معرفی چند کتاب جدید:
----------
Introduction to Process Geomorphology. Vijay K. Sharma. CRC Press, 2010. 435 pp. ISBN: 9781439803370. Price: $119.95. Introduction to Process Geomorphology provides an integrative approach to the process dynamics and the origin of landforms by the contemporary processes involved in their evolution. The author highlights the physical and chemical laws governing the activity of the earth-surface processes in specific environmental stress conditions and puts forward competing hypotheses on the evolution of landforms, and discusses the bases of internal geologic processes for the explanation of the tectogenic features of the earth. Landforms also evolve over a long period of cyclic and geologic time, inheriting the imprints of past process rates and/or process domains. The principles and methods of evaluating the signature of environmental change are highlighted in the text by citing suitable studies. The process-form relationships provide the building blocks also for the optimum utilization of the land resources of the earth, and quantitative assessment of the stability of geomorphic systems and the quality of environment. The approach in this part of the text enables readers to gain an in-depth understanding of the application of the principles of geomorphology to the evaluation, planning and management of the earth’s resources for sustainable development.
Soil Physics with HYDRUS: Modeling and Applications. David E. Radcliffe and Jiri Simunek. CRC Press, 2010. 388 pp. ISBN: 9781420073805 Price: $99.95. Numerical models have become much more efficient, making their application to problems increasingly widespread. User-friendly interfaces make the setup of a model much easier and more intuitive while increased computer speed can solve difficult problems in a matter of minutes. Co-authored by the software’s creator, Dr. Jirka Šimunek, Soil Physics with HYDRUS: Modeling and Applications demonstrates one- and two-dimensional simulations and computer animations of numerical models using the HYDRUS software. Classroom-tested at the University of Georgia by Dr. David Radcliffe, this volume includes numerous examples and homework problems. It provides students with access to the HYDRUS-1D program as well as the Rosetta Module, which contains large volumes of information on the hydraulic properties of soils. The authors use HYDRUS-1D for problems that demonstrate infiltration, evaporation, and percolation of water through soils of different textures and layered soils. They also use it to show heat flow and solute transport in these systems, including the effect of physical and chemical nonequilibrium conditions. The book includes examples of two-dimensional flow in fields, hillslopes, boreholes, and capillary fringes using HYDRUS (2D/3D). It demonstrates the use of two other software packages, RETC and STANMOD, that complement the HYDRUS series.
Notes from the Ground: Science, Soil, and Society in the American Countryside. Benjamin R. Cohen. Yale University Press, 2009 - Technology & Engineering. 272 pages. Notes from the Ground examines the cultural conditions that brought agriculture and science together in nineteenth-century America. Integrating the history of science, environmental history, and science studies, the book shows how and why agrarian Americans—yeoman farmers, gentleman planters, politicians, and policy makers alike—accepted, resisted, and shaped scientific ways of knowing the land. By detailing the changing perceptions of soil treatment, Benjamin Cohen shows that the credibility of new soil practices grew not from the arrival of professional chemists, but out of an existing ideology of work, knowledge, and citizenship.
Soil Atlas of the Northern Circumpolar Region. Catalogue Number: LB-NA-23499-EN-C. ISBN: 978-92-79-09770-6, ISSN: 1018-5593. Euro 25. The atlas describes the origin and major characteristics of the different soil types that can be found in this environment. The atlas discusses the possible impacts of climate change on permafrost-affected soils and explains the critical role that they play in the global climate and global carbon cycles. The distribution of soil types for the entire northern circumpolar region can be visualised in a comprehensible manner by the lay-person. Information on the major soil types is presented in detail on twenty six map plates (the atlas has an A3 page size giving a dramatic A2 spread for maps). In a novel exercise, the World Reference Base for Soil Resources has been used as a framework for correlating knowledge from diverse national soil classification systems into a single, coherent, inter-continental product. The atlas illustrates the diversity of soil in the permafrost and seasonally frozen environments through a series of maps supported by explanatory and easily readable texts, high quality photographs and descriptive graphics. The atlas presents the reader with a series of maps that show the variation of soil properties in a circumpolar context and from a polar perspective, allowing comparisons to be made across international boundaries. In addition, larger scale maps show the distribution of major soil types by regions with descriptions of the major issues. http://eusoils.jrc.ec.europa.eu/library/maps/Circumpolar/Download.cfm
