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.

Описание: This book presents a new perspective on the sedimentation processes in the White Sea, based on a multidisciplinary research study conducted between 2001 and 2016. It provides a comprehensive review and discusses the latest research findings on the ecosystem of this sub-arctic zone.The topics addressed include suspended particulate matter as a main source and proxy of the sedimentation processes in the White Sea; vertical fluxes of dispersed sedimentary matter and absolute masses in the White Sea; and the development history and quaternary deposits of the modern White Sea basin. The authors closely examine the abundance and species composition of microalgae associations and the environmental conditions in the bottom sediments of the White Sea, namely, heavy metal accumulation and aliphatic and polycyclic aromatic hydrocarbons. The book ends contain a summary of the key conclusions and recommendations. Together with the companion volume Biogeochemistry of the Atmosphere, Ice and Water of the White Sea: The White Sea Environment Part I, it offers an essential source of information for postgraduate students, researchers, and stakeholders alike.
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.
