Application of D-SEM to a catchment in Central Amazonia: Calibration and validation of the carbon and nitrogen cycles
We applied the D-SEM model for predicting carbon (C) and nitrogen (N) dynamics in a natural forest ecosystem in a Central Amazonian microcatchment. A continuous collection of hydrological and water quality data (2002-2010) was used for model calibration and validation. Comparisons between predicted...
