This volume represents an effort to bring together communities of land-based hydrogeology and marine hydrogeology. The issues of submarine groundwater discharge and its opposite phenomenon of seawater invasion are discussed in this book from the geophysical, geochemical, biological, and engineering perspectives. This is where land hydrogeology and marine hydrogeology overlap. Submarine groundwater discharge is a rapidly developing research field. The SCOR and LOICZ of the IGBP have recently established a working group for this research. IASPO and IAHS under IUGG also recently formed a new joint committee "Seawater/Groundwater Interactions" to collaborate with oceanographers and hydrologists. The other articles introduce frontier research topics in more typical land and marine environments, such as fluid flow in karst aquifers, the biological aspects of fluids in sedimentary basins and submarine sedimentary formations, respectively, and vigorous fluid flow in subsea formations and their significance in global tectonics. Geochemical characteristics of hydrothermal activities at a number of active continental margins are also reviewed, and multidisciplinary geophysical constraints of the permeability of young igneous oceanic crust are summarized. A variety of driving mechanisms for fluid flow is discussed in land and subsea formations; terrestrial hydraulic gradient, buoyancy driven free convection, tidally induced flow, flow induced by tectonic strain, flow due to sediment compaction.

Historically, water has been treated as an inexhaustible resource. However, with the growth of population and development of industry and agriculture, freshwater demand has increased drastically, and its shortage felt in roughly 60% of the Earth. As early as 1931, renowned Russian scholar A.P. Karpansky wrote: "Water is not only a mineral resource, not only a means for developing agriculture. Water is a real culture bearer, it is a living blood, that creates life where there was none". Groundwater and the Environment: Remediation Applications and the Global Community covers one of the most important ecological problems - the impact on the environment of intensive groundwater pumping out. Drawing on more than a quarter century of study, Zektser analyses and makes conclusions about groundwater exploitation throughout the world. He focuses on the close connection of groundwater to the environment - its affect on surface water streams, reservoirs, seas, landscapes, and vegetation. The author demonstrates the importance of groundwater to the potable water supply, and its interaction with the environment. He stresses the significance of groundwater as a mineral resource. He provides techniques for assessing and mapping natural groundwater resources and develops these principles for studying water and hydrochemicals in coastal zones. In the last twenty years, the global awareness of groundwater as one of the most important natural resources has grown. Any changes in the groundwater causes changes in the environment. Groundwater and the Environment: Remediation Applications and the Global Community increases your ability to predict the possible changes to the environment and to follow the principle: "When using - protect, when protecting - use!"

Sustainable management of water resources is quickly increasing in importance on a global scale. An important piece of the puzzle is the characterization of marine water and determining its importance to geochemical budgets. To do this, submarine groundwater discharges must be carefully studied. Comprehensively exploring the subject, Submarine Groundwater presents quantitative data relating groundwater contribution to the water/salt balance of regional and global bodies of water. The authors examine different data-supported methods for studying submarine groundwater flow and discharge through case studies contributed by leading international scientists. They discuss the maintenance of optimal water, salt, temperature and hydrobiological regimes of inland seas and large lakes. The book covers subsurface water exchange between the land and sea as well as groundwater discharge to the seas. It also provides a review of experimental methods and numerical modeling that can be used for the evaluation of specific discharge data and the effect of groundwater on the salt balance of seas and oceans. Defining the field of marine hydrogeology as a science that studies submarine groundwater, its properties, circulation, and distribution, Submarine Groundwater delineates the role of quantitative assessment of subsurface water exchange between land and sea in predicting its changes under the influence of natural factors and human activity. It provides a framework for assessing different methods and making the best choice for various situations.

Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist’s tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.

The purpose of this study is to provide tools for water-resource management and land-use planning; to accomplish this purpose we (1) characterize the relationship of geology to ground-water conditions in the Glen Canyon and the unconsolidated valley-fill aquifers, (2) classify the groundwater quality of the Glen Canyon (east of the valley only) and valley-fill aquifers to formally identify and document the beneficial use of ground-water resources, and (3) apply a ground-water flow model using a mass balance approach to determine the potential impact of projected increased numbers of septic-tank systems on water quality in the valley-fill aquifer and thereby recommend appropriate septic-system density requirements to limit water-quality degradation

Originally published in 2004, this is a comprehensive review of the subject of the nature, causes, and consequences of fluid flow in oceanic crust, setting in context much research for the first time. The book begins with a concise review of the relatively brief history of its subject which began shortly after the dawning of plate-tectonic theory. It then describes the nature and important consequences of fluid flow in the sub-seafloor, ending with a summary of how the oceans are affected by the surprisingly rapid exchange of water between the crust and the water column overhead. The accompanying internet material includes a full and easily navigated set of diagrams and captions, references, and photos of research vessels, submersibles, and tools used in marine hydrologic studies. A valuable resource for graduate students and researchers of Earth Sciences and Oceanography.

Hydrogeology of Crystalline Rocks deals with deep groundwater in the granite and gneiss basement of the continents. It has become evident during the past years that highly mineralized water is present in an interconnected fracture network of the basement. Thus, the upper part of the crust of the continents can be viewed as an aquifer and investigated with tools common in hydrogeology. This book presents accounts on water-conducting features of crystalline rocks and summarizes the hydraulic properties of the basement. The volume includes reviews, new data and research on the often remarkable chemical composition of deep groundwater. Microbial processes in the deep basement aquifer are probably more important than previously thought. Two contributions focus on this recent extension of research of the biosphere to greater depth in the Earth. This book represents the first multidisciplinary and integrated account of deep groundwater hydrology in crystalline basement. It is of interest to hydrologists and hydrogeologists working with water in crystalline rocks, but also to solid earth geophysicists, geochemists and petrologists with an interest in fluids in the crust. Scientists involved in nuclear waste disposal programs and geothermal energy development will find a wealth of stimulating ideas in this volume.
