Stream denitrification plays an important role in nutrient processes. Incorrect simulation of stream denitrification could cause improper estimates of stream nitrogen loss and nitrogen transport factors, which have implications for watershed nutrient management. This paper presents an improved stream denitrification module for a watershed model to show the importance of simulation of stream denitrification, and analyzes the responses of denitrification to load reductions and flows, providing useful information for watershed nutrient management.
