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
The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state regional restoration program is underway for America’s most urbanized estuary. Synthesis of the Long Island Sound ecosystem is needed to integrate knowledge across disciplines and provide insight into understanding and managing pressing issues, such as non-point sources of pollution, coastal development, global climatic change, and invasive species. Currently, there is a need for a comprehensive volume that summarizes the ecological and environmental dynamics and status of Long Island Sound and its myriad ecosystems. It has been 30 years since a comprehensive summary of Long Island Sound was prepared and 50 years since the pioneering work of Gordon Riley. Major advances in estuarine science are providing new insights into these systems, and yet, the condition of many estuaries is in decline in the face of continuing coastal development. There is an opportunity to lay a foundation for integrative coastal observing systems that truly provide the foundation for improved decision-making. This book will provide a key reference of our scientific understanding for work performed over the past three decades and guide future research and monitoring in a dynamic urbanized estuary.

Book Description
This edited book presents a novel collection of field-based empirical studies on the Quaternary geomorphology of the Lower Ganga Basin. The book covers a wide range of topics discussing various geomorphological facets of the Lower Ganga and its subsidiary rivers focussing on laterites, palaeoenvironment and palaeogeomorphology, palaeo-coastal landforms, neo-tectonism, tidal-fluvial dynamics, extra-channel geomorphology and channel-pattern adjustment among others. Various methodologies were applied ranging from historical records and religious texts to state-of-the-art remote sensing and GIS techniques. The book appeals to all scientists and post-graduate students of geomorphology and related areas who want to acquire detailed knowledge of the geology and geomorphology of the Lower Ganga Basin or are in search of new methodologies for studying the feedback mechanisms between forms and processes.

Book Description
Egyptian coastal lakes and wetlands are among the most productive wetland ecosystems in the world. This volume explores their current status and how it can be maintained and improved. It describes the five Northern coastal lakes, their origin, physical and chemical properties and current development activities, and discusses the challenges facing these lakes, such as shrinking, pollution, degradation, and adaptive management. Further topics include hydrodynamics and modeling techniques, as well as strategies for the sustainable development of these valuable resources. The book closes with a concise summary of the conclusions and recommendations presented in the chapters. As such, it offers an invaluable resource for the academic community and postgraduate students, as well as for environmental managers and policymakers.

Book Description
This book provides an overview of the ecological indicators of landscape dynamics in the context of geographical landscape integration. Landscape dynamics depicts every change that occurs in the physical, biological, and cognitive assets of a landscape. To understand and interpret the complex physical, biological, and cognitive phenomena of landscapes, it is necessary to operate conceptually and practically on a broad range of spatial and temporal scales. Rapid land use changes have become a concern to environmentalists and planners because of their impacts on the natural ecosystem, which further determines socioeconomic dynamics. In this regard, the book discusses case studies that share new insights into how landscape patterns and processes impact small creatures, and how small creatures in turn influence landscape structure and composition. In turn, the relevant aspects of land use and land cover dynamics are covered, and the multi-faceted relationship between the substrata and ecological community is highlighted. The book is unique in its focus on the application of spatial informatics such as automatic building extraction from high-resolution imagery; a soil resource inventory for meeting the challenges of land degradation; hydrological modeling; the temporal variation analysis of glacier area and the identification and mapping of glacial lakes; morphometric analysis of river basins; and the monitoring and modeling of urban sprawl, among other features.
