While agglomerations along the Rhine are confronted with the uncertainties of an increasing flood risk due to climate change, different programs are claiming urban river front sites. Simultaneously, urban development, flood management, as well as navigation and environmental protection are negotiating the border between the river and the urban realm. This produces complex spatial constellations between the river system and the urban realm with a diverse set of interdependencies, where programs have to synergize while adapting to dynamic water levels. Based on an expanding area at risk and the reliance on flood levels to remain within an acceptable spectrum for adaptive measures to be effective, Urban Flood Integration (UFI) involves border negotiations between the river and the urban realm where adaptation and mitigation ideally synergize.
Instead of a scientific approach that reduces complexity in order to reach a verifiable question, a post-normal science approach is chosen as an evaluation and working method applied within this research. The working method relies on literature studies, semi-structured interviews and empirical research through repeated site visits. The general heterogeneity of the case studies regarding their planning structure, status and time scales, data availability and the willingness by the agencies involved to provide usable information shapes the formal research structure.
