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.<p>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. ","AbstractOtherLang":"Het rapport geeft een overzicht van waterkwaliteitsmodellen en hun gebruik in beslissingsondersteunende systemen (BOS). Er zijn verschillende soorten modellen in gebruik: fysiche modellen, conceptuele modellen, empirische modellen en datadriven modellen.<p>Samengevat kan er gesteld worden dat er verschillende graden van complexiteit gebruikt worden, ook binnen BOS. Rivierbekkenmodellen kunnen zeer sterk vereenvoudigd zijn, van een constante concentratie in de rivier (e.g. EMC) tot een complex procesgebaseerde modellering zoals in LACSAM. Bij de rivierwaterkwaliteitsprocessen zien we ook verschillende niveau's van complexiteit, van een 'Streeter-Phelps' vergelijking in StreamPlan tot een multi-niveau complexe modellering zoals in AQUATOOL.<p>Veel toepassingen van waterkwaliteitsmodelleringsmodellen maken gebruik van complexe modellen, maar de integratie van deze modellen is moeilijk en doorgaans niet gebruiksvriendelijk. Om die reden is er een nood aan eenvoudige modellen die gemakkelijk geïntegreerd kunnen worden binnen beslissingsondersteunende systemen.
