Название: Use of 137Cs for Soil Erosion Assessment ISBN: 925130050X ISBN-13(EAN): 9789251300503 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 60990.00 T Наличие на складе: Нет в наличии. Описание: The 137Cs method uses traces of nuclear activity to measure soil loss, and constitutes a relatively swift and cost-effective means of collecting data on soil erosion as compared to more conventional methods. This guide covers the main principles, sampling strategy, gamma spectroscopic measurements, estimation of erosion rates with conversion models, data interpretation and validation of erosion models. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture of the IAEA has been working on this method for over 20 years.

Описание: This publication deals with soil erosion and sedimentation. The quest for alternative techniques for assessing soil erosion, to complement existing methods, directed attention to the use of environmental radionuclides, in particular fallout as tracers to quantify rates and establish patterns of soil redistribution within the landscape.
Population growth in the Blue Nile Basin has led to fast land-use changes from forest to agricultural land, which resulted in speeding up the soil erosion processes producing highly negative impacts on the local soil fertility and agricultural productivity. The eroded sediment is transported downstream by water and sinks in the lower basin where it significantly reduces reservoir storage and irrigation canals capacity. The only effective solution to mitigate the sedimentation problem is to limit the sediment inputs from upstream by locally implementing erosion control practices. However, given the vastness and remoteness of the involved areas, this first requires the knowledge of the most critical zones.
The book identifies the sources of the sediment depositing in the Lower Blue Nile Basin and quantifies the amounts involved providing essential information for the planning and implementation of any interventions aiming at reducing soil erosion. The methods used consist of extensive field work covering most of the basin, watershed, hydrodynamic and morphodynamic modelling and, for the first time, the mineralogical analysis of the sediment at the sources and sinks. The method is successful in indentifying the areas providing most of the transported sediment, where it is recommended to start with erosion control practices.

Название: Soil erosion: The greatest challenge for sustainable soil management ISBN: 9251314268 ISBN-13(EAN): 9789251314265 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 24030.00 T Наличие на складе: Нет в наличии. Описание: This book, reviews the state of the art of all topics related to soil erosion. Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial, and it is these questions that can hamper efforts to implement sound erosion control measures in some parts of the world. Released in conjunction with the Global Symposium on Soil Erosion (May 2019), this publication argues that there are three main levers available to increase the adoption of soil control measures: enhanced extension leading to voluntary adoption; regulation coupled with effective enforcement, and economic incentives.

Описание: 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.
