“…This shows the importance of soft tools and their regular revision. To cope with these issues, geo-historical studies may be a good approach to the considering natural risks of a territory when documents are available [52]. Other soft management ideas have recently been mentioned for Kyushu Island, such as the need for a harmonized database of past disasters and the development of their use in disaster prevention and mitigation, or the improvement of evacuation systems [53].…”

On 5–6 July 2017, an unstable atmospheric condition caused an unusual concentration of rainfall above the Northern part of Kyushu Island, triggering a set of hydro-meteorological hazards. Within the affected area, the mountainous subwatershed of the Akatani River was significantly impacted by numerous landslides combined with debris flow and floods. National and local agencies deployed a plan of reconstruction to restore the floodplain and protect inhabitants. Regarding the hydrosystem in the Akatani watershed, this reconstruction project mainly focuses on the restoration of damaged protection systems and the construction of new infrastructures. Thus, this paper aims to explain the restoration plan of the Akatani River in terms of the strategic Japanese River System Sabo and then as a model of a national-scale spatial plan. It draws on (i) a literature review based on the historical evolution of Japanese protection systems and the River Sabo System; (ii) field surveys in 2019, 2022 and 2023, in conjunction with (iii) interviews with local, regional, and national officials; and (iv) a Geographical Information System analysis of previously and newly built protection systems through aerial photograph interpretation and geospatial data. Sabo works implemented in the Akatani watershed illustrate the engineering vision of Japanese river management. They also constitute a comprehensive system and include a downstream–upstream logic which echoes that of the River System Sabo. In addition, the disaster of July 2017 and the government’s response emphasize the continuous adaptation and improvement of the Japanese disaster management system, which mitigates severe disasters.

“…L'étude des données géohistoriques a permis d'établir une chronologie des crues du fleuve Charente sur la période récente. Elle vise ainsi à 1) mettre en évidence les évenements extremes sur le temps long (Martin et al, 2015), 2) effectuer une comparaison diachronique des évenements extremes (Brázdil et al, 2004 ;Elleder, 2015) et 3) analyser leur fréquence, leur saisonnalité, leur intensité, leur localisation (Barriendos et Rodrigo, 2006 ;Black et Law, 2004 ;McEwen, 1990 ;Brázdil et al, 2006), ainsi que leurs conséquences sur les riverains du fleuve et sur leur perception des inondations (Dupont, 2012).…”

“…These authors presented a statistical summary of the flood chronology, determined the meteorological causes for the occurrence of the floods, and proposed a cartographic representation of some of the major floods. More specific studies proposed a flood classification model valid in the long term, focusing on the specific analysis of the 1910 flood, used geohistorical data to analyze legal hazard mapping procedures 15 and address the change in risk over time and space (Martin et al, 2015a;2015b;. Despite this broad outlook, however, a detailed analysis of floods that have affected all major rivers in this territory is still lacking.…”

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 is the most common and damage-causing natural hazard in this area. In addition, existing inventories have often been compiled by scientists and technicians and are used for risk management in a top-down 15 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, northeastern 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 where information is shared between individuals, stakeholders, engineers, and scientists. This original approach aims at maximizing knowledge 20 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 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 25 municipalities, most of them since the end of the 15 th century, but over more than one millennium for the Rhine. Their main characteristics according to various typologies (seasonality, causes, severity, etc.) are analyzed. 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 the building of common flood risk knowledge are listed. 30Nat. Hazards Earth Syst.
