Using Inverse Modeling and Dual Isotopes (δ¹⁵N and δ¹⁸O of NO₃) to Determine Sources of Nitrogen Export From a Complex Land Use Catchment

Abstract

Anthropogenic disturbance of the nitrogen (N) cycle through nitrogen loading from urbanization, industrialization, and agriculture often leads to the eutrophication of downstream receiving water environments (Eyre, 2000;
