Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: There has long been interest in the flow of fluids through permeable aqui fers. Stratigraphic trapping of oil and gas by permeability changes in an aquifer and the amounts of hydrocarbons so trapped are major concerns to the oil industry. The variations of aquifer width and geometry and of the positions in an aquifer where hydrocarbons can be trapped by hydro dynamic forces are intimately intertwined in determining the shape, and thus the volume, of hydrocarbons. Perhaps the seminal work in this area is reflected by King Hubbert's massive review paper "Entrapment of Petroleum under Hydrodynamic Conditions" (Am. Assoc. Pet. Geol. Bull. 37(8), 1954-2026, 1953), in which a wide variety of effects, such as capillarity, buoyancy, surface tension, and salinity of water, are incorporated as basic factors influenc ing the positioning and shaping of hydrocarbon masses in hydrodynami cally active aquifers. In those days, while the basic physics could readily be appreciated, development of a detailed quantitative understanding of the interplay of the various factors in controlling or modulating hydro dynamic shapes was severely limited by computer abilities. Indeed, Hub bert actually constructed and photographed physical models, using alcohol and water, to illustrate basic concepts. It is difficult to obtain an appreciation of the behavior of flow geometries from such experiments when all factors are permitted to vary simultaneously.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Hydrodynamics of Gravity driven Flow Systems in Sedimentary Basins written by Rainer Klaus Senger and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydrodynamics of a mature sedimentary basin affected by uplift, deposition, and erosion is examined in the Palo Duro Basin, Texas, with a cross-sectional ground-water flow model. Transient simulations of ground-water flow assuming uniform fluid density are used to describe hydrodynamic conditions arising from changes in topography. Modeling shows that uplift and tilting of the basin (10 to 15 m.y. ago) caused significant increase in ground-water flow rates. Erosion of the Pecos River valley and the more recent westward retreat of the Caprock Escarpment cause significant hydraulic-head changes in deep aquifer units within the last few million years. Buoyancy effects on regional ground-water flow through the Palo Duro Basin where densities range between 1.00 and 1.15 g/cm3 are studied using a new modeling technique, based on equivalent fresh-water heads and stream functions, incorporating fluid densities that vary in space but are assumed to be time invariant. Flow velocities based on the stream-function solution were found to be more accurate than those based on the head solution, allowing a more accurate interpretation of local flow patterns. Simulated streamlines show that the regional groundwater flow in the vertical plane is not significantly affected by density variations, indicating that the topographically-driven flow component dominates potential buoyancy phenomena. However, equivalent freshwater heads differ from those obtained assuming fresh-water density, which has important implications on model calibration. Paleohydrologic modeling indicates that prior to basin uplift, when the topographically induced head gradients were smaller than at present, buoyancy phenomena can produce stationary convection cells in the western part of the basin, characterized by stratified density distribution. Another convection cell is simulated in the eastern part, where density within the deep aquifer decreases with depth creating thermohaline convection. Potential effects of regional ground-water flow on thermal regime, suggested by the thermal gradient pattern, were studied by simulating energy transport associated with heat flow from the basement and advection through ground water. Simulation results suggest that the thermal regime is dominated by conduction. Advection is probably insignificant due to large anisotropy of the hydrostratigraphic units, relatively shallow depth of the flow system, and large ratio of basin width to basin depth.

Available in PDF, EPUB and Kindle. Book excerpt: Water at the Surface of the Earth: An Introduction to Ecosystem Hydrodynamics provides an introduction to the ways in which biological, physical, cultural, and urban systems at the surface of the earth operate, with a particular focus on the hydrodynamics of ecosystems, i.e., water and its association with other forms of matter, including pollutants, and with several forms of energy. The chapter sequence in this book follows the downward progress of water from the lower atmosphere, through ecosystems at the earth's surface, through the soil and mantle rock, to the ""waters under the earth."" In other words, the book begins with input of water to ecosystems, then describes how it is processed in these systems, and ends with the liquid water yield from them. The book first discusses storms in the atmosphere. These are systems that convert inflows of water vapor into outflows of raindrops and snowflakes that are precipitated to the underlying surface. This is followed by separate chapters on how water is delivered from the atmosphere to surface ecosystems; water budgets at the surface and in the soil; evaporation from these systems back to the atmosphere; water in the local air and rocks; and horizontal movement of water transformed by ecosystems where the preceding storages and fluxes were located.

Book excerpt: Basic Hydrodynamics explores the application of computers to problem solving involved in fluid flow. This book contains 5 chapters that cover the use of BASIC programming language in hydrodynamic problems and some programs with graphic output, as well as some simple finite difference, finite element and boundary element programs. After a brief introduction to BASIC programming, this book goes discussing the fundamentals of potential flow theory that will be used to calculate flows, which can be regarded as frictionless. These topics are followed by a presentation of some analytical expressions for potential flows. Chapter 3 outlines the computer based methods for solving problems within these flows, while Chapter 4 highlights some potential flow methods to the solution of groundwater flows. Exact solutions are also provided for comparison with the computer methods. Lastly, Chapter 5 considers free surface flows, such as linear waves and flows from jets. This work will be of value to engineers, designers, and computer programmers and scientists who are interested in computer application to hydrodynamics field.

Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide for accurate state-of-the-art modelling of free surface flows Understanding the dynamics of free surface flows is the starting point of many environmental studies, impact studies, and waterworks design. Typical applications, once the flows are known, are water quality, dam impact and safety, pollutant control, and sediment transport. These studies used to be done in the past with scale models, but these are now being replaced by numerical simulation performed by software suites called “hydro-informatic systems”. The Telemac system is the leading software package worldwide, and has been developed by Electricité de France and Jean-Michel Hervouet, who is the head and main developer of the Telemac project. Written by a leading authority on Computational Fluid Dynamics, the book aims to provide environmentalists, hydrologists, and engineers using hydro-informatic systems such as Telemac and the finite element method, with the knowledge of the basic principles, capabilities, different hypotheses, and limitations. In particular this book: presents the theory for understanding hydrodynamics through an extensive array of case studies such as tides, tsunamis, storm surges, floods, bores, dam break flood waves, density driven currents, hydraulic jumps, making this a principal reference on the topic gives a detailed examination and analysis of the notorious Malpasset dam failure includes a coherent description of finite elements in shallow water delivers a significant treatment of the state-of-the-art flow modelling techniques using Telemac, developed by Electricité de France provides the fundamental physics and theory of free surface flows to be utilised by courses on environmental flows Hydrodynamics of Free Surface Flows is essential reading for those involved in computational fluid dynamics and environmental impact assessments, as well as hydrologists, and bridge, coastal and dam engineers. Guiding readers from fundamental theory to the more advanced topics in the application of the finite element method and the Telemac System, this book is a key reference for a broad audience of students, lecturers, researchers and consultants, right through to the community of users of hydro-informatics systems.
