The area of groundwater hydrology and the discipline of hydrogeology have appealed a lot of consideration during the past few years. Groundwater recharge and discharge are important—although typically inconspicuous—aspects of the global hydrological cycle. Recharge involves the downward movement and influx of groundwater to an aquifer; discharge involves the upward movement and outfluxes of groundwater from an aquifer. Recharge and discharge activities are usually spatially limited to a small portion of an aquifer. Groundwater recharge and discharge are important aspects of the global hydrological cycle and are critical to the analysis of groundwater flow systems and water budgets.

Groundwater Hydrology integrates selected exploring theoretical and applied aspects of hydrogeologic science, including studies ranging from local areas and short time periods to global problems and geologic time; innovative instrumentation; water-resource and mineral-resource evaluations; and overviews of hydrogeologic systems of interest in various regions. This book clearly demonstrates the extensive range of issues that are dealt with in the field of hydrogeology, giving the reader a global perspective on what hydrogeologists and co-scientists are currently working on to better manage groundwater resources. Transient groundwater flow between a reservoir and a semi-infinite unconfined aquifer has been one of the fundamental research topics in hydrogeology. Prediction of water level changes in the aquifer, due to water level variations in the reservoir, is of importance in contamination control, irrigation and hydrology.

Providing worldwide progress in hydrogeology; this book will be of interest for scientists, researchers, engineers, and practitioners in this field.
