Book Description
In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste

Book Description
This book contains the results and findings of the advanced research carried out in a pilot area with a thorough investigation of the structure and functioning of an aquifer in a granitic formation. It characterizes the hard rock aquifer system and examines its properties and behavior as well as systematically details the geophysical, geological and remote sensing applications to conceptualize such an aquifer system.

Book Description
Current manuals and technical books on ground water hydrology contain relatively little specific information on ground water in hard rocks areas, that is mainly igneous and metamorphic rocks of the Precambrian shield areas. This work is intented to fill this gap and to inform of the possibilities of finding and developing water resources in hard rocks areas

Book Description
Direct Current Geoelectric Sounding: Principles and Interpretation provides a comprehensive review of the Schlumberger method of geoelectric sounding, as well as current methods of interpretation. It explores the theoretical foundations of geoelectric sounding, the relative advantages and limitations of the two symmetrical arrangements for vertical electrical sounding, the techniques of interpretation for Wenner sounding curves, and dipole sounding. This volume is based on educational materials used in the study of geoelectric sounding. It begins with an overview of the theory of current flow in a horizontally stratified Earth, followed by a discussion of how the resistivity of the ground is measured. The book explains the current flow in a homogeneous anisotropic and horizontally stratified Earth, the principle of equivalence, and vertical electrical sounding. Moreover, it presents the basic principles and procedures for the construction of theoretical master curves. Asymptotic values of Schlumberger curves, the principle of reduction of two layers and of a three-layer Earth, and Tagg's method of interpretation are also discussed. The book explains the interpretation by curve-matching, characteristics of dipole electric sounding, and geological applications of electrical resistivity sounding. Engineering problems and application examples with self-explanatory diagrams are provided at the end of the chapters. This book will benefit undergraduate and postgraduate students who want to broaden their understanding of exploration geophysics, as well as professional exploration geologists and geophysicists, civil engineers, agricultural scientists, and researchers.

Book Description
FIELDS AND WAVES IN ELECTROMAGNETIC COMMUNICATIONS A vital resource that comprehensively covers advanced topics in applied electromagnetics for the professional Electromagnetism (EM) is a highly abstract and complex subject that examines how exerting a force on charged particles is affected by the presence and motion of adjacent particles. The interdependence of the time varying electric and magnetic fields—one producing the other, and vice versa—has allowed researchers to consider them as a single coherent entity: the electromagnetic field. Under this umbrella, students can learn about numerous and varied topics, such as wireless propagation, satellite communications, microwave technology, EM techniques, antennas, and optics, among many others. Fields and Waves in Electromagnetic Communications covers advanced topics in applied electromagnetics for the professional by offering a comprehensive textbook that covers the basics of EM to the most advanced topics such as the classical electron theory of matters, the mechanics model and macroscopic model. Specifically, the book provides a welcome all-in-one source on wireless and guided EM that deals in a wide range of subjects: transmission lines, impedance matching techniques, metallic waveguides, resonators, optical waveguides, optical fibres, antennas, antenna arrays, wireless systems, and electromagnetic compatibility (EMC), and more. The content is supported with innovative pedagogy, the most recent reports and working principles of relevant and contemporary technological developments including applications, specialist software tools, laboratory experiments, and innovative design projects. Fields and Waves in Electromagnetic Communications readers will also find: Multiple practical examples, similes and illustrations of interdisciplinary topics related to wireless and guided electromagnetism Explanations of new topics with support of basic theories connected to real-world contexts and associated applications Sets of technology applications that rely on advanced electromagnetism A series of review questions and drills, end-of-chapter problems, and exercises to help enforce what was learned in each chapter Fields and Waves in Electromagnetic Communications is an ideal textbook for graduate students and senior undergraduates studying telecommunication and wireless communication. It is also a useful resource for industry engineers and members of defense services. Moreover, the book is an excellent non-specialist engineering reference able to be used in other disciplines, such as biomedical engineering, mechatronics, computer science, materials engineering, civil and environmental engineering, physics, network engineering, and wireless services.

Book Description
Field work, supplemented by laboratory studies, is a cornerstone for the geological sciences. This volume provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. One hundred and twenty-three main entries prepared by leading authorities from around the world deal with aspects of exploration surveys, geotechnical engineering, environmental management. field techniques, mapping, prospecting, and mining. Special efforts were made to include topics that consider aspects of environmental geology in particular those subjects that involve field inspections related to, for example, the placement of artificial fills, sediment control in canals and waterways, the geologic effects of cities, or the importance of expansive soils to environmental management and engineering. In addition, some widely ranging topics dealing with legal affairs, geological methodology, the scope and organization of geology, report writing, and other concepts, such as those related to plate tectonics and continental drift, provide a necessary perspective to the arena of field geology.

Book Description
The book provides an elaborate treatment of groundwater prospecting and management covering remote sensing, geological–geophysical cum hydrogeological studies, exploration (geological and geophysical), development (well logging techniques, pump test, its analysis and applications in well design), contamination (pollution of groundwater) and regulatory legislations regarding groundwater utilization under one cover. The book presents an elucidation of fundamental and theoretical background of each technique supported by necessary illustrative examples and exclusive case studies. It is a text-cum-reference book not only for students, research scholars and practicing earth scientists but also for practicing civil and agricultural engineers working in the application of groundwater resources, engaged in its exploration, development, contamination, legislation and management. The general readers can also refer the book for understanding the groundwater domain for adequate knowledge, as groundwater resources are essential life support commodity which is replenishable but not inexhaustible.
