Revealing nitrate uptake and dispersion dynamics using high-frequency sensors and two-dimensional modeling in a large river system
Abstract
A hydrodynamic model is applied to successfully simulate riverine nitrate dynamics High frequency data have potential to improve numerical model realism Near to the point-source, turbulent dispersion is most sensitive parameter Far from the point-source, the rate of nitrate uptake is most sensitive Numerical model simulates the diel variation in nitrate concentrations
