  • Chemistry of Soil Organic Matter

    • 1 Edición
    • Volumen 17
    • K. Kumada
    • Inglés
    Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid. The author of this book began to study humus at the end of the 1940s and continued until 1984 when he retired from Nagoya University. With the intention of establishing a systematic understanding of soil organic matter, he has compiled facts and a discussion of humus based on his extensive experimental results during the past 40 years.In this book, humic acids are classified into A, B, Rp and P types, based on their optical properties. The elementary composition and other chemical properties of humic acid types are shown to be regularly different from each other. A new method for humus composition analysis applied to various kinds of soils in Japan and several other countries indicates that the diversity of humus compositions of soils is systematically understandable. These findings lead the author to novel theories on the chemical configuration and formation of humic acids and humic substances. Diagenesis of humus under terrestrial conditions is illustrated as to the buried humic horizons of Black soil (Andosol).The book will be useful not only to soil scientists and agronomists but also to geochemists, oceanographers, limnologists, water scientists, biologists and chemists who are dealing with organic matter in terrestrial, aquatic, and sedimentary environments.

  • Carbonate-Clastic Transitions

    • 1 Edición
    • Volumen 42
    • Laurence (Hy) Doyle + 1 más
    • Inglés
    Over the years, the field of sedimentology has become subdivided into various specialities. Two of the largest groups are those who study clastic rocks and those who study carbonates. There is little communication between the two: journals appear which are exclusively devoted to one or the other, and research conferences tend to be mutually exclusive. On the other hand, rocks themselves cannot be "pigeon-holed" in this way - the facies change from clastic to carbonate both laterally and through time. This volume stems from the editors' observations of such changes in the Gulf of Mexico and their realization that these geologically important transitions were being largely ignored because of professional compartmentilization... book opens with a chapter which gives an overview of the whole picture of global patterns of carbonate and clastic sedimentation. It then proceeds to a discussion of sedimentary models of siliciclastic deposits and coral reef relationships. The rest of the book comprises eight case studies on carbonate-clastic transitions, and a final chapter on control of carbonate-clastic sedimentation systems by baroclinic coastal currents.The aim of the book is to emphasize that clastic and carbonate sedimentation are not separate but part of a continuum - a transition which needs to be more thoroughly investigated and better understood. The excellent research papers presented here will undoubtedly help to achieve this goal.

  • Biogeography and Plate Tectonics

    • 1 Edición
    • Volumen 10
    • J.C. Briggs
    • Inglés
    One needs to look at only a small portion of the enormous literature on plate tectonics published in the last 15 years to realize that there are many differences between the various reconstructions that have been presented. It becomes obvious that, although there is a general agreement about the presence of an assembly of continents (a Pangaea) in the early Mesozoic, there is considerable disagreement among earth scientists as to the configurement of the assembly and the manner and timing of the subsequent dispersal. While the revolution in geophysics was taking place, systematic work in paleontology and neontology was being carried out. This book is an attempt to incorporate the biological evidence into the theory of plate tectonics.The author traces the changing relationships among the various biogeographic regions and demonstrates how such changes may often be correlated with the gradual geographic alteration of the earth's surface. He analyses recent information about the distribution of widespread groups of terrestrial and freshwater vertebrates, invertebrates and plants, and discusses the biogeographical effects of the movement of oceanic plates.It is particularly important to obtain dependable information about certain critical times in the history of continental relationships. We need to know when the terrestrial parts of the earth were broken apart and when they were joined together. The present investigation makes it clear that we cannot depend entirely on evidence from plate tectonics nor will purely biological evidence suffice. This book thus provides much of interest to systematists working on contemporary groups of plants and animals, paleontologists, evolutionary biologists, and professors teaching courses in biogeography.

  • Surface Operations in Petroleum Production, I

    • 1 Edición
    • Volumen 19A
    • G.V. Chilingarian + 2 más
    • Inglés
    This is the first part of a two-volume work which comes at a time when oil producers are taking a close look at the economy of oilfield operation and redesign of production technology to improve ultimate recovery. The very high cost, and risk, of the search for new oilfields demands the re-evaluation of production technology and reservoir engineering to improve the production characteristics of existing oilfields.It is the aim of this work that it will be instrumental in the improvement of the global enhancement of oil production and ultimate recovery. It is the outcome of extensive collaboration between experts in petroleum who have devoted their time to the lucid expression of the knowledge that they have acquired through experience in the evaluation and solution of field problems, and development of economic field processes. Oil production companies have been generous in their cooperation through assistance and encouragement to the authors and permission to publish data, designs and photographs.Together... the two books provide a detailed and comprehensive coverage of the subject. The physical and chemical properties of the fluids encountered by engineers in the field are clearly described. The properties, methods of separation, measurement, and transportation of these fluids (gases, condensate liquids derived from natural gas, crude oils and oilfield waters) are dealt with. Following a presentation of the fluids and their process technology, a series of chapters give a thorough discussion of every type of surface equipment that is encountered in the myriad aspects of oilfield operations, ranging from waterflooding to new enhanced oil recovery techniques. Included are all methods for pumping, water control, production logging and corrosion control. The coverage also extends to: well completion and work-over operations, methods for design and operation of underground gas storage, and a review of offshore technology.Surface Operations in Petroleum Production is therefore a comprehensive reference which will be invaluable for field production managers and engineers; as well as being an ideal text on production technology to complement the study of reservoir engineering.

  • The Lightning Discharge

    • Martin A. Uman
    • Inglés
    From the Preface: In the 18 years since my technical monograph Lightning (McGraw-Hill, 1969; Dover, 1984) was first published, there have been significant advances in our understanding of lightning, but, until now, there has been no new monograph on the subject. A number of edited collections of papers and conference proceedings relating to lightning have been published during this period and are listed in Appendix D as well as being referenced, where appropriate, throughout the text... In the present book, the chapters are organized primarily by lightning process. Each chapter contains a reference list of essentially all literature on the subject discussed in that chapter, although all of these references may not be cited in the text.

  • Hydraulic Processes on Alluvial Fans

    • 1 Edición
    • Volumen 31
    • R.H. French
    • Inglés
    Alluvial fans are among the most prominent landscape features in the American Southwest and throughout the semi-arid and arid regions of the world. The importance of developing a qualitative and quantitative understanding of the hydraulic processes which formed, and which continue to modify, these features derives from their rapid and significant development over the past four decades. As unplanned urban sprawl has moved from valley floors onto alluvial fans, the serious damage incurred from infrequent flow events has dramatically increased.This book presents a concise, coherent discussion of our current and rapidly expanding knowledge of hydraulic processes on alluvial fans. It addresses the subject from a multidisciplinary viewpoint, acquainting the geologist with engineering principles, and the civil engineer and planner with geological principles pertinent to the analysis of hydraulic processes on alluvial fans. The book thus provides much of interest to geologists, civil engineers and planners involved in floodplain management and drainage design in arid and semi-arid regions.

  • Microcomputer Programs for Groundwater Studies

    • 1 Edición
    • Volumen 30
    • D. Clarke
    • Inglés
    This book provides the practising hydrogeologist with a selection of microcomputer programs which the author has found to be very useful as an aid in the investigation of groundwater wells and aquifers. The programs are written in BASIC and are designed to suit as wide a range of computer as possible.The book begins with a group of programs which solve several of the most common functions encountered in groundwater science. These are then developed into programs capable of calculating drawdown in a variety of discharge rate/aquifer/boundar... configurations, either at one time, or a series of exponentially increasing times. The author shows how a computerised form of Newtons method (for solving difficult equations) may be applied to such tasks as evaluating storage coefficient if transmissivity is known. Lagrangian interpolation is used to produce accurate values from tabled functions, either within a program, or on demand.One of the major programs in the book may be used to enter discharge test data into a computer, edit it as required (e.g. change drawdown measurements from feet to metres, or water levels to drawdowns etc.), and finally to analyse the data. For example, three different methods are provided for evaluation of the well equation. Another program is provided for controlling a plotter to produce several popular types of discharge test graphs; and a new image well method is included for simulating boundaries consisting of straight line junctions between areas of two different transmissivities.Thi... is a practical book, written to solve real-life problems. Accordingly, program operation is clearly described, but derivation of equations and functions have been omitted. (For those readers wishing to check on derivations, references are provided). Readers familiar with microcomputer programming may apply the programs given here to their own work, perhaps incorporating them as subroutines into large, more specialized programs. Those unfamiliar with programming can use the programs as they are listed. All programs are designed to be run with no more than an occasional reference to the written instructions being necessary.

  • Application of Optimal Control Theory to Enhanced Oil Recovery

    • 1 Edición
    • Volumen 21
    • W. Fred Ramirez
    • Inglés
    In recent years, enhanced oil recovery techniques have received much attention in the oil industry. Enhanced oil recovery methods can be divided into three major categories: thermal processes which include steam flooding, steam stimulation, and in-situ combustion; chemical processes which include surfactant-polymer injection, polymer flooding, and caustic flooding; and miscible displacement processes which include miscible hydrocarbon displacement, carbon dioxide injection of large amounts of rather expensive fluids into oil bearing reservoir formations. Commercial application of any enhanced oil recovery process relies upon economic projections that show a decent return on the investment. Because of high chemical costs, it is important to optimize enhanced oil recovery processes to provide the greatest recovery at the lowest chemical injection cost.The aim of this book is to develop an optimal control theory for the determination of operating strategies that maximize the economic attractiveness of enhanced oil recovery processes. The determination of optimal control histories or operating strategies is one of the key elements in the successful usage of new enhanced oil recovery techniques. The information contained in the book will therefore be both interesting and useful to all those working in petroleum engineering, petroleum management and chemical engineering.

  • Reservoir Sedimentation

    • 1 Edición
    • Volumen 29
    • G.W. Annandale
    • Inglés
    Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

  • Water Resources and Water Management

    • 1 Edición
    • Volumen 28
    • M.K. Jermar
    • Inglés
    The size and number of water projects and other development activities which influence the hydrological cycle have reached such proportions that the majority of problems involved extend beyond the boundaries of the traditional disciplines of hydraulics, hydrochemistry, hydrology and hydrogeology.New scientific methods for the solution of the contemporary problems in water management include analogy, operation research, system analysis and cybernetics. The distinctive features of these methods are their emphasis on measurement and on the use of conceptual models described in quantitative terms, the verification of their theoretical predictions, and their awareness that concepts are conditional and subject to growth and continuous change. This new approach should be defined within the framework of water resources management, i.e. within a complex of activities whose objective is the optimum utilization of water resources with regard to their quality and availability and the requirements of society. These water management activities should at the same time also ensure an optimum living environment, above all through protection of water resources against deterioration and exhaustion as well as through the protection of society against the harmful effects of water. In the course of these activities water resources management should avail itself of the entire spectrum of explicit sciences, gradually coming to form the sphere of its own theory.This monograph deals with the fundamental interdisciplinary problems of this complex sphere, an understanding of which is indispensable for successful water resources management in the widest sense of its social functions and environmental consequences. Thus, a common basis is provided for the mutual understanding of specialists from different backgrounds.

  • Biogeochemical Processes at the Land-Sea Boundary

    • 1 Edición
    • Volumen 43
    • P. Lasserre + 1 más
    • Inglés
    There is an intuitive belief among scientists that each estuary or lagoon is unique and different. Similarities do exist, however, and this book attempts to highlight some common properties and perhaps some innovative views on biogeochemical processes, and biological fluxes which are of central concern in the understanding of the land-sea boundary. The contents are based upon lectures given at a Seminar organised as the scientific component of the 17th General Meeting of SCOR, held at the Station Biologique de Roscoff, France, on 22-24 October 1984. The original lectures have been substantially extended and revised in order to give a fuller treatment of the subject. The contributions identify important processes influencing (I) Behaviour of chemical species, (II) Nutrient cycling and mechanisms of organic transformations and (III) Uptake of trace elements by living systems. The connection between terrestrial and oceanic systems is a functional one and the consequences of this linkage on the very large variety of coastal systems are profound. It is widely recognized that many of the major processes which influence the biological properties and chemical forms of elements, and their biogeochemical cycles in the ocean occur at the land-sea boundary, especially in estuaries, coastal lagoons, the coastline and the shelf. Over 80% of living systems and their fisheries take place in near shore waters and the consequential production of organic matter produced triggers off the high level of activity. Over the last fifteen years, there has been considerable stimulus to provide framework to evaluate the interactions and effects of human activities. The rich assemblage of tables and figures and of literature citations contained in the chapters provides an excellent basis for in-depth investigations.Ocean... limnologists, aquatic chemists, marine biologists, and environmental specialists will find this book highly valuable reading for advanced research and training purposes.

  • Marine Mineral Exploration

    • 1 Edición
    • Volumen 41
    • H. Kunzendorf
    • Inglés
    The past 20 years have seen extensive marine exploration work by the major industrialized countries. Studies have, in part, been concentrated on Pacific manganese nodule occurrences and on massive sulfides on mid-oceanic ridges. An international jurisdictional framework of the sea-bed mineral resources was negotiated by the United Nations Conference on the Law of the Sea (UNCLOS III). A most important outcome of this conference was the establishment of an Exclusive Economic Zone (EEZ) of at least 200 nautical miles for all coastal states and the recognition of a deep-sea regime.Mineral deposits in EEZ areas are fairly unknown; many areas need detailed mapping and mineral exploration, and the majority of coastal or island states with large EEZ areas have little experience in exploration for marine hard minerals. This book describes the systematic steps in marine mineral exploration. Such exploration requires knowledge of mineral deposits and models of their formation, of geophysical and geochemical exploration methods, and of data evaluation and interpretation methods. These topics are described in detail by an international group of authors. A short description is also given of marine research vessels, evaluation of marine exploration examples; and an overview is provided of the jurisdictional situation after UNCLOS III.

  • Kinematic Hydrology and Modelling

    • 1 Edición
    • Volumen 26
    • M.E. Meadows + 1 más
    • Inglés
    Requiring little mathematical background, the book provides tools for hydraulic engineers and hydrologists concerned with estimating catchment runoff and floods. It condenses widely spread research literature on the subject of kinematic hydrology and emphasizes basic principles so it should be of value to students and teachers in these areas. The book is comprehensive and yet written in a basic way enabling practitioners to pick out relevant sections and apply them to real problems. It also contains a valuable collection of charts and equations as well as simple computer programs for modelling catchment runoff and stream flow using the kinematic equations.A wide spectrum of hydrological processes can be analyzed using the kinematic equations. Overland flow, stream flow and even groundwater flow can be studied. A review of the assumptions behind the theory indicates where alternative equations are more accurate. The book thus provides tools for hydrological simulation, stormwater system design and catchment management. It will be particularly useful for professors and students in postgraduate and senior years in hydrology, and practicing engineers and hydrologists in stormwater, flood and water resources fields.

  • Groundwater Modelling

    An Introduction with Sample Programs in BASIC
    • 1 Edición
    • Volumen 25
    • W. Kinzelbach
    • Inglés
    With the growing concern about groundwater resources both with respect to quantity and quality, the need for groundwater modelling tools is increasing. Although there are a number of excellent introductions to the concepts of groundwater flow and pollution transport, the student or practising engineer wishing to develop a model and do practical work on the computer finds that there is still a gap between the understanding of concepts and the ability to handle the actual computations. A great deal of groundwater modelling software for personal computers and microcomputers has appeared recently, but taking these models from the shelf and applying them without a background on their capabilities often leads to disappointment and frustration. This book provides the reader with all necessary details to start modelling on his own. It gives a comprehensive introduction to the major techniques currently used in the modelling of groundwater flow and pollutant transport in groundwater. Both self-contained and comprehensive, it presents a wide variety of methods currently applied in the management, protection, and remediation of groundwater resources, which allows the reader to take the step from understanding the concepts to the ability to handle actual computations. All major techniques are illustrated by a total of 19 sample programs in BASIC which can be modified by the reader to suit his own need. The programs can be run directly on an Apple II+ or compatible personal computer, and with slight modifications, most can be transferred to other microcomputers with BASIC capability and at least 48K of central memory. The necessary modifications for running the programs on an IBM-PC are indicated in the appendix.Students and professionals in the fields of hydrogeology and civil and environmental engineering will find this to be an extremely useful book. Knowledge of the basic concepts of hydrogeology is assumed and, starting from that basis, the book will enable them to understand mathematical groundwater models and write computer programs of their own.

  • Soil Physics with BASIC

    Transport Models for Soil-Plant Systems
    • 1 Edición
    • Volumen 14
    • G.S. Campbell
    • Inglés
    This book covers material taught in a graduate-level soil physics course at Washington State University. While most soil physics courses dwell mainly on deriving rather than solving the differential equations for transport, the author's approach is to focus on solutions. Graduate students in agricultural and biological sciences usually have a good working knowledge of algebra and calculus, but not of differential equations. In order to teach methods for solving very difficult differential equations with difficult boundary conditions using fairly simple mathematical tools, the author uses numerical procedures on microcomputers to solve the differential equations. Numerical methods convert differential equations into algebraic equations which can be solved using conventional methods of linear algebra.This book reflects the philosophy used in the course. Each chapter introduces soil physics concepts, generally in the conventional way. Most chapters then go on to develop simple computer programs to solve the equations and illustrate the points made in the discussion. Problems at the end of each chapter help the reader practice using the concepts introduced in the chapter. The problems and computer programs are an integral part of the presentation, and readers are strongly encouraged to experiment with each model until both the working of the model and the concepts it teaches are familiar. Although the programs are generally short and relatively simple, they are suitable for use as submodels in large, general-purpose models of the soil-plant-atmospher... system, and have been used in this way by the author and by several of his students.Teachers and students alike will welcome this new textbook. It will enable graduate students to understand and solve transport problems which exist in field situations, and will provide them with a good working knowledge of soil physics - fundamental to so many other areas in soil, plant and engineering sciences.

  • Geology in Petroleum Production

    • 1 Edición
    • Volumen 20
    • A.J. Dikkers
    • Inglés
    A practical book for geologists involved in petroleum production, here is a comprehensive review of basic techniques in production geology, the links with related subjects, and the function of geologists in the planning and operation of all phases of oilfield development. The first part discusses the basic techniques used in the analysis and graphic representation of the stratigraphy, tectonic structure, reservoir sedimentology and hydrocarbon distribution of an oilfield. The second part describes how this knowledge is applied in the various phases of field development. The mutual support between production geology and neighbouring disciplines such as seismology, log interpretation, reservoir engineering is stressed. Throughout the book, the text is secondary to the illustrations; these are examples, mostly hypothetical, of conditions and techniques discussed, designed so as to bring out as clearly as possible the importance of the points made. It is thus an ideal book for graduate students, specializing in petroleum geology and for participants in post-graduate courses, in universities or within industry.

    • Inglés
    This book is addressed primarily to civil engineers familiar with such traditional topics as strength of materials, soil mechanics, and theory of elasticity and structures, but less familiar with the modern development of the mathematical theory of soil plasticity necessary to any engineer working under the general heading of nonlinear analysis of soil-structure system. This book will satisfy his needs in the case of the soil medium.It introduces the reader to the theory of soil plasticity and its numerical implementation into computer programs. The theory and method of computer implementation presented here are appropriate for solving nonlinear static dynamic problems in soil mechanics and are applicable for finite difference and finite element computer codes. A sample computer model subroutine is developed and this is used to study some typical soil mechanics problems.With its comprehensive coverage and simple, concise presentation, the book will undoubtedly prove to be very useful for consulting engineers, research and graduate students in geotechnical engineering.

    After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters.Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed. It also provides a reference for analytical formulae and calculated force forces. It will be of interest to universities and colleges worldwide which have Agricultural Engineering Programs, Civil and Mechanical Engineering schools which specialize in soil mechanics and construction machinery as well as to research stations worldwide with interests in soil tillage, soil physics etc.

  • Groundwater Monitoring Handbook for Coal and Oil Shale Development

    • 1 Edición
    • Volumen 24
    • L.G. Everett
    • Inglés
    Standing alone as the main authority on the subject, this handbook is the result of a multi-million dollar investigation into groundwater monitoring strategies at energy extraction sites. It gives a detailed, step-by-step description of a proven groundwater monitoring methodology which can be used at all potential pollution sites. This methodology, developed by the author and a ``blue ribbon'' team of hydrologists and hydrogeologists from all over the United States, is endorsed by the U.S. Environmental Protection Agency as ``establishing the state-of-the-art used by industry today''.Although site-specific data are provided, the handbook is developed for general application to coal and oil shale development. All sources of potential groundwater contamination from these two energy extraction types are identified as part of the overall monitoring strategy. Sampling methods are presented, including well design, monitor well placement, sample collection methods, sampling frequency, sample preservation and handling, selection and preservation of constituents for monitoring, sample analysis, and interpretation of water quality data. A complete review is provided of drill stem steps, dual packer tests, long term pump tests, and single packer tests. In addition, hydraulic methods, the application of geophysical techniques including temperature, caliper, gamma ray, spinner, radioactive tracer, velocity, sonic, density, electric, and seisviewer logs are presented. The use of a chronological series of steps, each being fully developed and extensively referenced, means that it is particularly easy to follow for the reader wishing to establish a groundwater monitoring program at a coal or oil shale site. One of the great advantages of the handbook is that it is very detailed, with actual data provided.The handbook is a must for consulting engineers, coal and oil development companies, government and private environmental groups, institutes and universities involved in pollution studies. It will also undoubtedly be used to good advantage by teachers and students for many different types of courses including geological engineering, coal and oil shale mining, environmental geology, sanitary engineering, hydrogeology, etc.

    Oceans play a pivotal role in our weather and climate. Ocean-borne commerce is vital to our increasingly close-knit global community. Yet we do not fully understand the intricate details of how they function, how they interact with the atmosphere, and what the limits are to their biological productivity and their tolerance to wastes. While satellites are helping us to fill in the gaps, numerical ocean models are playing an important role in increasing our ability to comprehend oceanic processes, monitor the current state of the oceans, and to a limited extent, even predict their future state.Numerical Models of Oceans and Oceanic Processes is a survey of the current state of knowledge in this field. It brings together a discussion of salient oceanic dynamics and processes, numerical solution methods, and ocean models to provide a comprehensive treatment of the topic. Starting with elementary concepts in ocean dynamics, it deals with equatorial, mid-latitude, high latitude, and coastal dynamics from the perspective of a modeler. A comprehensive and up-to-date chapter on tides is also included. This is followed by a discussion of different kinds of numerical ocean models and the pre- and post-processing requirements and techniques. Air-sea and ice-ocean coupled models are described, as well as data assimilation and nowcast/forecasts. Comprehensive appendices on wavelet transforms and empirical orthogonal functions are also included.This comprehensive and up-to-date survey of the field should be of interest to oceanographers, atmospheric scientists, and climatologists. While some prior knowledge of oceans and numerical modeling is helpful, the book includes an overview of enough elementary material so that along with its companion volume, Small Scale Processes in Geophysical Flows, it should be useful to both students new to the field and practicing professionals.

  • Enhanced Oil Recovery, I

    An in-depth study of the fundamental aspects of enhanced oil recovery (EOR), this book brings together detailed analyses of proven techniques. It begins with the current theories of the origin of oil and ends with a treatise on waterflooding which is the basis of the majority of EOR processes. Two and three-phase relative permeability relationships are discussed since they form the basis for fluid flow processes in porous media. The advent of EOR has increased the need for a better understanding of three-phase flow because this has become an integral part of carbon dioxide and steam injection, yet is an area of experimental study that has been seriously neglected. The book gives a complete review and theoretical analysis of two- and three-phase fluid flow, plus a basic introduction to single-well pressure transient testing which is essential to the evaluation of volume, intrinsic reservoir pressure, reservoir discontinuities, in situ permeability and many other data required for complete reservoir evaluation. A discussion of oilfield waters is followed closely by the chemical and physical properties of employing various current EOR techniques.The book will interest a wide range of readers. Teachers of petroleum engineering will find it a ready reference to basic requirements for implementation of various EOR processes. Petroleum engineering researchers can use it to review the current state-of-the-art of the basic premise of EOR and find in it the necessary background analyses for projection of future research. The field-oriented, practical petroleum engineer will discover it to be a reliable reference to criteria for pre-EOR reservoir analysis.

  • Hydrology of the Nile Basin

    A wealth of hydrological, hydrometeorological, hydrometrical and other related data covering nearly all parts of the Nile Basin is presented in this volume. After an introductory chapter on the Nile's history, chapters cover: the physiography, topography, and climate of the different parts of the Nile Basin; rainfall on the Basin, evaporation from open surfaces, and evapotranspiration from cropped areas. Rainfall data for a 30-year period from 1938 to 1967 are summarized and analyzed; evaporation and evapotranspiration measurements are presented, analyzed and discussed. In the absence of actual measurements, attempts have been made to estimate them from a number of formulae using the available climatological normals. The results obtained are important for planning, design and management of water supply and control projects, especially for irrigation and drainage. The geology of the Nile Basin is briefly reviewed and its effect on groundwater potentials, quality and quantity is discussed. Surface runoff and discharge at the key stations is covered, and an extensive review given of existing water storage, control and conservation projects in the Nile Basin.Thus the volume contains an enormous amount of data that will be of great practical value to consulting engineers. It is a book which should be in the library of all hydrological institutes and universities.

  • Streamflow Characteristics

    • Inglés
    Reliable estimates of streamflow characteristics are needed for planning, design, and operation of works for providing water supplies and for protection from flooding. This book brings together some of the most useful estimation methods - those that are simple, practical, and require only commonly available or readily obtainable data, and which give results comparable in accuracy with those derived from more sophisticated methods. The author describes how streamflow data are collected, how the characteristics are computed, how they are changed by man's activities, and how they are used in planning and design. Chapters describing statistical principles and techniques, and the effects of various climatic and physiographic factors on streamflow are included. The analytical methods are described in sufficient detail that the reader can apply them to his data. Further applications and other techniques are referred to in bibliographies.
