Mountain Risks : From Prediction to Management and Governance by Th. W. J. van Asch( )

10 editions published between 2013 and 2014 in English and held by 33 WorldCat member libraries worldwide

This book offers a cross disciplinary treatment of the rapidly growing field of integrated approaches in risk assessment in mountainous areas. All major aspects related to hazard and risk assessment, risk management, and governance are illustrated with a wide range of case studies. The first part of the book focuses on new techniques for assessing the natural hazards of different types of mass movements. State-of-the-art techniques for morphological characterization and monitoring of displacements are described. Computational advances are covered to explain the process systems and to quantify the hazards of fast and slow-moving landslides. In the second part of the book methodologies are included for assessing the impact of these natural hazards on the society in terms of risks. In this part, methodologies for defining the vulnerability of the elements at risk are shown and the use of run-out models for risk assessment of the dangerous rapid mass movements are evaluated. The third part of the book focuses on the response of society towards the problems of hazard and risk. It highlights the role of spatial planning, early warning systems and evacuation plans for risk management. It establishes practical thresholds for acceptable and tolerable risks and emphasizes the importance of education and communication to society. Audience The book is of interest to a wide range of experts from related disciplines, practitioners and stakeholders to demonstrate the importance of an integrated approach for all aspects of risks in mountainous areas

Mouvements de fluides et processus de déstabilisation des versants alpins : Apport de l'étude de l'instabilité de Séchilienne by Aurélien Vallet( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

Pore water pressure build-up by recharge of underground hydrosystems is one of the main triggering factors ofdeep-seated landslides. Consequently, the characterization of landslide deformation mechanisms requires athorough knowledge of the hydrogeological processes triggering the destabilization. Anisotropic andheterogeneous media combined with landslide deformation render classical hydrogeological investigationsunsuitable. Hydro-mechanical processes which lead to slope failure of deep-seated landslides are complex andare influenced by the evolution of the landslide deformation through time. This thesis aims at improving theunderstanding of the relationships between precipitation and displacement velocity based on the study of theSéchilienne deep-seated landslide. A time-related monitoring of natural and artificial tracers allows to define aconceptual groundwater flow model despite a limited number of hydrogeological points of interest. Fluid porepressures are rarely measured on landslide sites and, instead the groundwater recharge is generally used as themost relevant parameter. A parsimonious, yet robust, guideline workflow to calculate time series of groundwaterrecharge is developed. Based on the conceptual groundwater flow model and the recharge calculation, a waveletanalysis coupled to a numerical model integrating time-dependent parameters allows to characterize therelationship between precipitation and displacement velocity and to simulate the creep deformation resulting ofindirect hydro-mechanical coupling (multi-year trend of displacement velocities). The characterization of thehydrogeological processes controlling the destabilization allowed to define a statistical rainfall threshold basedon an innovative multi-dimensional approach

Détection et caractérisation multi-méthodes des éboulements rocheux by Gaëlle Le Roy( )

1 edition published in 2020 in English and held by 1 WorldCat member library worldwide

Parmi les mouvements de terrain, les éboulements rocheux restent le danger le plus imprévisible et le plus fréquent en région alpine. Dans un contexte d'urbanisation croissante des régions montagneuses, les éboulements représentent un risque croissant pour les communautés locales et les infrastructures. Cette thèse vise à développer une association pertinente de méthodes pour la surveillance des éboulements en couplant des mesures de relief à un suivi sismologique, afin d'améliorer la compréhension de la dynamique des éboulements. Ce travail a été principalement réalisé dans le massif de la Chartreuse (Isère, Alpes Françaises), et en particulier sur deux falaises, le mont Saint-Eynard et le mont Granier. Par photogrammétrie, nous avons obtenu des Modèles Numériques de Terrain (MNTs) des falaises. Ce suivi nous a permis de réaliser des inventaires de chutes de blocs et des analyses de fréquence d'occurrence. Cela nous a également fourni des informations sur les emplacements des éboulements ainsi que leurs configurations structurales. L'association des MNTs et du suivi sismique des éboulements nous a permis d'étudier les relations entre les propriétés des éboulements (emplacement, volume, géométrie, propagation, etc.) et le signal sismique induit par ceux-ci. Les caractéristiques des signaux sismiques (durée et énergie, contenu fréquentiel, forme de l'enveloppe) diffèrent selon le mode de propagation des évènements (écoulement en masse, chute libre, glissement, rebondissement, ...). Une sélection d'évènements ayant le même type de propagation permet d'obtenir une caractérisation plus précise des propriétés des éboulements que si l'on mélange différents types d'événements. Dans le cas d'éboulements subissant une chute libre, nous avons analysé le signal sismique des phases de détachement et du premier impact. Nous avons obtenu des relations entre certains paramètres des signaux sismiques et l'énergie potentielle des éboulements, leur hauteur de chute libre ou leur volume. Pour les événements de type écoulement en masse, nous avons observé une loi d'échelle entre l'énergie sismique d'un éboulement et son volume. En couplant les MNTs et les enregistrements sismiques, nous sommes ainsi en mesure de reconstruire le déroulement des éboulements avec une datation précise et une estimation de volume correcte. Des lâchers contrôlés de blocs ont été réalisés en laboratoire et in-situ pour élargir nos observations sur les éboulements de falaise
The impact of an exhibition on risk awareness of the general public in mountainous areas( )

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

Abstract: This study investigates the impact of an exhibition on natural hazards on risk awareness of the inhabitants of the Ubaye Valley in southern France. Risk communication practices need to be effective to contribute to disaster reduction, but their impact is rarely evaluated. Using a pre-test/post-test research design as well as a longitudinal study, changes in awareness of adults, teenagers and children were measured. The responses to a questionnaire were analyzed using non-parametric tests. The questionnaire dealt with several factors determining or influencing awareness: attitudes to risk, previous experiences of emergencies, exposure to awareness raising, ability to mitigate/prepare/respond, worry level, self-reported awareness, hard knowledge and demographic characteristics. Generally, risk awareness was higher after visiting the exhibition. The exhibition had most impact on visitors that had experienced few natural hazards or that were little informed a priori. In contrast to teenagers and children, the awareness of adults increased only for risk in general and not for specific natural hazards. Moreover, the results show that the exhibition was more effective in raising awareness of the hazards that occur rarely. For more frequent and more locally occurring hazards, such as debris flows, other means of communication should be considered
Développements méthodologiques en géophysique haute résolution pour la caractérisation hydro-mécanique de glissements de terrain argileux by Julien Gance( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

The objective of this research project is the improvement of our knowledge of the elementary processes controlling the post-rupture hydrological behavior of clayey landslides. It should allow understanding, reproducing and possibly forecasting their behaviors by the use of adapted hydro-mechanical models. This work consists in the improvement and the development of geophysical parameters processing and interpretation methodologies in clayey and heterogeneous medium. The main objectives of this work are : 1. The improvement of geophysical and geodesic methods to measure the internal geometry and structure of the landslide. 2. The characterization of possible relationships between landslide internal geometry and structure, presence of discontinuities, slope hydrology and deformations. 3. The development and improvement of methodology for the detection and imaging of preferential flows in a fissured and deformable medium. 4. The spatial and temporal characterization of the hydrological response of the slope. A high resolution inversion algorithm of the first seismic arrivals is developed. It uses the Fresnel volumes for the retropropagation of the residuals and the assumptions of a finite-bandwidth source signal. It permits to recover a high resolution image of the internal structure of the landslide. The seismic P-wave attenuation is also inverted to characterize surface fissured zones. Photogrammetric methods are used to characterize and quantify the surface deformations. A method alternative to image correlation is developed, based on the target detection and tracking. The link between changes in deformation regime along the profile and the existence of surface fissures is finally discussed. The previous data are integrated inside a geometric model trough data fusion. Using numerical modeling, we verify if the state of stress computed is related to the surface fissure density distribution. A methodology of correction of the geometrical effect of fissures on apparent resistivity is developed. Different types of inversion artefacts, linked to the presence of surface fissures, are identified. The ability of the proposed method to limit this artifact is tested. A methodology of selection and processing of the time-lapse ERT data is developed. The short electrical response (from several hours to several days) to natural rainfall events is analyzed and conceptual hydrological responses to these rainfall events are proposed
Landslide recognition and monitoring with remotely sensed data from passive optical sensors by André Stumpf( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Landslide inventory mapping and monitoring are indispensable for hazard assessment and disaster management. The enhanced availability of VHR satellites, UAVs and consumer grade digital cameras offers a great potential to support those tasks at regional and local scales, and to complement established techniques such as in situ instrumentation, radar, andlaser scanning. A lack of image processing tools for the efficient extraction process-relevant information from different types of optical imagery still complicates the exploitation of optical data and hinders the implementation of operational services. This doctoral thesis is dedicated to the development and application of image processing techniques for the mapping,characterization and monitoring of landslides with optical remote sensing data. A comprehensive review of innovative remote sensing techniques for landslide monitoring shows the potential and limitations of available techniques and guides the selection of the most appropriate combination of sensors - platforms - image analysis methods according to the observed process and end-user needs. For the efficient detection of landslides after major triggering events at the regional scale, a method for rapid mapping combining image segmentation, feature extraction, supervised learning is developed. For detailed landslide investigations at the local scale, this study elaborates image processing chains for detection of surface fissures in time-series of UAV images as geo-indicators of landslide activity, the measurement of horizontal surface displacements from VHR satellite images using stereo-photogrammetric and image correlation methods, and 3D measurements from terrestrial photographs based on multi-view open-source photogrammetry
