This article reports on a project, led jointly by Lancaster University and Save the Children UK, that used mobile, creative, and performance-based methods to understand children’s experiences and perceptions of the 2013–2014 UK winter floods and to promote their voices in flood risk management. We argue that our action-based methodology situated the children as “flood actors” by focusing on their sensory experience of the floods and thus their embodied knowledge and expertise. The research activities of walking, talking, and taking photographs around the flooded landscape, as well as model making and the use of theater and performance, helped to “mobilize” the children not only to recall what they did during the floods but also to identify and communicate to policy makers and practitioners how we can all do things differently before, during, and after flooding.
