It has long been recognized that groundwater plays a central role in the development of human societies. Groundwater resources are readily and reliably available compared with surface water resources. In many contexts, the presence of groundwater ensures the presence of life itself. The XXXII IAH (International Association of Hydrogeologists) and VI ALHSUD (Latin-American Association of Groundwater Hydrology for Development) Congress on Groundwater and Human Development, held in 2002, in Mar del Plata (Argentina), brought together over 400 participants from more than 40 countries. This lively gathering of water enthusiasts exchanged experiences of both fieldwork and research. Topics under discussion and scrutiny included: Groundwater and Quality of Life; Groundwater in Urban, Suburban and Rural Systems; Transboundary Aquifers; Hydrogeology of Large Plains; Coastal Aquifers; Methods for Groundwater Studies; and Education about Groundwater and Groundwater Management. This book contains selected papers, plenary lectures and material from workshops, illustrating the contribution of modern hydrogeology to sustaining humanity's thirst for fresh and safe water.
Sustainable groundwater development requires knowledge of the appropriate recharge and transport-processes. This is a prerequisite to understanding: (i) groundwater resources and their availability, and (ii) the dependence between groundwater and the environment. Conceptual understanding of groundwater flow at both temporal and spatial sc
The hydrogeologic environment of fractured rocks represents vital natural systems, examples of which occur on every continent. This book discusses key issues, methodologies and techniques in the hydrogeology of fractured rocks, summarizing recent progress and anticipating the outcome of future investigations. Forty-four revised and updated papers w
Groundwater resources are facing increasing pressure from consuming and contaminating activities. There is a growing awareness that the quantitative and qualitative preservation of groundwater resources is a global need, not only to safeguard their future use for public supply and irrigation, but also to protect those ecosystems that depend partially or entirely on groundwater to maintain their species composition and natural ecological processes. Known as groundwater dependent ecosystems (GDEs), they have been a fast-growing field of research during the last two decades. This book is intended to provide a diverse overview of important studies on groundwater and ecosystems, including a toolb...

Groundwater systems are vital to both society and the environment, supporting food production and many other ecosystem services. Sustainable management of this vital resource for future generations requires a sound understanding of how groundwater might respond to the inevitable changes in future climate. In this volume, recent developments within
This volume provides an analytical and facts-based overview on the progress achieved in water security in Latin America and the Caribbean (LAC) region over during the last decade, and its links to regional development, food security and human well-being. Although the book takes a regional approach, covering a vast of data pertaining to most of the LAC region, some chapters focus on seven countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico and Peru). A full understanding of LAC’s trends progress requires framing this region in the global context: an ever more globalized world where LAC has an increasing geopolitical power and a growing presence in international food markets. T...
Intensive use of groundwater has resolved the demand for drinking water and, through irrigation, has contributed to the eradication of malnourishment in many developing countries. The spectacular worldwide increase in groundwater use in the last decades, especially in arid and semi-arid regions, has been a silent revolution carried out by millions of small farmers. In some instances, groundwater abstraction has caused problems of quality degradation, excessive drawdown of groundwater levels, land subsidence, reduction of spring and baseflows or degradation of groundwater-dependent ecosystems. Most of these problems could be anticipated, mitigated, or even avoided with more active water agenc...
Presented at the International Association of Hydrogeologists Dijon Symposium, this book contains 43 selected papers, grouped into six topics, that address the following issues: large aquifers, resource assessment; large aquifers, water salinity and evolution; karstic and carbonate aquifer systems; geothermal aquifer systems; aquifer contamination studies; and aquifer monitoring systems and management. In celebration of the 150th anniversary of the publication of Darcy's Law, the volume includes a summary of Darcy's life and his contribution to science, and five invited contributions on modern methods to estimate the hydraulic conductivity of aquifers.
This book discusses integral groundwater management with scale flow issues and presents methods for defining, preventing, controlling, and mitigating negative environmental impacts related to groundwater. It highlights specific issues such as trans-boundary groundwater flow, groundwater recharge, groundwater mining, and groundwater flow in thick aquifers, and stresses the importance of the sustainable development of groundwater and its social and economic implications. The book will interest groundwater researchers, professionals, and students, providing new insights into the procedures and processes that are influenced by the scale of the groundwater flow system.
