Water Resources And Water Management

by M.K. Jermar

58,29€ + 10% CARD

 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.

Reservoir Sedimentation

by G.W. Annandale

58,29€ + 10% CARD

 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.

Statistical Aspects Of Water Quality Monitoring

145,75€ + 10% CARD

 This volume contains selected papers from the ``Workshop on the Statistical Aspects of Water Quality Monitoring'', held on October 7-10 1985, at the National Water Research Institute in Burlington, Ontario, Canada. The prime objective of the Workshop was to generate interaction between the statistical community and scientists working in the area of Water Quality Monitoring. To this end, topics covered in this Workshop fall into two categories: (1) Methods Development, and (2) the Imaginative Application of Existing Methodologies. Subjects covered include: Time Series, Estimation of Loading, Clustering, Model Development, Censoring Data Analysis, Quality Control and Data Acquisition.In the area of environmental sciences, statistical applications are still in their infancy, with few attempts to systematically develop techniques dealing with environmental issues. The publication of this book is one step towards identifying appropriate statistical techniques and diagnosing problems in Water Quality Monitoring which require new statistical methodologies. The papers presented in this volume represent international expertise, consolidating detailed information on both conventional and new methods.

Groundwater Monitoring Handbook For Coal And Oil Shale Development

by L.G. Everett

58,29€ + 10% CARD

 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.

Microcomputer Programs For Groundwater Studies

by D. Clarke

58,29€ + 10% CARD

 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/boundary 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.This 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.

Hydraulic Processes On Alluvial Fans

by R.H. French

58,29€ + 10% CARD

 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.

Water Resources Development In Developing Countries

by D.J. Stephenson e M.S. Peterson

58,29€ + 10% CARD

 Water resources exploitation has been regarded as a way of initiating economic development in many countries. Planning concepts are now changing. Thorough environmental studies, sociological and economic studies now preceed project formulation. Justification solely on the basis of benefit cost studies is no longer sufficient for many development agencies. The broader approach is introduced in this book, but the real emphasis is on the situation in and needs of developing countries.Some of the problems experienced in building water resources in developing countries are described in this book, and methods of solution based on the limited experience of the authors, are offered. These range from use of unbiased common sense, coupled with a close understanding of people's requirements, to a comprehensive computer simulated planning model. Some types of water resources development are described in more detail. These include irrigation, hydro electric power and rural water supply. Sections on socio-economics and human resource development are also included, as well as on data collection, and project planning. Lessons from the failure of multimillion dollar projects are not hard to come by, and examples and pointers which will assist future planners are given. Attention is paid to the need for aid to include training and to stimulate local economies. However big water projects appear, they cannot escape the effects of the rest of the country's economy. Attention is also drawn to environmental problems, particularly soil erosion, often caused by water resources development. The fact that water resources development cannot be carried out by engineers only, is recognized. The input of many professions, and vast experience, is needed. Drawn on international case studies, much of the material has been presented in postgraduate courses by the authors.

Analysis Of Water Resource Systems

by L. Votruba

58,29€ + 10% CARD

 Water resource systems research provides a basis for rational water management in large basins. The design and operation of water resource systems are both the most complicated and the most important tasks of water management. This book deals with the basic issues involved in the application of systems sciences to water management.A survey of the systems sciences (the general systems theory, cybernetics, systems engineering, operations research and systems analysis) is presented, as well as the methods for water resource systems analysis and for water resource systems analysis and for their evaluation. The mathematical methods used in systems theory have been given detailed treatment. Linear and dynamic programming have been used as models of optimal programming. Since many practical tasks require the simulation models of water resource systems, apart from their principles and a detailed description, the simulation language for computing programming has been included. Other methods of operations research and their application to water resource systems have been analysed and evaluated. Some of these are: models of inventory theory, models of queuing theory, graphs, network analysis, and some special methods like the out-of-kilter algorithm, the chance-constrained model and the chance-constrained model combined with the simluation model. One chapter is devoted to information and information systems in water management. The final part of the book deals with prospects for water resource systems development.The book is intended for engineers and decision-makers involved in projects, operation and research. However, it can be used by students in high schools, technical universities and by graduate students. It will serve as an up-to-date source of information about the principles and methodology of water resource analysis and design.
