This book was released on 2013 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion is a serious environmental problem worldwide. Extensive research has been conducted identifying and quantifying erosion processes, measuring soil erosion, and evaluating the effectiveness of soil conservation practices. Accurately predicting soil erosion in space and time continues to be a challenge, and detailed spatial erosion data at field and watershed scales are needed to validate, calibrate, and improve erosion models. The Cs-137 and fingerprinting methods have been used to estimate soil erosion and sediment sources in many studies, but uncertainties exist in both methods. The purpose of this study was to evaluate these two methods and compare predictions with the Water Erosion Prediction Project (WEPP) model. The study area for this research was the Bull Creek watershed, located in west central Oklahoma. The Cs-137 method predicted reasonable long-term average soil erosion and deposition rates and integrated spatial and temporal changes in erosion/deposition. Compared to WEPP, the Cs-137 method needed less information and only required a one-time sampling. The fingerprinting method provided useful information about the sediment source contributions and performed best with two sources. For the Bull Creek study area, the mixing model predicted the source contribution with the lowest model errors; however, the results were not significantly different. The new Discriminate Function Analysis method may be a better method since it avoids spurious numerical solutions. When using the Cs-137 and the fingerprinting methods, sample collection and the proper application of particle size correction factors were critical. When there were two source types, the fingerprinting method and WEPP watershed model predicted similar source contributions. However, with three source types their predictions diverged. In addition, WEPP predicted significantly less sediment yield from the rangeland compared to the fingerprinting method. Combining erosion models with the fingerprinting method provides a more detailed evaluation of erosion predictions, which may result in improved land management recommendations and decisions.

Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis Karst Hydrogeology and Geomorphology by : Derek Ford
Download or read book Karst Hydrogeology and Geomorphology written by Derek Ford and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007
Book Synopsis Lectures in Isotope Geology by : E. Jäger
Download or read book Lectures in Isotope Geology written by E. Jäger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our colleagues from the French-speaking parts of Switzerland - the Suisses romands - and above all the committee of the 3rd Cycle, e Earth Sciences (3 Cycle, Sciences de la Terre) honored us by asking us to give a course on Isotope Geology for the year 1977. The course, entitled Evaluation et Interpretation des Donnees Isotopiques (eval uation and Interpretation of Isotopic Data), was intended to inform earth scientists, graduate and postgraduate, from the western Swiss Universities on the subject of Isotope Geology. Such courses usually consist of two parts: lectures and excursions. Thus, in March 1977, we gave such a two-week course at the Miner alogical Institute of the University of Berne. The first week was devoted essentially to the methods of dating, the second week to the behavior of stable isotopes. In July 1977, on the occasion of an excursion to the Central and Western Alps, we were able to demonstrate our results. Guest professors were invited to make contributions to the course.

Download or read book Paleolimnology written by Andrew S. Cohen and published by Oxford University Press. This book was released on 2003-05-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
