Sediment-Water Nitrogen Fluxes in a Backwater System of the Upper Mississippi River

摘要

This research quantifies nitrogen (N) fluxes and transformations at the sediment water interface in relation to N loading and uptake for a backwater system of the Upper Mississippi River. Goals of this work were to provide a better understanding of the roles that backwater sediments play in uptake and removal of N for purposes of determining the management potential of increasing hydrological connectivity between large rivers and adjacent backwaters, wetlands, and the flood plain to enhance overall N removal efficiency.
