This book was released on 2018-07-25 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion is the most destructive land degradation process causing removal of soil, siltation of water reservoirs and pollution of water sources. Combating erosion needs reliable data on soil erosion rates, its dynamics and spatial distribution. Collecting such data with conventional methods requires great investment and long period of time. The 137Cs method for erosion assessment can address this problem. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture of the IAEA has been working on this method for more than 20 years. This publication provides a brief guidance on this method. It covers major components of 137Cs method starting from its principles, the sampling strategy, gamma spectroscopic measurements, estimation of erosion rates with conversion models, data interpretation and the use of 137Cs method for erosion models validation. The publication is suitable for a wide audience such as researchers, agricultural and environmental experts, decision makers, farmers and students

Download or read book Handbook of Erosion Modelling written by R. P. C. Morgan and published by John Wiley & Sons. This book was released on 2016-04-13 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The movement of sediment and associated pollutants over thelandscape and into water bodies is of increasing concern withrespect to pollution control, prevention of muddy floods andenvironmental protection. In addition, the loss of soil on site hasimplications for declining agricultural productivity, loss ofbiodiversity and decreased amenity and landscape value. The fate ofsediment and the conservation of soil are important issues for landmanagers and decision-makers. In developing appropriate policiesand solutions, managers and researchers are making greater use oferosion models to characterise the processes of erosion and theirinteraction with the landscape. A study of erosion requires one to think in terms ofmicroseconds to understand the mechanics of impact of a singleraindrop on a soil surface, while landscapes form over periods ofthousands of years. These processes operate on scales ofmillimetres for single raindrops to mega-metres for continents.Erosion modelling thus covers quite a lot of ground. This bookintroduces the conceptual and mathematical frameworks used toformulate models of soil erosion and uses case studies to show howmodels are applied to a variety of purposes at a range of spatialand temporal scales. The aim is to provide land managers and otherswith the tools required to select a model appropriate to the typeand scale of erosion problem, to show what users can expect interms of accuracy of model predictions and to provide anappreciation of both the advantages and limitations of models.Problems covered include those arising from agriculture, theconstruction industry, pollution and climatic change and range inscale from farms to small and large catchments. The book will alsobe useful to students and research scientists as an up-to-datereview of the state-of-art of erosion modelling and, through aknowledge of how models are used in practice, in highlighting thegaps in knowledge that need to be filled in order to develop evenbetter models.

Analysing climate data is an exciting challenge, which is increased by non-normal distributional shape, serial dependence, uneven spacing and timescale uncertainties. This book presents bootstrap resampling as a computing-intensive method able to meet the challenge. It shows the bootstrap to perform reliably in the most important statistical estimation techniques: regression, spectral analysis, extreme values and correlation. This book is written for climatologists and applied statisticians. It explains step by step the bootstrap algorithms (including novel adaptions) and methods for confidence interval construction. It tests the accuracy of the algorithms by means of Monte Carlo experiments. It analyses a large array of climate time series, giving a detailed account on the data and the associated climatological questions. This makes the book self-contained for graduate students and researchers.

Download or read book Urban Ecology Water Quality and Climate Change written by Arup K. Sarma and published by Springer. This book was released on 2018-03-14 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book brings together high-quality research contributions on ecological aspects of urbanization, water quality concerns in an urban environment, and climate change issues with a strong Indian focus under one umbrella. It includes several case studies that discuss urban water management, particularly highlighting the quality aspects. Urbanization is an ecological disturbance that the modern world accepts as essential in the absence of a better alternative that could provide an equal level of comfort. The prohibitive costs of eco-friendly production technologies are forcing the developing world to generate industrial waste that is detrimental to the environment. At the same time, the availability of adequate fresh water is another challenge for our climate-change impacted world. The scientific community is, therefore, searching for ways towards ecologically sustainable urban development. Discussing all these issues, this book offers a useful guide for academicians, researchers, practicing engineers, and managers dealing with diverse water-related problems in urban areas.
