Title: Improving water quality: river channel versus riparian edge
Project Type: Research
Start Date: 3/01/2010

Abstract: We propose to investigate the difference between channel and riparian denitrification rates along a rural to urban gradient on the Licking River. We hypothesize that denitrification rates (i.e., nitrogen removal) will be higher at the riparian sites due to greater organic matter content in the sediment and greater variability in soil moisture. We also hypothesize that denitrification rates will be higher in rural areas due to greater organic matter and nitrate concentrations in the surface water runoff entering the system.
