Download or read book Coupled DEM CFD Analyses of Landslide Induced Debris Flows written by Tao Zhao and published by Springer. This book was released on 2017-05-22 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2024-08-21 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the intensification of global climate and environmental change has led to frequent occurrence of natural hazards. Various types of natural hazards always overlap and interact, or occur in a chain reaction, with a wide range of impacts and a long period of time, resulting in serious disaster losses. Typically, major earthquakes and geological hazards, extreme meteorological hazards, large-scale floods and droughts, marine disasters, and forest and grassland fires, as well as their compound and chained hazards are among the key factors affecting human life safety and world economic development. To better our understanding of disaster prevention, mitigation, and relief, it is thus pivotal to facilitate advanced perception, intelligent early warning, accurate prevention, and efficient rescue of natural hazards. This Research Topic aims to collect both Original Research and Review articles addressing the state-of-the-art advances of theories and methodologies in all types of natural hazards. Studies underlining the compound and chained relationship between different hazards are in particular welcomed. Potential themes include, but are not limited to: • Mechanisms of formation, evolution, and disaster process of multiple natural hazards as well as their compound and chained natural hazards • Model and scenario development regarding whole process control, chain breaking of key nodes, and precise prevention of major natural hazard chains • Methods and applications on detection, identification, database establishment, and spatiotemporal evolution law analysis of natural hazard sources • Technologies on intelligent early warning and refined risk assessment of compound and chained natural hazards. • Rescue equipment and investigation of post-disaster community reconstruction

This book was released on 2024-01-29 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of the 21st century, global environmental problems have become increasingly prominent, and extreme weather events have become more frequent. The irrational development and excessive construction of underground space have also led to various disasters, such as landslides, collapses, debris flows, and ground collapses. According to the data released in the National Geological Disaster Bulletin, 133899 geological disasters have occurred in China from 2009 to 2019, of which landslides accounted for 71%, collapses for 19%, and debris flows for 8%, and ground collapses for 2%. The number of casualties and economic losses caused by rock and soil disasters are the greatest in the world. Therefore, a good understanding of disaster-causing mechanisms of rock and soil has a strong theoretical and practical significance for the safe construction of diversified geotechnical projects.

Download or read book Water Related Natural Disasters in Mountainous Area volume II written by Jia-wen Zhou and published by Frontiers Media SA. This book was released on 2024-03-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In mountainous areas, due to the unique geological and topographical conditions, and along with the impact of global climate change, extreme rainfall events often occur and induce natural disasters such as flash floods, debris flows, landslides, dammed lakes and others. These water-related natural disasters (WRNDs) frequently occur around the world, such as the July 29th 1998 debris flow and landslide dam at Capricorn Creek in Mount Meager Volcanic Complex (southern Canada), the flash flood of 20th August 2018 in Raganello Gorge (southern Italy), and the 2007 summer floods in the United Kingdom. WRNDs are more serious in Southeast Asia particularly in Southwest China, where many places suffer from such disasters in the flood season every year, such as the May 20th 2012 flash flood/debris flow among the hit area of Wenchuan earthquake, the June 24th 2017 Xinmo Catastrophic landslide in Mao county and in 2018 the two sequential landslide-dammed lake events at Jinsha River. These WRNDs not only cause heavy casualties and property losses but also destroy the ecological environment. These WRNDs are not only the concern of government managers and engineers, but also deserve more in-depth study from researchers. Formation and evolution mechanisms of WRNDs are very complicated, and influenced by several aspects, such as geological and topographical conditions, hydrometeorological conditions, geomaterial properties, rainfall history and flow condition, and others. Field and laboratory tests can help us to better understand the related mechanism behind the disasters. Theoretical and empirical models, modeling and numerical methods can provide more reasonable evaluation and forecasting results of WRNDs, but a more in-depth understanding is needed. Furthermore, for the risk control and hazard prevention and mitigation, new equipment and technologies have been developed and have achieved some progress in recent years, but the fast and effective emergency treatments for WRNDs need more attention.

This book was released on 1966 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: An equation proposed for the calculation of forces on a sphere accelerating in a viscous fluid (Odar and Hamilton, 1964 AD-602 777) is verified by comparing the velocities of spheres falling under gravity in a viscous fluid with those calculated from the equation. The excellent agreement between the experimental and calculated values suggests wide application for the equation. (Author).

This book was released on 2007-05-17 with total page 659 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amongst the thematic topics discussed are global frequency, impacts on society, analysis of initial rock slope failure, monitoring of rock slope movement, analysis and modeling of post-failure behaviour, volcanic landslides, and influences of massive rock slope failure on the geomorphological evolution of mountain regions. Regional contributions include reports on rockslides and rock avalanches in Norway, western Canada, the Andes of Argentina, the Karakoram Himalaya, the European Alps, the Appennines, and the mountains of Central Asia. Rockslides and rock avalanches in the Central Asian republics of the former Soviet Union are discussed in detail for the first time in an English-language book. These landslides include the 1911 Usoi rockslide, that dammed 75 km-long Lake Sarez, and the 1949 Khait rock avalanche that may have killed up to 28,000 people. Both landslides were earthquake-triggered and both are located in Tajikistan. An additional highlight is a detailed description and analysis of large-scale artificial rock avalanches triggered by underground nuclear explosions during the testing programme of the former Soviet Union.
