and modeling toward practical products that make designs more consistent, defensible, and effective when implemented in real rivers.

Administratively, the opportunity anticipated a single award with a total funding amount of $266,154 (award ceiling and floor both listed as $266,154) and no cost-sharing or matching requirement. The CFDA program referenced is 15.517 (Fish and Wildlife Coordination Act). The original closing date was September 13, 2012, later extended to September 21, 2012, and the opportunity was archived on September 22, 2012. Eligible applicants were broadly defined and included state and local governments, nonprofit organizations, public and private institutions and organizations, federally recognized tribal governments, individuals, small businesses, for-profit organizations, and Native American organizations. A Bureau of Reclamation contact was provided for access issues: Timothy Wagoner, Grants Management Specialist, at 801-524-3704.
