Methods And Techniques Of Ground Water Investigation And Development

Groundwater Resources: Investigation and Development is a 13-chapter text that presents in a logical structure the various useful techniques for groundwater investigations. The introductory chapters deal with the general concepts of hydrology, types of aquifers and groundwater environments, and geographic and geologic topographic maps. These topics are followed by considerable chapters on groundwater investigation techniques, including geophysical and geochemical methods, drilling and isotope techniques, exploration, and pumping tests. The advantages and limitations of these techniques are examined. The discussion then shifts to interpretation and utilization of water level measurements and spring flow. The concluding chapters are devoted to determining the three boundaries enclosing the groundwater systems, namely, the fixed, movable, and arbitrary boundaries. These chapters also look into the principles of groundwater balances and groundwater reserves.

The definitive work on the subject, it offers you comprehensive and accurate coverage of the theory and techniques of ground water development. Provides not only a general overview of the topic with applications but also incorporates sufficient detail to be of use to professionals involved in any phase of ground water. Divided into three parts, the text traces the progression of the study of ground water from its origin through its development and exploitation. Part one deals mainly with the nature of ground water and where it can be found. Part two considers the parameters related to water well design and construction. In part three, there is a thorough review of well and well field operation, including monitoring for environmental protection. Although the focus is on high-capacity ground water producing installations, most of the material is also applicable to lower-yield wells.

This book presents an overview of techniques that are available to characterize sedimentary aquifers. Groundwater flow and solute transport are strongly affected by aquifer heterogeneity. Improved aquifer characterization can allow for a better conceptual understanding of aquifer systems, which can lead to more accurate groundwater models and successful water management solutions, such as contaminant remediation and managed aquifer recharge systems. This book has an applied perspective in that it considers the practicality of techniques for actual groundwater management and development projects in terms of costs, technical resources and expertise required, and investigation time. A discussion of the geological causes, types, and scales of aquifer heterogeneity is first provided. Aquifer characterization methods are then discussed, followed by chapters on data upscaling, groundwater modelling, and geostatistics. This book is a must for every practitioner, graduate student, or researcher dealing with aquifer characterization .

New exploration tools and techniques for a breakthrough paradigm of regional groundwater occurrence Fresh water is undoubtedly our most precious resource aside from the air we breathe, and the only commodity whose cost has steadily risen over time. At the same time, our understanding of the origins, pathways, and recharge mechanisms of the earth's most valuable "economic" mineral-groundwater-remains in the nineteenth century. It is ironic that this scientific anachronism is contributing to a global shortage of available fresh water supplies while oil, gas, and mineral discoveries have proliferated, vastly increasing the world's energy, precious metals, and industrial mineral reserves. Modern Groundwater Exploration details applications and results of proven twenty-first- century technologies and geological concepts adapted from the oil, gas, and mineral exploration industries for evaluating, developing, and managing previously undiscovered, massive, sustainable groundwater resources. Unprecedented in both its scope and authority, this timely book presents: * A new groundwater paradigm, coined Megawatershed, which accurately and comprehensively describes the earth's natural complex groundwater systems * Innovative exploration, drilling, and testing technologies that make major new ground-water sources more locatable and cost-effective to produce than ever before * Actual case studies in which megawatershed methods have identified vast quantities of new water and brought new hope to previously arid and desperately water-short locales * Chapters by former OECD DAC chairman Alexander R. Love, geopolitical analyst Dr. Ewan Anderson, and former director of the Trinidad and Tobago Water Resources Agency Dr. Utam Maharaj on the tremendous global implications of the megawater-shed paradigm. These experts explore the many beneficial applications of megawater-shed development, from macroeconomics to development of small island developing state (SIDS), and from critical environmental issues to water conflict resolution and the potential for a second "green revolution" The world's need for clean, dependable water is more urgent-and addressable-than ever before. Let Modern Groundwater Exploration introduce you to the authors' revolutionary megawatershed paradigm, along with the latest concepts and technologies for accessing vast reservoirs of groundwater-still today's safest, cleanest, and most plentiful water resource.

Groundwater Resource Development describes the basic steps involved in the development of a groundwater resource in the search for productive aquifers. This book discusses groundwater exploration, construction and testing of water wells, water quality and pollution considerations, and groundwater management. This text is comprised of 10 chapters and begins by presenting the steps in the evaluation, development, and management of an aquifer for water supply. The reader is then introduced to the fundamentals of groundwater, with emphasis on their origin and occurrence as well as the influence of porosity and permeability on groundwater accumulation, migration, and distribution. The chapters that follow focus on groundwater exploration, assessment of aquifer recharge and potential well yield, and factors affecting the quality of groundwater. The issues to be considered in well design and construction are also highlighted, along with aquifer hydraulics and pumping tests, groundwater pollution, and optimum management of groundwater resources. This text concludes with a chapter on techniques used in modeling the response of a groundwater reservoir. This book will be of value to geologists, civil engineers, environmental scientists, mathematicians, chemists, water well contractors, and others involved in the profession of water engineering.
