Chittaranjan Ray, Ph. D. , P. E. University of Hawaii at Mãnoa Honolulu, Hawaii, United States Jürgen Schubert, M. Sc. Stadtwerke Düsseldorf AG Düsseldorf, Germany Ronald B. Linsky National Water Research Institute Fountain Valley, California, United States Gina Melin National Water Research Institute Fountain Valley, California, United States 1. What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells — which are placed near the banks ofrivers —pump large quantities ofwater.

Book Description
This Second Edition of Environmental Impact Assessment Methodologies covers basic concepts and important methodologies. It details the prediction and assessment of impacts on soil and groundwater management, surface water management, biological environment, air environment, the impact of noise on the environment, and of socio-economic and human health impacts. This new edition contains an additional chapter on environmental risk assessment and risk management, a chapter on the application of remote sensing and GIS in EIA and a chapter with EIA case studies. Written clearly and concisely, it presents the fundamentals of EIA and how to apply these in practice. This volume is intended for a global audience of advanced students and practitioners in environmental management and planning.

Book Description
This edited volume is based on the best papers accepted for presentation during the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The book compiles a wide range of topics addressing various issues by experienced researchers mainly from research institutes in the Mediterranean, MENA region, North America and Asia. Remote sensing observations can close gaps in information scarcity by complementing ground-based sparse data. Spatial, spectral, temporal and radiometric characteristics of satellites sensors are most suitable for features identification. The local to global nature and broad spatial scale of remote sensing with the wide range of spectral coverage are essential characteristics, which make satellites an ideal platform for mapping, observation, monitoring, assessing and providing necessary mitigation measures and control for different related Earth's systems processes. Main topics in this book include: Geo-informatics Applications, Land Use / Land Cover Mapping and Change Detection, Emerging Remote Sensing Applications, Rock Formations / Soil Lithology Mapping, Vegetation Mapping Impact and Assessment, Natural Hazards Mapping and Assessment, Ground Water Mapping and Assessment, Coastal Management of Marine Environment and Atmospheric Sensing.

Book Description
As the frequency of near-surface mineral discoveries in the British Columbia Cordillera diminishes, exploration is more frequently focused on regions of high potential but mantled by unconsolidated sediments or drift, dominated by Quaternary deposits. This volume is a compilation of papers on various aspects of drift exploration, using examples from British Columbia. Topics of the papers include Quaternary geology, recognition of paleo-flow direction, drift potential mapping, drilling methods, glacial dispersal determination using indicator clasts, till geochemistry, biogeochemical sampling, lake sedimentology, laboratory techniques, shallow seismic methods, borehole analysis, and resistivity mapping. Case studies elaborating on drift exploration concepts are dispersed throughout the compilation.

Book Description
Watershed modeling is at the heart of modern hydrology, supplying rich information that is vital to addressing resource planning, environmental, and social problems. Even in light of this important role, many books relegate the subject to a single chapter while books devoted to modeling focus only on a specific area of application. Recognizing the

Book Description
AQUATOX: Modelling Environmental Risk and Damage Assessment, a new volume in the Developments in Environmental Modelling series, provides a single source for all AQUATOX applications, including basic equations, applications and examples on model implementation in various aquatic habitats (riverine, lacustrine and estuarine). The book presents a comprehensive reference source for AQUATOX model applications that can be used for an ecological modeling course at the graduate level. Throughout the text, chapter headings are organized to help users understand model building processes, state variables, and components. Case studies are provided to enhance learning and help readers assemble and calibrate their own AQUATOX applications. Includes a detailed description of AQUATOX equations for researchers and practitioners (including regulatory agencies) Presents study files, descriptions of implementation, and the data used as a starting point for new study applications Explores case studies of various sample applications and how specific problems are approached, including eutrophication issues in lakes and streams and natural resource damages in Estuarine Areas
