Avalanches, mudflows and landslides are common and natural phenomena that occur in mountainous regions. With an emphasis on snow avalanches, this book provides a survey and discussion about the motion of avalanche-like flows from initiation to run out. An important aspect of this book is the formulation and investigation of a simple but appropriate continuum mechanical model for the realistic prediction of geophysical flows of granular material.
Avalanche dynamics equations are used to estimate flow heights, velocities, specific thrust pressure, maximum specific weight of avalanche debris, and runout distance for 12 avalanche case studies from the Colorado Rocky Mountains. Suggestions are made for using this engineering approach for avalanche zoning and land use planning.
Mountains have captured the interests and passions of people for thousands of years. Today, millions of people live within mountain regions, and mountain regions are often areas of accelerated environmental change. This edited volume highlights new understanding of mountain environments and mountain peoples around the world. The understanding of mountain environments and peoples has been a focus of individual researchers for centuries; more recently the interest in mountain regions among researchers has been growing rapidly. The articles contained within are from a wide spectrum of researchers from different parts of the world who address physical, political, theoretical, social, empirical, environmental, methodological, and economic issues focused on the geography of mountains and their inhabitants. The articles in this special issue are organized into three themed sections with very loose boundaries between themes: (1) physical dynamics of mountain environments, (2) coupled human–physical dynamics, and (3) sociocultural dynamics in mountain regions. This book was first published as a special issue of the Annals of the American Association of Geographers.
Technical yet accessible, The Avalanche Handbook, 3rd Edition, covers the formation, character, effects, and control of avalanches; rescue techniques; and research on understanding and surviving avalanches. Illustrated with nearly 200 updated illustrations, photos and examples, the revised edition offers exhaustive information on contributing weather and climate factors, snowpack analysis, the newest transceiver search techniques, and preventative and protective measures, including avalanche zoning and control. It contains new information on the unique characteristics of alpine snow, snow slab instability, terrain variables, skier triggering of avalanches, and the nature of avalanche motion. Plus brand-new chapters on the elements of backcountry avalanche forecasting and the decision-making process.
This book offers a timely overview of theories and methods developed by an authoritative group of researchers to understand the link between criticality and brain functioning. Cortical information processing in particular and brain function in general rely heavily on the collective dynamics of neurons and networks distributed over many brain areas. A key concept for characterizing and understanding brain dynamics is the idea that networks operate near a critical state, which offers several potential benefits for computation and information processing. However, there is still a large gap between research on criticality and understanding brain function. For example, cortical networks are not homogeneous but highly structured, they are not in a state of spontaneous activation but strongly driven by changing external stimuli, and they process information with respect to behavioral goals. So far the questions relating to how critical dynamics may support computation in this complex setting, and whether they can outperform other information processing schemes remain open. Based on the workshop “Dynamical Network States, Criticality and Cortical Function", held in March 2017 at the Hanse Institute for Advanced Studies (HWK) in Delmenhorst, Germany, the book provides readers with extensive information on these topics, as well as tools and ideas to answer the above-mentioned questions. It is meant for physicists, computational and systems neuroscientists, and biologists.
Snow avalanches can have highly destructive consequences in developed areas. Each year, avalanche catastrophes occur in mountain regions around the globe and cause unnecessary fatalities and severe damage to buildings and infrastructure. In some mountainous regions, especially in the European Alps, technical avalanche defence structures are built to increase the level of safety for inhabited areas; however, new infrastructure such as roads, railway lines and tourist facilities cause new risk potential in hazardous areas. As a result, the demand is increasing for technical avalanche protection solutions. Avalanche defence structures and protection systems are used in most inhabited mountain regions worldwide. During the last decades, technical avalanche protection has evolved from a specialist field to an independent engineering branch that has gained importance in alpine countries such as Austria, Italy, France and Switzerland, as well as in other countries such as Canada, Iceland, Norway and USA. This work is the first comprehensive, English-language overview of technical avalanche protection and establishes state-of-the-art best practices in the field. It covers the fundamentals of avalanche protection technology and includes plans, dimensions, construction and maintenance of defence structures. The editors have collaborated with an international team of experts from Austria, Canada, France, Iceland, Italy, Japan, Norway, Switzerland and USA to produce this landmark handbook.
With major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, the two-volume Handbook of Environmental Fluid Dynamics presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the study of environmental motions. It also offers critical discussions of environmental sustainability related to engineering. The handbook features 81 chapters written by 135 renowned researchers from around the world. Covering environmental, policy, biological, and chemical aspects, it tackles important cross-disciplinary topics such as sustainability, ecology, pollution, micrometeorology, and limnology. Volume One: Overview and Fundamentals provides a comprehensive overview of the basic principles. It starts with general topics that emphasize the relevance of environmental fluid dynamics research in society, public policy, infrastructure, quality of life, security, and the law. It then discusses established and emerging focus areas. The volume also examines the sub-mesoscale flow processes and phenomena that form the building blocks of environmental motions, with emphasis on turbulent motions and their role in heat, momentum, and species transport. As communities face existential challenges posed by climate change, rapid urbanization, and scarcity of water and energy, the study of environmental fluid dynamics becomes increasingly relevant. This volume is a valuable resource for students, researchers, and policymakers working to better understand the fundamentals of environmental motions and how they affect and are influenced by anthropogenic activities.
