A hydrodynamic model computes the transport coefficients for the water quality model, which contains all relevant state variables and all relevant physical, chemical and biological processes, including nutrient cycles and primary production by two types of algae. The model performs a dynamic simulation of the water quality. The model has been calibrated and is being applied for the computation of waste reduction scenarios.
