The article offers an analysis of the interactions between legal and policy science researchers within a European project on flood risk management using a "Policy Arrangement Approach" (PAA). While interdisciplinary research is increasingly becoming a 'must' in environmental governance, under what conditions is cooperation possible and desirable? Our analysis shows that the PAA is not mobilized as an interdisciplinary method, but offers a framework for researchers from different disciplines to learn to work together on a subject such as flooding, requiring interdisciplinary insights. The paper shows the steps that are progressively put in place to reach a common language and reformulate issues by benefitting from each other's view and approaches. The article concludes by drawing attention to new means of knowledge production relating to so-called "messy" or "wicked" problems, such as environmental issues. Within this framework, interdisciplinary work is not considered to be a pre-condition for the study, but rather the result of the research process itself. The analysis draws attention to the actual (working) conditions established to create an interdisciplinary community of flooding practices by challenging disciplinary borders. © 2016 Elsevier Ltd.

Simulations of cavitation processes on a grain boundary under creep conditions have been carried out, taking into account nucleation, growth, coalescence and sintering of multiple cavities. Cavity growth rates have been calculated through a resolution procedure based on the use of holomorphic complex functions. Three dimensionless parameters have been identified that are responsible for the cavitation development. Parameter studies have been carried out in order to characterise the mechanisms that are responsible for the cavitation development. These studies have been used to develop a physically motivated, simplified model in order to describe the cavitation development of the simulations in terms of global state variables. The simplified model is able to reproduce the cavitation development for all considered combinations of the dimensionless parameters and allows the description of the thickening behaviour of a cavitating grain boundary. © 2012 Elsevier B.V.
