Groundwater has long been an object of intense scrutiny. Only recently have methods become available that permit ecologists, hydrologists, and environmental scientists to assess the biotic and abiotic status of these all-important aquifers. - The dynamics of water movement through complex subterranean ecosystems - The biological organization and the factors that constrain these ecosystems - Alluvial and karst ecosystem functions - Contamination, management, and remediation

Groundwater Ecology and Evolution, Second Edition is designed to meet a multitude of audience needs. The state of the art in the discipline is provided by the articulation of six sections. The first three sections successively carry the reader into the basic attributes of groundwater ecosystems (section 1), the drivers and patterns of biodiversity (section 2), and the roles of organisms in groundwater ecosystems (section 3). The next two sections are devoted to evolutionary processes driving the acquisition of subterranean biological traits (section 4) and the way these traits are differently expressed among groundwater organisms (section 5). Finally, section 6 shows how knowledge acquired among multiple research fields (sections 1 to 5) is used to manage groundwater biodiversity and ecosystem services in the face of future groundwater resource use scenarios. Emphasis on the coherence and prospects of the whole book is given in the introduction and conclusion. - Provides a modern synthesis of research dedicated to the study of groundwater biodiversity and ecosystems - Bridges the gap between community ecology, evolution, and functional ecology, three research fields that have long been presented isolated from each other - Explains how this trans-disciplinary integration of research contributes to understanding and managing of groundwater ecosystem functions - Reveals the contribution of groundwater ecology and evolution in solving scientific questions well beyond the frontiers of groundwater systems

This updated and expanded edition provides a thorough understanding of the measurable properties of groundwater systems and the knowledge to apply hydrochemical, geological, isotopic, and dating approaches to their work. This volume includes question and answer discussions for key concepts presented in the text and the basic hydrological, geological, and physical parameters to be observed and measured. Chemical and Isotopic Groundwater Hydrology, Third Edition covers the chemical tools of groundwater hydrology, the isotopic composition of water and groundwater dating by tritum, carbon-14, Cl-36, and He-4, as well as the application of fossil groundwater as a paleoclimatic indicator.

Streams around the world flow toward the sea in floodplains. All along this transit, there is exchange of water between the stream itself and the surrounding sediments which form the floodplain. Many chemical, biological, and geological processes occur when water moves back and forth between streams and these flood plain sediments. Streams and Groundwaters focuses on the consequences of water flow between streams, their underlying sediments, and surrounding landscapes. Certain to appeal to anyone interested in stream ecology, the management of stream ecosystems, or landscape ecology, this volume should become a oft-opened reference.

A collection of articles on the ecology of North American desert springs, by authors from the fields of biology, botany, ichthyology, conservation, geology and law; and covering both the special traits of springs and the ways in which they might be managed in order to survive.

This accessible new textbook provides a thorough introduction toall aspects of groundwater systems and their management. Usingstraightforward language and analogies to everyday experiences, itexplains the origins, nature, and behavior of subsurface waterwithout resorting to complicated mathematics. Groundwater in the Environment draws on case studies andcutting-edge research from around the world, giving a uniqueinsight into groundwater occurring in a wide range of differentclimate zones and geological settings. This book: provides a robust, practical introduction to groundwaterquality, and a succinct summary of modern remedial technologies forpolluted groundwaters explores how groundwater fits into the wider naturalenvironment, especially in relation to freshwater ecosystems considers the vulnerability of groundwater systems and theeffects of pollution, climate change, land-use change, andoverexploitation examines human dependence on water and the effect that this hason groundwater systems presents vivid examples of geohazards associated with groundwaters explains the whys and wherefores of groundwater modeling examines competing philosophies of groundwater management,making the case for approaches which take social, economic andecological issues into account. Goundwater in the Environment provides an up-to-date,essential introduction for undergraduate students of environmentalsciences, geography and geology. It will also be invaluable toprofessionals working in various fields of natural resourcemanagement who need accessible information on groundwater but whoare reluctant to read conventional texts full of mathematicalnotation. For practicing hydrogeologists and engineers withoutformal training in freshwater ecology, this book provides a `crashcourse' in the new frontiers of groundwater management.

From the western United States to the Indian subcontinent, water issues have always been economic issues. Considered ubiquitous under the continents, groundwater varies considerably in depth, quality, accessibility, and availability. A unified discussion of groundwater and its economic importance, Groundwater Economics explores the application of e
