Contaminated bottom sediments and their negative impacts on water quality are a major problem in surface waters. Sediment and ContaminantTransport in Surface Waters provides a quantitative understanding of the transport of sediments and hydrophobic contaminants. With an emphasis on fine-grained, cohesive ...
Problems faced by geotechnical engineers and geologists who are currently involved in ground water seepage analysis and evaluation of contaminanttransport problems are covered in the publication. Permeability-hydraulic conductivity-is only one of the many parameters required to predict groundwater ...
Contaminated bottom sediments and their negative impacts on water quality are a major problem in surface waters throughout the United States as well as in many other parts of the world. Even after elimination of the primary contaminant sources, these bottom sediments will be a main source of contaminants for ...
In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and ...
This handbook concerns the general field of groundwater from an engineering perspective. It covers the several disciplines concerned with the design and control of flow and contaminanttransport in groundwater. Each chapter is authored by a specialist in the topic treated, and special care has been taken to ...
Interest in hydraulic conductivity of soils and waste contaminanttransport has increased substantially in recent years, largely due to environmental concerns. Assessments of potential contamination at a site are possible only if accurate information is available concerning the hydraulic conductivity of ...
Diffusion in Natural Porous Media: ContaminantTransport, Sorption/Desorption and Dissolution Kinetics introduces the general principles of diffusion in the subsurface environment and discusses the implications for the fate and transport of contaminants in soils and groundwater. Emphasis is placed on ...
Flocculation is a dominant process in aquatic environments, fundamental to water and wastewater treatment systems. Environmental and economic consequences of flocculation include sedimentation and contaminanttransport, which can bring about habitat destructions and affect human health via deterioration of ...
Presents a thorough introduction to groundwater systems analysis and optimization terminology, principles, and techniques Identifies which S-O approaches are appropriate for different types of groundwater quantity (hydraulic optimization) and quality (contaminanttransport optimization) problems, ...
This new publication reviews recent advances in contaminated sediments-management-related research and focuses on the engineering aspects of contaminanttransport, erosion, stability, monitoring, and modeling. It identifies both established and innovative physico-chemical and biological tests and methods ...
The European Arctic and Alpine regions are experiencing large environmental changes. Increased temperatures and precipitation, reduction in sea ice and glacier ice, the increased level of UV-radiation and the long-range transportedcontaminants are challenging new stress factors for both terrestrial and ...
The ‘standard’ two-equation turbulence models, used widely in industry, cannot be directly used in depth-averaged modeling. Till now, the vast majority of quasi 3D numerical tools just can provide one depth-averaged 2-eq. k-ε model for modeling side-charge problem on single-level grid. Due to the absence of one ‘universal’ model in the turbulence modeling theory, ...
This book describes the sources of water contamination by PAHs and their transportation and fate in natural aquatic systems. It then discusses, from the analytical chemist’s view, how to determine the presence of PAHs in water and wastewater, and the changes in PAH concentration during treatment processes. The ...
Environmental Geomechanics covers a broad class of problems where deforming geomaterials are involved, usually coupled with fluid flow and transport of some substance. Transport of contaminants and other substances may occur in the fluids, e.g. water, water vapour and air, filling the pores of geomaterials as ...
A complete treatment of the theory and practice of groundwater engineering, The Handbook of Groundwater Engineering, Second Edition provides a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the ...
A complete treatment of the theory and practice of groundwater engineering, The Handbook of Groundwater Engineering, Second Edition provides a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the ...
Billions of dollars are spent annually on surface and groundwater remediation, generating a demand by the public and government for effective modeling of contaminant fate and transport, with the hope that accurate models will result in the effective application of remediation efforts-and an efficient ...
Completely revised and updated, Fundamentals of Ecotoxicology, Second Edition presents a treatment of ecotoxicology ranging from molecular to global perspectives. The authors focus first on lower levels of organization and then extend their discussion to include landscape, regional, and biospheric topics, imparting a perspective as broad as the the problems facing practicing professionals. See ...
