1a.Objectives (from AD-416):
Conduct laboratory, field and modeling studies to quantify erosion processes by concentrated flows in agricultural watersheds for development of improved erosion control practices and assessments.
1b.Approach (from AD-416):
This research will perform studies to evaluate runoff and landscape properties, such as topographic profiles, soil properties, and management practices in watershed areas susceptible to ephemeral and edge-of-field gully erosion formation. Field monitoring activities will be performed in conjunction with laboratory measurements to characterize and quantify headcut migration, gully growth, and sediment yield in the study sites. Improved algorithms describing gully erosion processes will be formulated for use in models for extrapolation to different watershed and management conditions. Modeling studies will be performed over a range of field and watershed scales using enhancements developed within the AnnAGNPS model.
This agreement was recently started and no progress has been made that can be stated yet this FY.
