Abstract
    An overview of the state‐of‐the‐art of water quality modelling for water quality management is presented. There are different types of models: data driven black box models, empirical/conceptual models and physically‐based models. Models are needed to represent the sewer‐waterwater‐river‐catchment system. Also sediment transport is a very important but complex part of water quality modelling. We can observe a variety in complexity, also within the DSS systems. For example, at the catchment domain the generation of water quality components can be as simple as imposing a concentration at the outlet (e.g EMC) as in WaterCAST to a more complex process based approach as in LASCAM. Inriver water quality processes are also modelled with different degrees of complexity, from the extended Streeter and Phelps equation in StreamPlan to a multi‐level of complexity as in AQUATOOL.

    At present, most applied models are physically based, but the integration of complex physically based models in integrated systems may become too complex. There is hence a need for simplified models that can easily be integrated in an integrated water quality model system.
