Research Project: Improved Understanding of Integrated Runoff, Sediment, Nutrient, and Carbon Processes in Agricultural Watersheds

Location: Water Quality and Ecology Research

Project Number: 6060-13660-008-18-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2023

Objective:
Conduct laboratory, field and modeling studies to quantify runoff, erosion, nutrient, and carbon processes in agricultural watersheds for development of improved agricultural management practices and assessments.

Approach:
This research will perform studies to evaluate runoff and landscape properties, such as soil properties, and management practices in watershed areas susceptible to sediment, nutrient and carbon transport. Field monitoring activities will be performed in conjunction with laboratory measurements to characterize and quantify sediment, nutrient and carbon yields in the study sites. Improved algorithms describing erosion, nutrient and carbon processes will be formulated for use in models for extrapolation to agricultural watershed and management plans. Modeling studies will be performed over a range of field and watershed scales using enhancements developed using the RUSLE2 and AnnAGNPS models.
