(a) Wastewater nutrient model that generates N and P discharge to surface water; (b) Soil nutrient budget model; (c) Nutrient environmental fate model, which describes the fate of N and P in the environment, including the following pathways and processes: surface N and P runoff; soil denitrification; leaching of N to groundwater; groundwater transport and denitrification; denitrification in the riparian zone (the interface between land and a stream or river); discharge to streams and rivers; N and P retention (in streams, rivers, lakes, wetlands and reservoirs).
