In this study, riparian groundwater nutrient concentrations were evaluated near an incised stream under 4 perennial land cover types common to southern Iowa with the objectives to assess how groundwater quality differed by 1) distance away from an incised stream and 2) perennial land cover type. Results indicate that channel incision lowers water tables in the near-stream zone and maintains more aerobic conditions but did not result in enhanced nitrogen mineralization or leaching to groundwater. It is suggested that nutrient losses from perennial buffers in the region do not greatly impact regional water N and P loads although average concentrations in riparian groundwater may exceed proposed stream nutrient criteria
