Modeling nitrate in tile-drained watersheds of east-central Illinois
Reservoirs in east-central Illinois are subject to nitrate contamination due to the agricultural nature of their watersheds. Field tile systems provide direct links between leached nitrate and surface drainage systems. The purpose of this study was to develop a model for predicting flow and nitrate loading in a surface drainage ditch at the outlet of a tile-drained watershed. In particular, relationships were developed for the upper portion of the Little Vermilion River Watershed in Champaign County, Illinois. The Root Zone Water Quality Model (RZWQM) was used as a tool in model development.
