Over the course of the twentieth century, hydraulic engineering has come to rely primarily on the use of computational models. Disco and van den Ende hint towards the reasons for widespread adoption of computational models by pointing out that such models fulfill a crucial role as management tools in Dutch water management, and meet a more general desire to quantify water-related phenomena. The successful application of computational models implies blackboxing : “[w]hen a machine runs efficiently … one need focus only (...) on its inputs and outputs and not on its internal complexity. Thus, paradoxically, the more science and technology succeed, the more opaque and obscure they become”.. (shrink)

Translation abstractSummary: Risks in the Making: The Mediating Role of Models in Water Management and Civil Engineering in the Netherlands. Reliance on models can make technological cultures susceptible to risks through the assumptions, uncertainties, and blind spots that may accompany modeling practices. Historian of science Peter Galison has described computer modeling practices as “trading zones”, conceptual spaces in which a shared language is hammered out in an attempt to facilitate collaboration between different social groups, such as engineers and policymakers. Although (...) such a shared language may enable collaboration between diverse groups, it may also make the relation between modeling practices and knowledge of risks less visible, since the shared language does not necessarily acknowledge how models produce knowledge about their world. In that respect, models have a ‘mediating’ role, since they are not straightforward representations of the world, but involve a process of translating phenomena into formalized representations that enable experimentation. Drawing on insights from Science and Technology Studies (STS) and empirical work in the domains of hydrology, hydrodynamics, geotechnical engineering, and ecology, this paper emphasizes the importance of understanding the mediating role of models in shaping the understanding that various actors hold with regard to water‐related risks. Failing to appreciate the mediating role of models hampers the ability of actors to understand the assumptions, uncertainties, and blind spots that accompany simulation practices, and may put technological cultures at risk.
