“…Yet, the importance of public involvement and participation in environmental decision-making is now widely acknowledged and promoted, especially regarding risk management and/or knowledge capitalization (Scarwell and Laganier, 2004;Kenyon, 2007;Koehler and Koontz, 2008;Fournier, 2010;Collombat, 2012;When et al, 2015). Participative knowledge capitalization is particularly relevant in the European context of flood risk management.…”

Abstract. Despite the strong societal impact of natural hazards, their documentation remains incomplete, with only a few inventories exceeding the past two centuries. Surprisingly enough, this also applies to Europe, a densely populated territory, and to floods, which along with storms are the most common and damage-causing natural hazard in Europe. In addition, existing inventories have often been compiled by scientists and technicians and are used for risk management in a top-down manner, although the participation of all parties concerned has been recognized as a key factor for disaster reduction. To address this double paradox, the present article presents the regional flood risk observatory ORRION for the Alsatian region, north-eastern France, and its very rich data content. Stemming from two successive interdisciplinary and transnational French–German research projects, ORRION was designed as a participative online platform on which information is shared between individuals, stakeholders, engineers, and scientists. This original approach aims at maximizing knowledge capitalization and contributes to building a common knowledge base for flood risk. ORRION is organized by events including all river floods that have likely arisen from a single synoptic situation. For each event, it documents information sources, date of occurrence, causes, and consequences in terms of damage and affected river basins and municipalities. ORRION has contributed toward renewing our knowledge of flood hazard and risk in the target area. Notably, here, long chronicles of floods are derived for 13 rivers, the Rhine and most of its main Alsatian tributaries and for all Alsatian municipalities, most of them since the end of the 15th century but over more than one millennium for the Rhine. Their main characteristics according to various typologies (seasonality, causes, severity, etc.) are analysed. Major developments over the study period related to sources, land use, and/or climate change are identified. The advantages and limitations of the approach are discussed, and the potential to expand both data exploitation and build common flood risk knowledge is outlined.

“…Autrement dit, le risque doit être étudié pour et sur un territoire donné. Cette réflexion prônant une articulation entre le risque et le territoire bénéficie d'une littérature scientifique internationale importante (Scarwell, Laganier, 2004 ;Muller-Mahn, 2012 ;Veyret et al, 2004 ;Beucher, 2008). De manière concise, les études géographiques du risque doivent tenir compte de la relation riche et complexe entre ces deux éléments, risque et territoire, sous peine de ne prendre en compte qu'une vision partielle du territoire, à savoir son rôle de support du risque (November, 2002).…”

“…As soon as the industrial period began, and even more so after the First World War, urbanisation widely stretched into flood plains. Dikes, dams, hydraulic works were progressively reinforced along French rivers to prevent main floods (Scarwell and Laganier [2]). French rivers were no longer regarded as just waterways but also as major water resources that had to be managed (times of the "houille blanche" i.e.…”

“…Through an analysis of the evolution of settlements by GIS, by the study of planning documents and by an historical analysis of flood protection orientations, we are going to characterize the balance between urban development and flood management in the middle Loire Valley. We will show the shift from the unlimited urban sprawl during the last decades (2) to its end with the recognition of the dangerousness of the Loire River by official protection documents (3). This forces districts to adapt their development according to the flood risks (4).…”

Flood plains experience a continuous stress between the prevention of natural risks and the need of space for new activities. Mankind is increasing its occupation of flood plains in spite of recurrent floods, following a certain aptitude to forget risk. This paper analyzes this conflicting situation, especially in the middle Loire Valley. The aim is to understand which factors have oriented the urban sprawl into the flood plains, through an analysis of the evolution of settlements by GIS, by the study of planning documents and by an historical analysis of flood protection orientations. The study shows that under the weight of a reinforced legal arsenal and some other pressures, the districts have begun to give up this unlimited and irrational urbanization. New strategies are appearing. They are split between the intent to give more space to the river and the intent to invent an urban planning design that is more compatible with flooding. This contribution theorizes that a new paradigm is emerging, combining geographical localization and mental representations of risk.
