Opportunity Information: Apply for L17AS00062
The grant opportunity titled "BLM-NOC, Enhancement of APEX Model for Simulating Soil Erosion and Salt Transport in the Colorado River Basin" (Funding Opportunity Number L17AS00062) is a Bureau of Land Management (BLM) cooperative agreement focused on improving the APEX model so it can better represent how sediment and salt move through landscapes and into waterways across the Colorado River Basin. APEX is described as an established, widely used model for simulating water hydrology, soils, and land management impacts, and this opportunity centers on extending its capabilities to address salinity and sediment transport issues that are especially important in the Colorado River system.
The core purpose of the project is to add new model components that allow APEX to track salts and sediments more realistically from the places they originate to where they ultimately end up, including the Colorado River itself. In practical terms, the opportunity calls for integrating a groundwater model into the existing surface water modeling framework so the model can represent the full water column rather than focusing only on surface processes. This is important because salt movement is not only a surface runoff issue; it also involves subsurface transport pathways, storage, and delayed release from groundwater systems. Alongside groundwater integration, the project includes adding chemical transport functionality so the model can simulate both dissolved salts in solution and solid forms of salt, reflecting how salinity can be mobilized, transported, deposited, and potentially re-mobilized under changing hydrologic and land management conditions.
A key emphasis in the description is understanding salinity and sediment contributions associated with BLM-managed lands. The enhanced model is intended to represent how salts and sediments are distributed and transported from these land areas within the basin, supporting a clearer basin-wide picture of sources, pathways, and downstream impacts. The notice also leaves room for incorporating additional tools as needed, signaling flexibility to use supporting models, datasets, or analytical methods that improve understanding and simulation of salinity and sediment transport throughout the Colorado River Basin.
Administratively, this is a discretionary funding opportunity under the Department of the Interior, Bureau of Land Management, categorized under Natural Resources, with CFDA number 15.236. The funding instrument is a cooperative agreement, which typically implies substantial involvement or collaboration by the federal agency during the project rather than a hands-off grant structure. Eligibility is limited to public and state-controlled institutions of higher education, indicating the work is intended to be carried out by universities or similar public academic entities with the technical capacity to modify and validate complex environmental models.
The opportunity was created on April 13, 2017, with an original closing date of April 24, 2017, reflecting a short application window. The estimated maximum award amount (award ceiling) is $1,004,036, and the posting indicates an expectation of one award, suggesting a single funded project or lead institution responsible for delivering the model enhancements and related technical outcomes.Apply for L17AS00062

Frequently Asked Questions (FAQs)
What is the title of this grant opportunity?
The opportunity is titled "BLM-NOC, Enhancement of APEX Model for Simulating Soil Erosion and Salt Transport in the Colorado River Basin."
What is the Funding Opportunity Number?
The Funding Opportunity Number is L17AS00062.
Which agency is offering this opportunity?
This is a U.S. Department of the Interior opportunity through the Bureau of Land Management (BLM).
What type of funding instrument is being used?
The funding instrument is a cooperative agreement.
What does it mean that this is a cooperative agreement?
Based on the description provided, a cooperative agreement typically indicates substantial involvement or collaboration by the federal agency during the project, rather than a hands-off grant structure.
Is this a discretionary funding opportunity?
Yes. The posting describes it as a discretionary funding opportunity under the Department of the Interior, Bureau of Land Management.
What is the program category for this opportunity?
The opportunity is categorized under Natural Resources.
What is the CFDA number listed for this opportunity?
The CFDA number is 15.236.
What is the main goal of the project?
The main goal is to improve (enhance) the APEX model so it can better represent sediment and salt movement through landscapes and into waterways across the Colorado River Basin.
What is APEX, as described in the posting?
APEX is described as an established, widely used model for simulating water hydrology, soils, and land management impacts.
Why is the Colorado River Basin specifically mentioned?
The enhancements are focused on salinity and sediment transport issues that are especially important in the Colorado River system, and the work is intended to support basin-wide understanding of sources, pathways, and downstream impacts.
What new capabilities is the project expected to add to APEX?
The notice calls for adding new model components so APEX can track salts and sediments more realistically from where they originate to where they ultimately end up, including the Colorado River itself.
Does the project involve groundwater processes?
Yes. A central element is integrating a groundwater model into the existing surface water modeling framework so the model can represent the full water column rather than focusing only on surface processes.
Why is groundwater integration important for this project?
The description states that salt movement is not only a surface runoff issue; it also involves subsurface transport pathways, storage, and delayed release from groundwater systems.
Is the project expected to model chemical transport?
Yes. The project includes adding chemical transport functionality so the model can simulate both dissolved salts in solution and solid forms of salt.
What kinds of salt behavior does the enhanced model aim to represent?
The enhanced model is intended to reflect how salinity can be mobilized, transported, deposited, and potentially re-mobilized under changing hydrologic and land management conditions.
Is sediment transport also part of the modeling enhancements?
Yes. The opportunity is explicitly focused on simulating soil erosion and sediment transport, alongside salt transport, across the Colorado River Basin.
Is there an emphasis on any specific land ownership or management areas?
Yes. A key emphasis is understanding salinity and sediment contributions associated with BLM-managed lands, and representing how salts and sediments are distributed and transported from these areas within the basin.
Is the enhanced model intended to support a basin-wide perspective?
Yes. The notice emphasizes supporting a clearer basin-wide picture of sources, pathways, and downstream impacts related to salinity and sediment.
Can additional tools, datasets, or models be used as part of the work?
Yes. The description indicates flexibility to incorporate additional tools as needed, including supporting models, datasets, or analytical methods that improve understanding and simulation of salinity and sediment transport throughout the basin.
Who is eligible to apply?
Eligibility is limited to public and state-controlled institutions of higher education.
Does the eligibility restriction suggest who the project is intended for?
Yes. The eligibility limitation indicates the work is intended to be carried out by universities or similar public academic entities with the technical capacity to modify and validate complex environmental models.
What is the maximum award amount?
The estimated maximum award amount (award ceiling) is $1,004,036.

No. The posting explicitly calls for moving beyond only surface processes by integrating groundwater to represent the full water column.
What kinds of outcomes are implied by the opportunity description?
The description implies delivery of enhanced APEX model capabilities (groundwater integration and chemical/salt transport features) to better simulate sediment and salinity transport and improve basin-wide understanding, especially related to BLM-managed lands.
