Download or read book Deposition and Erosion of Snow by the Wind written by Uwe Radok and published by . This book was released on 1968 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theories of uniform and non-uniform drifting snow are summarized with special emphasis on drift transport as a function of wind velocity. It is confirmed that the snow drift process involves a mobile surface layer of saltating particles, with a self-regulating thickness depending only on the surface stress and not on the snow concentration in the free air stream. It is shown to be a characteristic of snow (in contrast to sand or silt) that saltation and suspension drift occur side by side and that the latter reaches predominance as the wind velocity rises through the most common range of surface values. Theoretical reasons and observational evidence are produced for the view that deposition or erosion occurs on the snow surface during snow drift primarily as the result of mass flux convergence or divergence in the free air stream.

Download or read book Encyclopedia of Agrophysics written by Jan Gliński and published by Springer Science & Business Media. This book was released on 2011-06-07 with total page 1075 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

Download or read book Ravine Lands Greening for Livelihood and Environmental Security written by Jagdish Chander Dagar and published by Springer. This book was released on 2018-05-02 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, the only one of its kind on ravine lands, reflects the significant advances made over the past two decades in our understanding of gully erosion, its controlling factors, and various aspects of gully erosion. It also addresses central research gaps and unanswered questions, which include historical studies on gully erosion to better understand the different stages of their formation; appropriate measuring techniques for monitoring or assessing the geological and hydrological parameters and processes involved in gully development; interaction of hydrological and other soil degradation processes; ecology and biodiversity of fragile ravines; impact of climate and environmental changes on soil erosion processes; development of effective and reliable gully erosion models; effective gully prevention and control measures; watershed-based management options; and ravine rehabilitation policies. The present book is a highly timely publication and deals with various aspects of ravine ecology and rehabilitation of degraded lands, particularly with the aid of biological approaches. As such, it offers a valuable guide for all scientists working in the fields of soil conservation / rehabilitation and agroforestry, students, environmentalists, educationists, and policymakers. More importantly, it focuses on the rehabilitation of one of the world’s most degraded and fragile ecosystems, ensuring the livelihoods of resource-poor farmers and landless families living in harsh ecologies that are more vulnerable to climate change.
