This book focuses on the study of groundwater flow problems as well as a thorough analysis of real practical field case studies in order to develop an understanding of the interaction between the inputs, outputs and internal flow processes. The book begins by quantifying the components and parameters of the conceptual models before considering the selection of appropriate mathematical models. The book covers a range of themes, theoretical basis of groundwater hydrology including recent developments, collection and interpretation of field data leading to the development of conceptual models, analytical solutions and introduces a wide variety of numerical techniques for groundwater investigations.
