Streams with a higher degree of incision may be less likely to have elevated groundwater tables, making them less effective at removing nitrogen from groundwater. By determining if there is a relationship between site characteristics and groundwater depth in the riparian corridor, riparian buffer planning can be guided to maximize efficiency. This study analyzes six sites on tributaries of the Minnesota River, characterizing them by their Rosgen stream channel type, degree of incision, soil type and dominant vegetation, and monitoring the depth to the shallow riparian groundwater table during several seasons. The monitored groundwater depth was used to confirm a water balance model of the depth to the water table at one of sites. This model was then used to predict the change to the depth of groundwater that would occur under more incised conditions.enDenitrificationIncisionNutrient removalRiparian corridorStream channelThesis or Dissertation
