You cannot model everything

Models are not replicas of reality; they merely represent certain aspects of reality. Houses in miniature parks may seem realistic models of real houses, but insight you will not find toilets you can flush. Accordingly, the model to be used in a specific river restoration project depends on the specific questions that need to be answered: Which measures are considered? Which effects are important for stakeholders? What is the required level of detail? There is not a single best model for all situations. Moreover, the modelling of certain effects or details may be constrained by limits to computation time and computational power, or even be impossible because of insufficient knowledge. Using models for river restoration thus requires careful selection on a case-by-case basis.
