The hydrogeoplgy of a specific region is primarily shaped by three factors: geology, geomorphology and climate. These elements determine the unique characteristics of the groundwater system is that area. To understand and evaluate these hydrogeological features, several key properties are taken into account. Porosity, yield and hydraulic conductivity are the main properties used to describe and analyze the catchments. Porosity refers to the amount of empty space or voids within the rocks or soil where water can be stored. Yield is the measure of the amount of water that can be extracted from a particular aquifer of geological formation.This book covers a wide range of topics, including the sources and reservoirs of groundwater, fluid flow dynamics and the physical and chemical composition of groundwater. Additionally, it offers insights into the economic significance of groundwater and its exploitation and use. This book will serve to earth science professionals involved in groundwater exploitation, as well as geotechnical engineers. It is relevant to scientists, researchers and practitioners in both developing and industrialized countries, making it a valuable reference for anyone interested in the field of hydrogeology.
