Communicating on floods: propositions for using an interactive educational small-scale model

Abstract

We designed a small-scale schematic catchment model for a science exhibition open to all, for disseminating knowledge about flood generation, defining notions like vulnerability and hazard, and for observing the results and the limits of structural mitigation measures. This successful experience may be fitted for communicating on real-life development projects, provided it is adapted to the client's objectives and the audience's expectations. However, such a catchment model is not an accurate and comprehensive scale model and can only reproduce qualitative properties of streamflows. Keeping that in mind, we further investigate three potential uses: supporting discussion within a small group, helping communicating on an on-going study, and displaying features of a detailed project.
