Para comprender lo sucedido en la región de Atacama con los aluviones del 2015, se requiere ir más allá del mes de marzo y del contexto regional. Los estudios que se presentan en este libro articulan la situación actual con la precedente, para configurar la complejidad del fenómeno y sus impactos a partir de las señales entregadas por la historia. Tanto la sociedad como la naturaleza han manifestado sus desacoples y sus ajustes, por lo que el conocimiento científico que hemos generado busca también en ellos las explicaciones de lo ocurrido en la actualidad. Así, el análisis de las antiguas y nuevas amenazas se propone en este libro como la llave del conocimiento del riesgo al que se enfrenta la región, con la intención de retratar en el presente también el registro del pasado que lo conforma. Es esta profundidad la que nos permite pensar la experiencia del desastre como una oportunidad de reconocernos colectivamente en sus características, evitando repetir los mismos errores y reinventar las mismas soluciones.

Avalanches cause the highest number of fatalities in the Alps, threatening many areas and facilities, as well as transport and communications infrastructure. An integral part of avalanche protection is risk communication and warning, which is within the domain of the avalanche service of the Slovenian Environmental Agency. As part of the ‘Crossrisk Project’, the ZRC SAZU Anton Melik Geographical Institute has prepared a ‘Snow Field Manual’ which will allow for the standardised collection of field data on snow, snow cover and avalanches. This data forms the basis for determining the current avalanche hazard level. The ‘Snow Card’ supplement, which is an integral part of the manual, contains a condensed view of the most important contents and also includes two forms (there are a total of 14 forms in the manual) for entering the snow cover cross-section data. It also includes instructions for preparing and performing cross-sections of snow cover and avalanche tests. All information is provided along with a clear explanation key. Finally, a description of typical avalanche problems and types of avalanche hazards follows. The full applicability of the Snow Field Manual and the Snow Card is achieved by entering the digital data of the cross-section and the avalanche test into the appropriate web application. Snežni plazovi so naravna nesreča, ki v Alpah povzroči največ smrtnih žrtev, ogroža pa tudi številne površine in objekte ter prometno in komunikacijsko infrastrukturo. Sestavni del varstva in zaščite pred snežnimi plazovi je tudi obveščanje in opozarjanje, ki je v domeni lavinske službe, v Sloveniji Agencije Republike Slovenije za okolje. Na Geografskem inštitutu Antona Melika ZRC SAZU smo v okviru projekta Crossrisk pripravili priročnik bo omogočil standardizirano zbiranje terenskih podatkov o snegu, snežni odeji in plazovih, ki so temelj za določitev stopnje nevarnosti proženja snežnih plazov. V priročniku, katerega sestavni del je tudi snežna kartica - na njej sta poleg zgoščenega prikaza najnujnejših vsebin tudi dva obrazca (v priročniku 14) za vnos podatkov o prerezu - so navodila za pripravo in izvedbo prereza snežne odeje ter preizkusa plazovitosti. Pri vseh podatkih je naveden ključ za njihov vnos. Na koncu sledi opis značilnih plazovnih problemov oziroma tipov plazovne nevarnosti. Polno uporabnost snežnega priročnika in kartice dosežemo z e vpisom podatkov o prerezu in preizkusu plazovitosti na ustrezen spletni naslov, na katerem so obrazci v digitalni obliki.

This book presents an overview of volcanic debris avalanche deposits, which are produced by partial volcanic edifice collapse, a catastrophic natural phenomenon. It has been 40 years since the volcanic debris avalanche associated with the 1980 eruption of Mount St. Helens, and our understanding of these events has grown considerably in the interim. Drawing on these advances, the book addresses all aspects of volcanic debris avalanches. Though previously overlooked in field-based geological and volcanological studies, these deposits are now known to be associated with most volcanoes and volcanic areas around the world. The book presents state-of-the-art ideas on the triggering and emplacement mechanisms of these events, supported by field and analogue studies, as well as new simulations tools and models used to determine their physical characteristic and hazards.

This book reflects the latest research results in computer modelling of landslide-induced debris flows. The book establishes an understanding of the initiation and propagation mechanisms of landslides by means of numerical simulations, so that mitigation strategies to reduce the long-term losses from landslide hazards can be devised. In this context, the book employs the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) to investigate the mechanical and hydraulic behaviour of granular materials involved in landslides – an approach that yields meaningful insights into the flow mechanisms, concerning e.g. the mobilization of sediments, the generation and dissipation of excess pore water pressures, and the evolution of effective stresses. As such, the book provides valuable information, useful methods and robust numerical tools that can be successfully applied in the field of debris flow research.

Avalanches, debris, mudflows and landslides are common and natural phenomena that occur worldwide, predominantly in mountainous regions. With an emphasis on snow avalanches, this book sets out to provide 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 will help the practitioners in the field to better understand the physical input and provide them with a tool for their work. Originating from many lectures the authors have given over the years, this instructive volume brings the reader to the forefront of research - an aim also supported by an extensive bibliogrpahy of almost 500 entries. Avalanche Dynamics should be accessible to, and is intended for, a broad readership of researchers, graduate students and practitioners with backgrounds in geophysics, geology, civil and mechanical engineering, applied mathematics and continuum physics.
