Flood risk management can be defined as a complex ensemble of practices, knowledge and regulations tools that aims to improve the protection and/or the functioning of floodable areas, before, during and after the realisation of risk. Consequently, different and numerous types of stakeholders or actors develop particular practices and their own perceptions of how the risk should be managed. In this perspective, numerous works that deals with the resilience insist on the systems’ (defined as ensemble of “actors” widely speaking) abilities to anticipate, to live with and to recover from disasters. The resilience concept is more and more often used in risk management (Klein, 2003) because it inherently allows speaking about different types of systems. Some scholars focus on the ecosystems (Holling, 1973), or on socioecological systems (Folke, 2006) others on technical systems (De Bruijn, 2005; Lhomme et al, 2010) and others on social and political systems (Handmer et al., 1999; Reghezza-Zitt, 2009; Rioust, 2012). One of the most important aspect of the pretty wide diffusion of the resilience concept is it is used and developed at the same time by different type of scientists and by political institutions (United nations, European Union and also national and local governments).
