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.
