Co-conception of integrated flood management solutions: riverscapes to facilitate dialog

When involved late in flood mitigation projects, biologists can suggest only minor changes. Conception should be multidisciplinary from the start. Riverscapes appear an excellent support to exchange information and share common conceptual views. Biologists thus summarize their expertise and local analyses, including a description of the potential biodiversity and processes. We built a riverscape typology for Polish mountain rivers and used it as a support to discuss compromises and adaptations for dry dams and river training. Translating the technical solutions into shift of types guide the choices. Serving a purpose, the typology is case-dependant and could be revised during a project. Riverscapes could also potentially be useful in multidisciplinary research.
