Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of numerical methods to model snow avalanches is of vital importance since in recent years there has been a notable increase in people exposed to risk areas due to the practice of mountain sports. The creation of tools capable of forecasting and simulating avalanches represents a step forward in minimizing the personal and economic costs caused by these natural disasters. With the collaboration of the Institut Flumen and the hydraulic modelling software Iber, it has been possible to develop a valid application for the simulation of snow avalanches using finite volumes. On account of this, the friction terms of the Saint Venant equations were previously modified to be valid for describing the behaviour of these non-Newtonian fluids. This Thesis analyses the parameters of friction, cohesion and slope to study how they affect the descent of avalanches. In addition, the numerical scheme is extended by incorporating the parameter of entrainment and four equations are developed that depend, independently, on velocity, snow height and bed shear stress. Thenceforth, the model is calibrated, and the equations are compared taking into account the field data of an avalanche registered in the area of Vallter, located in the Pyrenees of Girona. Finally, once the model has been determined to be sufficiently robust, the event of a historical avalanche that occurred in the ancient village of Àrreu -Pyrenees of Lleida- where nineteen inhabitants lost their lives is studied. For the first time, a study is proposed on how this fateful event happened, taking into account the existing historical documentation, and different current methods of protection and containment are proposed to prevent it from happening again.

This book was released on 2003-03-24 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: A "Sonderforschungsbereich" (SFB) is a programme of the "Deutsche For schungsgemeinschaft" to financially support a concentrated research effort of a number of scientists located principally at one University, Research La boratory or a number of these situated in close proximity to one another so that active interaction among individual scientists is easily possible. Such SFB are devoted to a topic, in our case "Deformation and Failure in Metallic and Granular M aterialK' , and financing is based on a peer reviewed proposal for three (now four) years with the intention of several prolongations after evaluation of intermediate progress and continuation reports. An SFB is terminated in general by a formal workshop, in which the state of the art of the achieved results is presented in oral or I and poster communications to which also guests are invited with whom the individual project investigators may have collaborated. Moreover, a research report in book form is produced in which a number of articles from these lectures are selected and collected, which present those research results that withstood a rigorous reviewing pro cess (with generally two or three referees). The theme deformation and failure of materials is presented here in two volumes of the Lecture Notes in Applied and Computational Mechanics by Springer Verlag, and the present volume is devoted to granular and porous continua. The complementary volume (Lecture Notes in Applied and Com putational Mechanics, vol. 10, Eds. K. HUTTER & H.

Available in PDF, EPUB and Kindle. Book excerpt: Winter recreation in the mountains has increased steadily over the past few years, and so has the number of deaths and injuries caused by avalanches. Staying Alive in Avalanche Terrain covers everything you need to know to avoid trouble in avalanche terrain: what avalanches are and how they work, common myths, human activities that lead to avalanche trouble, what happens to victims when an avalanche occurs, and rescue techniques. Provides step- by-step instruction for determining avalanche hazards, using safe travel technique, and making effective rescues.

Download or read book Himalayan Glaciers written by National Research Council and published by National Academies Press. This book was released on 2012-11-29 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.
Download or read book Geomorphological Fluid Mechanics written by N.J. Balmforth and published by Springer. This book was released on 2008-01-11 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geomorphology deals with some of the most striking patterns of nature. From mountain ranges and mid-ocean ridges to river networks and sand dunes, there is a whole family of forms, structures, and shapes that demand rationalization as well as mathematical description. In the various chapters of this volume, many of these patterns are explored and discussed, and attempts are made to both unravel the reasons for their very existence and to describe their dynamics in quantitative terms. Particular focus is placed on lava and mud flows, ice and snow dynamics, river and coastal morphodynamics and landscape formation. Combining a pedagogical approach with up-to-date reviews of forefront research, this volume will serve both postgraduate students and lecturers in search of advanced textbook material, and experienced researchers wishing to get acquainted with the various physical and mathematical approaches in a range of closely related research fields.
