Download or read book Instabilities in alpine permafrost strength and stiffness in a warming regime written by Yuko Yamamoto and published by vdf Hochschulverlag AG. This book was released on 2014-08-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpine permafrost exists at high altitude at lower latitudes, such as in the Swiss Alps. Accelerating climate change, including rising mean annual air temperature and extreme rainfall conditions in alpine regions induces permafrost degradation. The warming of permafrost causes accelerated creep of rock glaciers, due to increased unfrozen water content and higher deformability of the ice phase. Recently, the development of deepening depressions has been observed in several rock glaciers in Switzerland, and the changes in land surface characteristics and drainage systems may initiate slope instabilities in rock glaciers. The main aim of this thesis is to characterise the strength and stiffness of alpine frozen soil in rock glaciers. To this end, the geotechnical response, such as creep and failure of frozen soil was investigated through a triaxial stress path testing programme with novel measurement systems for detecting acoustic emissions and measuring volumetric change. In addition, the resistance to crack initiation and propagation was investigated through a beam bending test programme on rectangular artificially frozen soil specimens, using the acoustic emission measurement system. The evaluation of laboratory tests on artificially frozen soil specimens implied that the development of deep depressions in rock glaciers occurs through differential creep and thermal degradation, and that the rate of deformation has the potential to lead to instabilities in rock glaciers. A comparison of the simulation results with the experimental data demonstrated that the semi-coupled model was successful in simulating the most important aspects of the temperature-dependent stress-strain relationship for the frozen soil behaviour that was measured at the element scale. This thesis contributes to an understanding of the variations in geotechnical response of alpine permafrost, by investigating the behaviour of artificially frozen soil specimens experimentally and numerically with time and temperature under specific stress paths. However, further investigations are necessary to assess the long-term stability of rock glaciers affected by climate change.

Download or read book Safeguarding Mountain Social Ecological Systems vol 1 written by Stefan Schneiderbauer and published by Elsevier. This book was released on 2023-12-01 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safeguarding Mountain Ecosystems: A Global Challenge provides an overview of the relevant research in mountain regions worldwide, identifying existing challenges and providing an understanding of the diversity of mountain ecosystems in different regions. Mountain ecosystems are increasingly vulnerable to modified climate conditions and other global changes (demographic, migration, urbanization). In this time of change, efforts for sustainable development in mountain ecosystems deserve all the attention, especially in synergy with the United Nations’ International Frameworks, including the Sustainable Development Agenda 2030, the Sendai Framework for Disaster Risk Reduction, the Paris Agreement, and the New Urban Agenda.Sections underline the importance of mountain regions for humanity at global, regional and local scales, describe the challenges of safeguarding mountains and possible solutions worldwide, and scrutinize regional specificities of the major mountain ranges, describing the challenges and opportunities of each. Final sections reflect on applications and technologies that address and solve major problems. Focuses on existing challenges for mountain regions around the world Presents specific case studies of mountain ecosystems from major mountain ranges Features contributions from representatives of UN Agencies and research experts from the addressed regions, offering a very interdisciplinary view on challenges and opportunities
Download or read book Engineering Geology for Society and Territory Volume 1 written by Giorgio Lollino and published by Springer. This book was released on 2014-08-23 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is one out of 8 IAEG XII Congress volumes and deals with climate change affecting different natural processes and environments, such as slope dynamics, water courses, coastal and marine environments, hydrological and littoral processes and permafrost terrain. Due to climate change, major effects are also expected on territorial planning and infrastructure, particularly in extreme climate regions. The volume and its contents aim to analyze the role of engineering geology and the solutions it may offer with respect to the ongoing environmental changes. Contributions regard the modeling of both the factors and the effects induced by climate change. Potential impacts of the climate change on the common practice and routine work of engineering geologists are also analyzed, with particular attention to the risk assessment and mitigation procedures and to the adaptation measures adopted. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: environment, processes, issues and approaches. The congress topics and subject areas of the 8 IAEG XII Congress volumes are: Climate Change and Engineering Geology. Landslide Processes. River Basins, Reservoir Sedimentation and Water Resources. Marine and Coastal Processes. Urban Geology, Sustainable Planning and Landscape Exploitation. Applied Geology for Major Engineering Projects. Education, Professional Ethics and Public Recognition of Engineering Geology. Preservation of Cultural Heritage.

Download or read book Permafrost Soils written by Rosa Margesin and published by Springer Science & Business Media. This book was released on 2008-10-31 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the Earth’s biosphere is characterized by low temperatures. Vast areas (>20%) of the soil ecosystem are permanently frozen or are unfrozen for only a few weeks in summer. Permafrost regions occur at high latitudes and also at high ele- tions; a significant part of the global permafrost area is represented by mountains. Permafrost soils are of global interest, since a significant increase in temperature is predicted for polar regions. Global warming will have a great impact on these soils, especially in northern regions, since they contain large amounts of organic carbon and act as carbon sinks, and a temperature increase will result in a release of carbon into the atmosphere. Additionally, the intensified release of the clima- relevant tracer gas methane represents a potential environmental harzard. Significant numbers of viable microorganisms, including bacteria, archaea, p- totrophic cyanobacteria and green algae, fungi and protozoa, are present in per- frost, and the characteristics of these microorganisms reflect the unique and extreme conditions of the permafrost environment. Remarkably, these microorg- isms have been reported to be metabolically active at subzero temperatures, even down to ?20°C.

Download or read book Periglacial Landscapes of Europe written by Marc Oliva and published by Springer Nature. This book was released on 2023-01-01 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively presents the geography of landforms linked to periglacial processes across Europe. The landscape of the European cold climate regions, both at high latitudes and in mountainous environments, represent the lingering, minimal expression of the glaciers. In addition, periglacial elements can be found in temperate regions, where temperatures no longer favor periglacial processes, so landforms are therefore inherited from previous cold phases. The book is divided into five parts: an introductory section on climate variability responsible for periglacial dynamics across Europe; a second part including 3 blocks on periglacial landforms in southern, central and northern Europe; and a final chapter providing a more general perspective on the impact of periglacial processes on the landscape of Europe. The book offers a valuable reference guide for scientists from all disciplines interested in cold climate processes, as well as readers outside academia (territorial managers, environmentalists, mountaineers, politicians, engineers, etc.).
