Download or read book Spatial Techniques for Soil Erosion Estimation written by Rupesh Jayaram Patil and published by Springer. This book was released on 2018-02-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel computation of the topographic LS factor of the USLE model to estimate spatial soil erosion. In developing countries, soil erosion is one of the main concerns as it adversely affects agriculture and reduces food production. Therefore, the author presents a particularly relevant approach, as he demonstrates how the C++ programming allows us to identify important erosion stages like detachment and deposition. He does this by assessing the annual rate of soil erosion from the Shakkar River watershed in India using distributed information and applying RS and GIS techniques. He also discusses different approaches that have been proposed to work out the influence of topography on erosion. Simulated and observed data of sediment loss are compared for the period 1992 to 2006.This book provides an easy-to-understand basic piece of soil erosion and hydrological research and reaches out to young researchers and students at the graduate and undergraduate level as well as applicants of soil erosion models.

Download or read book Fire Effects on Soil Properties written by Paulo Pereira and published by CSIRO PUBLISHING. This book was released on 2019-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires are occurring more frequently and affecting more of Earth's surface than ever before. These fires affect the properties of soils and the processes by which they form, but the nature of these impacts has not been well understood. Given that healthy soil is necessary to sustain biodiversity, ecosystems and agriculture, the impact of fire on soil is a vital field of research. Fire Effects on Soil Properties brings together current research on the effects of fire on the physical, biological and chemical properties of soil. Written by over 60 international experts in the field, it includes examples from fire-prone areas across the world, dealing with ash, meso and macrofauna, smouldering fires, recurrent fires and management of fire-affected soils. It also describes current best practice methodologies for research and monitoring of fire effects and new methodologies for future research. This is the first time information on this topic has been presented in a single volume and the book will be an important reference for students, practitioners, managers and academics interested in the effects of fire on ecosystems, including soil scientists, geologists, forestry researchers and environmentalists.

Download or read book Predicting Rainfall Erosion Losses written by Walter H. Wischmeier and published by . This book was released on 1978 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern, and topography. When these predicted losses are compared with given soil loss tolerances, they provide specific guidelines for effecting erosion control within specified limits. The equation groups the numerous interrelated physical and management parameters that influence erosion rate under six major factors whose site-specific values can be expressed numerically. A half century of erosion research in many States has supplied information from which at least approximate values of the USLE factors can be obtained for specified farm fields or other small erosion prone areas throughout the United States. Tables and charts presented in this handbook make this information readily available for field use. Significant limitations in the available data are identified.

Download or read book Instructor s Manual to Chris Park s The Environment written by Greg Lewis and published by Routledge. This book was released on 2012-11-12 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The very survival of the planet is at risk: human misuse of natural resources and disturbance of natural environmental systems is pushing the Earth to the limits of its capacity. The Environment is a lively, comprehensive introduction for environmental study, explaining how the environment functions, how environmental systems relate, and the ways in which people and environment interact. Focussing particularly on the environmental impacts of human activities, the book explains the ways in which an understanding of basic physical principles can help us to use the environment and its resources. Three particular approaches are adopted throughout: * a systems approach - highlighting the interactions and interrelationships between the environment's diverse parts * an interdisciplinary perspective - stepping back from individual subject focus to examine the complex breadth of the environment's diversity * a global perspective - incorporating stimulating examples drawn from around the world to illustrate broad global patterns and contrasts. The Environment explains the principles and applications of the different parts of the Earth's system: the lithosphere, the atmosphere, the hydrosphere, and explains the interrelationship across these systems. It explores the present environmental crisis, examines how the planet Earth fits into the wider universe, and explores human-environment interactions, to offer a clear understanding of the diverse and complex environment we live in and new ways of thinking about the way it is changing. Specific features include: * Lively, stimulating and accessible text * Superb illustrations: 4-colour plate sections * Case studies drawn from around the world, boxed within the text * Chapter summaries * Annotated further reading lists A Lecturer's Manual is available to accompany the text

Download or read book Measuring Modeling and Predicting the Seismic Site Effect written by Yefei Ren and published by Frontiers Media SA. This book was released on 2024-01-25 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: As recognized universally by both seismology and earthquake engineering communities, the amplitude and frequency content of ground motions are influenced by local site effects, including the effects of near-surface geologic materials, surface topographic and basin effects, and so on. Strong linkage between seismic site effect and earthquake damage has been commonly demonstrated from many past earthquakes. Therefore, quantitative and reliable evaluation of the seismic site effect is one of the crucial aspects in seismic hazard assessment and risk mitigation. With the significant advancement of modern seismic monitoring networks and arrays, huge amounts of high-quality seismic records are now being accumulated. This encourages us to measure the site responses and its associated uncertainty for selected seismic stations by some record-dependent approaches, such as horizontal-to-vertical spectral ratio (HVSR) measurements, generalized spectral inversion (GIT) methods, etc. Machine learning techniques also show significant promise in characterization of the near-surface geologic properties and prediction of site response. These data-driven approaches help us to better understand the physics of spatial and temporal variabilities of ground motions. Due to more and more site-specific data being captured, invoking non-ergodic assumptions in seismic response analysis has recently been a topic of great interest in the community. For specific site response analysis, numerical simulations are carried out to model the dynamic process of seismic waves propagating and scattering in the subsurface strata. With development of modeling capacity, great efforts have been taken to evaluate quantitatively the complex 2D and 3D effects on seismic site response.
