Nitrogen Accountability for Fertile Streams
Publication: Journal of Environmental Engineering
Volume 111, Issue 4
Abstract
The Stream Nitrogen and Oxygen Analysis Program (SNOAP) is a one‐dimensional, pseudo unsteady state, water quality model, which simultaneously solves both nitrogen and dissolved oxygen mass balance equations. The SNOAP model was successfully calibrated and verified for three, independent, data intensive water quality surveys. The modeled stream system was unsteady due to significant upstream impact from wastewater treatment plant effluent discharges. Denitrification was found to be the dominant total nitrogen sink. Average denitrification rates calculated by the SNOAP model range from The computed values compare quite favorably with measured laboratory sediment denitrification rates which ranged from In addition, the rate of ammonia‐N decay was found to be the most accurate nitrogen species estimator of in‐stream nitrification rates.
