Abstract

An integrated approach for immission based discharge and nutrient modeling of catchments with multiple urban areas, agricultural and natural areas is proposed. A hydrological model with detailed soil moisture processes is applied for the rural catchment parts to reproduce the runoff pathways involved. Nutrient concentrations are assigned based on land use and soil type. Urban areas (including CSO structures, tanks and WWTPs) are modelled by means of a pollution load model. The approach is applied to a catchment in Hesse, Germany. It is possible to reproduce processes within and interactions between the different sub-systems as well as processes in the receiving water body. Further model improvements could be deduced by means of the case study that was carried out and will be implemented in next versions of the model approach.
