This book is a great source of information regarding the field of hydrogeology primarily intended for the people interested in the fields of earth sciences, environmental sciences, and physical geography. In the past few years, the world has started paying great attention on the area of groundwater hydrology and the inculcation of hydrogeology. It is mainly due to the rising requirement to meet the acute shortage of water, especially the increasing demand of ground water. This book has been written by a number of analysts belonging to different countries. It clearly explains a wide area of problems in the field of hydrogeology. Karst hydrogeology and removal procedures, hydrogeochemistry, soil hydraulic properties as a component influencing groundwater refill procedures, purposeful theoretical structures, and geophysical exploration for groundwater have all been described in this book. It provides the reader with an outlook on the work of hydrogeologists and scientists on the optimization of groundwater resources. This book will prove to be immensely beneficial to graduates and workers of this field.
