Hydrodynamics of Time-Periodic Groundwater Flow introduces the emerging topic of periodic fluctuations in groundwater. While classical hydrology has often focused on steady flow conditions, many systems display periodic behavior due to tidal, seasonal, annual, and human influences. Describing and quantifying subsurface hydraulic responses to these influences may be challenging to those who are unfamiliar with periodically forced groundwater systems. The goal of this volume is to present a clear and accessible mathematical introduction to the basic and advanced theory of time-periodic groundwater flow, which is essential for developing a comprehensive knowledge of groundwater hydraulics and groundwater hydrology. Volume highlights include: Overview of time-periodic forcing of groundwater systems Definition of the Boundary Value Problem for harmonic systems in space and time Examples of 1-, 2-, and 3-dimensional flow in various media Attenuation, delay, and gradients, stationary points and flow stagnation Wave propagation and energy transport Hydrodynamics of Time-Periodic Groundwater Flow presents numerous examples and exercises to reinforce the essential elements of the theoretical development, and thus is eminently well suited for self-directed study by undergraduate and graduate students. This volume will be a valuable resource for professionals in Earth and environmental sciences who develop groundwater models., including in the fields of groundwater hydrology, soil physics, hydrogeology, geoscience, geophysics, and geochemistry. Time-periodic phenomena are also encountered in fields other than groundwater flow, such as electronics, heat transport, and chemical diffusion. Thus, students and professionals in the field of chemistry, electronic engineering, and physics will also find this book useful.

Groundwater hydrodynamics is an emerging subdiscipline in the mechanics of fluids in porous media whose objective is to investigate the invariant geometric properties of subsurface flow and transport processes. Hydrodynamics of Time-Periodic Groundwater Flow covers the understanding of the mechanism of fluid flow in fractured formations through the mathematical modeling of time-periodic groundwater flow, which is essential for developing a comprehensive knowledge of groundwater hydraulics and groundwater hydrology. The main aim of the work is to create a scientific material, which helps the everyday practical designing and with this there is an opportunity to explore and forecast the expectable effect of the underground obstacles, to estimate its order of magnitude and to decide about the necessity of further working sessions. This volume will be of valued resource for students and practitioners as well as professionals in Earth and environmental sciences who deal with groundwater models, groundwater hydrology, soil physics, hydrogeology, geoscience, geophysics, and geochemistry. It will also help local council or government agencies to plan and manage water resources by providing good understanding of groundwater flux exchange for target interventions to improve current best management practices to reduce nutrients export from land to waterway, and how drain can contribute to the water balance of alluvial aquifers over seasonal change that was previously poorly understood. The book will provide conceptual model combined with subsequent quantitative analysis in the aim of improving current numerical models capabilities to simulate the interaction and for the benefit of drainage designing.
