内容説明 ?Natural Groundwater Flow? is an important volume focused on providing a complete description of groundwater flow velocity field and the velocity oriented approach for conducting numerical simulations and other applications. The book presents background information regarding the causes leading to spatial variations of the water table， related concepts of phreatic and specific storage， artificial flow， and flow driven by differences in groundwater density.Block-scale permeability is discussed in detail， and numerical applications using the Galerkin finite element method and pre-modeling techniques for obtaining data required for numerical modeling are examined. The book also presents never-before-published information regarding the theoretical justification and elucidation of hydrological systems analysis to analyze the effects of different spatio-temporal scales. ?Natural Groundwater Flow? is an important reference for environmental physicists， hydrogeologists， civil engineers， mathematical geologists， and petroleum reservoir engineers.
