L'eau à découvert by Luc Abbadie( )

2 editions published in 2017 in French and held by 27 WorldCat member libraries worldwide

Indispensable à la régulation du climat, au développement de la vie sur Terre, au maintien des écosystèmes, aux populations, au développement de l'agriculture, de l'industrie comme à la production d'énergie, l'eau est un élément vital. Il convient donc, dans un contexte de changement global, d'analyser dans toute sa diversité la place et le rôle de l'eau et de se donner ainsi les moyens de mieux la préserver. Autour de cet enjeu qui engage toute l'humanité, Agathe Euzen, Catherine Jeandel et Rémy Mosseri ont réuni près de cent cinquante contributions, visant à apporter un éclairage sur chacun des domaines et des approches que couvre cette thématique. Quelle est l'origine de l'eau? Son rapport avec l'apparition de la vie? Quel rôle a-t-elle joué dans l'histoire de la planète et dans le développement de la vie végétale, animale et humaine? Quel est son cycle? Quelles sont ses propriétés chimiques? Comment les sociétés se sont-elles emparées de cet élément précieux? Allons-nous manquer d'eau? L'eau est-elle source de conflits? Comment l'eau est-elle gérée? Comment recycle-t-on une eau polluée? Quels sont les risques pour la santé mondiale? Quels sont les grands enjeux liés à l'eau au xxie siècle? Comprendre et proposer des solutions à ces défis majeurs est l'intention de cet ouvrage
Conduite à contre-courant. Les pratiques de mobilité dans le Gard : facteur de vulnérabilité aux crues rapides by Isabelle Ruin( Book )

3 editions published between 2007 and 2008 in French and held by 3 WorldCat member libraries worldwide

Les crues rapides sont à l'origine des catastrophes naturelles présentant le plus fort taux de mortalité du fait de leur rapidité d'occurrence et de leur extrême violence. Surprenant les populations dans leurs activités quotidiennes, elles frappent en particulier les personnes en déplacement pendant la crise, si bien que les automobilistes représentent jusqu'à la moitié des décès. Les recherches hydro-météorologiques ont permis d'augmenter les échéances de prévision et de diminuer en partie les incertitudes associées, alors qu'en matière de vulnérabilité sociale beaucoup reste à faire. Les experts appellent à une approche compréhensive intégrant sciences sociales et naturelles pour s'intéresser aux réponses des populations. C'est dans ce cadre que s'inscrit cette recherche sur la vulnérabilité des pratiques de mobilité lors de crues rapides. Deux sources d'inadaptation de ces pratiques sont envisagées : d'une part la réticence à sortir d'un mode de fonctionnement « quotidien » au profit d'un fonctionnement « de crise » ; d'autre part l'inadéquation des représentations spatio-temporelles individuelles du phénomène de crues rapides. Utilisant l'enquête par questionnaires ou la cartographie mentale auprès d'un total de 1 428 résidents et touristes en visite dans le Gard, nous avons montré que les pratiques de mobilité à risque sont le résultat de la combinaison de trois facteurs : l'exposition spatio-temporelle, les représentations du risque sur la route ainsi que les contraintes familiales et professionnelles quotidiennes des résidents. Sur la base de ce diagnostic de vulnérabilité, des pistes d'actions préventives ciblées sont ensuite proposées
Extrêmes hydro-météorologiques et exposition sur les routes : Contribution à MobRISK : modèle de simulation de l'exposition des mobilités quotidiennes aux crues rapides by Mohamed Saif Shabou( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

Flash floods are considered as ones of the most dangerous natural hazard due to their rapidness and suddenness that leave little time for exposed people to protect themselves. Although the relatively small spatial extension of those events, several studies showed strong human impacts regarding the number of affected people. Recently, daily mobility is pointed at as important social factor increasing individual exposure and vulnerability to flash flooding : almost half of the victims are motorists trapped while travelling on flooded roads. Therefore, several studies have been conducted for assessing roads' sensitivity to flooding in the Gard area, frequently exposed to sever flash flood events.This thesis goes a step further by integrating social dimension in order to quantify and analyze road users' exposure to flash flood during their itineraries. It contributes to the development of MobRISK : A simulation model for assessing motorists' exposure to roads submersion by integrating individual travel-activity patterns and behavioral adaptation regarding weather disruptions. In order to assess population exposure to September 2002 flash flood event, we conducted an application of MobRISK in a study area located in the north-ouest of the Gard department.The results show that risk of flooding is mainly located in principal road links with considerable traffic load. However, a lag time between the timing of roads' submersion and persons crossing these roads contributes to reduce the potential vehicle-related fatal accidents. It is also found that socio-demographic variables have significant effect on individual exposure and that young working males are the most exposed persons to road flooding. Finally, different behavior scenarios are built and tested by integrating individual travel adaptation decisions regarding perceived weather disruptions. The comparison of motorists' exposure for each scenario highlights the important role of risk attitudes and threat evaluation processes on reducing population exposure.Thus, the proposed model demonstrates the benefits of considering spatiotemporal dy- namics of population exposure to flash flood and presents an important improvement in exposure assessment methods. Such improved characterization of road users' exposure can present valuable information for flood risk management services and emergency planning

Forecasting of flash-flood human impacts integrating the social vulnerability dynamics by Galateia Terti( )

1 edition published in 2017 in English and held by 2 WorldCat member libraries worldwide

In the 21st century the prediction of and subsequent response to impacts due to sudden onset and localized flash flooding events remain a challenge for forecasters and emergency managers. Structural measures and/or advances in hydrological forecasting systems alone do not guarantee reduction of fatalities during short-fuse flood events. The literature highlights the need for the integration of additional factors related to social and behavioral vulnerability processes to better capture risk of people during flash floods. This dissertation conducts a theoretical analysis as well as an analysis of flash flood-specific historic fatalities to explain complex and dynamic interactions between hydrometeorological, spatial and social processes responsible for the occurrence of human life-threatening situations during the "event" phase of flash floods in the United States (U.S.). Individual-by-individual fatality records are examined in order to develop a classification system of circumstances (i.e., vehicle-related, outside/close to streams, campsite, permanent buildings, and mobile homes). The ultimate goal is to link human vulnerability conceptualizations with realistic forecasts of prominent human losses from flash flood hazards. Random forest, a well-known decision-tree based ensemble machine learning algorithm for classification is adopted to assess the likelihood of fatality occurrence for a given circumstance as a function of representative indicators at the county-level and daily or hourly time steps. Starting from the most prevalent circumstance of fatalities raised from both the literature review and the impact-based analysis, flash flood events with lethal vehicle-related accidents are the subject to predict. The findings confirm that human vulnerability and the subsequent risk to flash flooding, vary dynamically depending on the space-time resonance between that social and hazard dynamics. For example, it is found that younger and middle-aged people are more probable to get trapped from very fast flash floods (e.g., duration close to 5 hours) while participating in daytime outdoor activities (e.g., vehicle-related, recreational). In contrary, older people are more likely to perish from longer flooding inside buildings, and especially in twilight and darkness hours when rescue and/or evacuation operations are hindered. This reasoning places the importance of situational examination of dynamic vulnerability over generic and static conceptualizations, and guides the development of flash flood-specific modeling of vehicle-related human risk in this thesis. Based on the case study of May 2015 flash floods with a focus in Texas and Oklahoma, the model shows promising results in terms of identifying dangerous circumstances in space and time. Though, critical thresholds for the prediction of vehicle-related incidents need to be further investigated integrating local sensitivities, not yet captured by the model. The developed model can be applied on a daily or hourly basis for every U.S. county. We vision this approach as a first effort to provide a prediction system to support emergency preparedness and response to flash flood disasters over the conterminous U.S. It is recommended that the flash flood disaster science community and practitioners conduct data collection with more details for the life-threatening scene, and at finer resolutions to support modeling of local temporal and spatial complexities associated with human losses from flash flooding in the future
Envisager la vigilance crues comme système organisationnel : les conditions de sa robustesse en territoires inondés dans le bassin Adour-Garonne (Sud-Ouest de la France) by France Daupras( )

Improving flood forecasting has become a technological race with major advances over the last 20 years. Moreover, communication technologies improvements have significantly increased the speed of warning dissemination. However, flood warning systems present inherent uncertainties and vulnerabilities. The present thesis questions how stakeholders involved in the French Flood Warning System (FFWS) deal with those uncertainties and vulnerabilities to achieve the aim of anticipation. Our approach is based on a conceptual model making use of the concept of robustness. We have applied this model to several flooded territories in the Adour-Garonne basin (France). Taking into account both vulnerability and coping capacities, we analyse the socio-spatial conditions that allows the robustness of the FFWS. A qualitative research methodology (150 semi-directive interviews) was adopted for the case studies. We demonstrate that (1) some vulnerabilities of the institutional warning can be overcome by the coping capacities and territorial knowledge of people at risk ; (2) the improvement of the FFWS can be achieved by the combination of both vernacular and scientific knowledges, and by an adaptation to local context ; (3) the reinforcement of the FFWS robustness depends on the upholding and the development of collective action, integrating people at-risk, crisis management services and forecasters through regular meetings and flood training exercises outside flooding periods. Such actions allow reinforcing collective action during crisis situations through the development of trustfulness
