Hydrogeology is the study of occurrence, distribution and movement of groundwater. Groundwater contamination, conservation of supplies and water quality are the key concerns under hydrogeology. It deals with the flow of water through aquifers and other shallow porous media. The prediction of the behavior of an aquatic system with the help of an analysis of past and present observations is the primary goal of hydrogeology. It also studies the hydraulic conductivity, porosity and transmissivity of aquifers. The advancements in topographical mapping are also playing a crucial role in enhancing groundwater sustainability. From theories to research to practical applications, case studies related to all contemporary topics of relevance to hydrogeology have been included in this book. The topics included herein are of utmost significance and bound to provide incredible insights to readers. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
