В представленной монографии доктор технических наук, профессор Нижегородского государственного архитектурно-строительного университета, заслуженный геолог РФ А.М. Коломиец подробно излагает разработки эффективных и рациональных технологий при поисках и разведке разнообразных полезных ископаемых.
Groundwater is an invisible but critical component of the hydrologic cycle. It represents the largest source of readily available drinking water on the planet and is therefore an essential resource for humans. Groundwater also provides baseflow to streams and plays a critical role in maintaining the health of freshwater ecosystems. Pressure on groundwater resources is increasing and there is growing evidence that extraction from major aquifers are gradually depleting groundwater reserves worldwide. Predicted climate variability, such as reduced precipitations or increased temperatures, may further exacerbate pressures on groundwater reserves.
After a 20-year hiatus, we are pleased to bring you the 2nd Edition of Fundamentals of Groundwater. Like its predecessor, the book is written at an introductory level to facilitate learning and teaching, while maintaining appropriate rigor. Not surprisingly, much has changed with this edition in terms of its look and feel and importantly the content. Most obvious is the use of color in many figures throughout the book. As the book progressed, the dearth in high-quality colored figures and photographs in traditional journal articles became obvious. Fortunately, here in the United States, groundwater-related documents and reports of the U.S. Geological Survey represent a valuable treasure of high-quality graphical material.
This book has grown from my lecture notes for a ten-week graduate class. It is intended for students and professionals who want to know how to derive some of those familiar equations and formulas in hydrogeology. Demonstrated with numerous examples, the book compiles various means for solving differential equations. All problems in this book have been re-solved, and in many cases new solutions are provided. Step-by-step procedures are given when a method is introduced. Readers of other disciplines may find that the methods presented here are also applicable to their fields of interest.
Water is essential for life. It is required for other uses also such as irrigation, industry, and power development. Its demand is increasing with the increase in population and changes in life style, whereas the availability is practically constant. In India, water is available as precipitation which is concentrated largely in a few months of monsoon season and snowfall in the higher mountains for an equally short time window. Rainfall in monsoon months is also temporally and spatially random.
Traditionally, hydrogeology is defined as the area of geologic sciences, as well as engineering, that in its broadest sense deals with water below the land surface. Hydro is the Greek word for water, and geology is the science of Earth: geo being a prefix derived from the Greek word gaia (meaning the earth, but also Gaia – a primordial Earth goddess in Greek myth), whereas logy is derived from the Greek word logos which means word, thought, principle, or speech, but in modern times is most commonly understood to mean science. Thus, geology literally means the science of Earth.
Characterizing and understanding the variability of hydroclimatological processes and measurements are essential for assessing the performance of water resources infrastructure and its management and for planning successful and efficient water resources projects.
