Groundwater Hydrology

0.0

This book presents a comprehensive discussion of basics of groundwater hydrology, its hydrologic and engineering aspects, and the mechanics involved in the study of flow of groundwater. The matter is presented in a logical sequence, placing emphasis on the application of theory and on the practical aspects of groundwater hydrology. The book introduces the geological formations of aquifers, discusses soil physics, describes the solutions of differential equations for confined and unconfined aquifers, elucidates groundwater flow equations and explains the phenomenon of interference of wells. The book also deals with tube wells and open wells, their design criteria, construction and work, revitalization and spacing, as well as their potential for irrigation. The issues of groundwater prospecting, analog models to study the response of aquifers to simulated field conditions, the current issues of concern pertaining to quality parameters of groundwater, and applications of remote sensing for survey and geological explorations for groundwater, are all addressed in the latter part of the book. The book is intended for the senior undergraduate students of civil engineering and postgraduate students (who specialize in Water Resources Engineering) of civil engineering. Besides it will be useful to the students pursuing courses in agricultural engineering. Salient Features Includes numerous objective-type questions (with answers) at the end of each chapter Contains worked-out numerical problems Provides chapter-end questions and unsolved numerical problems with answers for practice by students About the Author V. C. Agarwal PhD (Hydraulic Engineering), is currently Professor and Head, Department of Civil Engineering, Shepherd School of Engineering and Technology, SHIATS, Naini, Allahabad. Prior to retirement, he taught the subjects of fluid mechanics, fluid power and open channel flow to undergraduate and postgraduate students for over 39 years. He also held several administrative positions during his active career. His areas of research included hydraulic engineering and capsule transportation (a third-generation pipeline). He has presented/published 50 research papers in national and international conferences and journals of repute. He also developed a fluid mechanics laboratory and established many new experiments.
