Title: Evaluation of saturated buffers as a conservation drainage practice for treating agricultural subsurface drainage
Location: Roland, Dysart, Ellsworth, Colo and Slater
Time Period: 2018-2020
Research Team: Chris R. Rehmann, Michael A. Perez, Cassandra J. Rutherford, Thomas M. Isenhart, Dan B. Jaynes, Andrea R. McEachran and Loulou C. Dickey
Project Description: This study involves the use of MODFLOW and analytical modeling to gain a better understanding of how saturated riparian buffers function, in terms of groundwater flow and nitrate transport and removal. Suggestions for improving the design of saturated riparian buffers in terms of nitrate removal will be made based on the findings from the models.
