The process of integration, in the broadest sense, has been a characteristic feature
of the development of politics, economics and specific economic and technological
fields in the last thirty years. The greater the necessity for relationships befween
functionally interdependent elements, and the more easily these relationships can
be realized, the sooner have systems been formed from these elements. The large-scale
systems developed in economics, energetics, transportation, and, since the sixties,
water management, require a qualitatively new approach and treatment.
The modern engineer, now and in the future, has to supplement individual reasoning
and creative work with a scientific approach to engineering tasks. Basically, the research-
scientist investigates and explains existing natural phenomena and the relationships
between them; the engineer creates something which is new and which
will become useful. Their activities mutually influence each other. In earlier times
engineering was more closely related to art, since engineering and art have the
element of creation in common; now engineering is closer to science.
In accordance with social needs, the research scientist is trained to demonstrate
theoretically the possibility of constructing a technical creations as a new, not yet
existing, reality and to bring it into existence. The classification of creative work
in applied research and development as scientific activity can be adopted without
hesitation. The relationship sciencdevelopment-implementation conceives of
science as an integral part of production.
If issues of water resource systems are to be treated at the contemporary level of
scientific knowledge, the appropriate, related scientific fields, such as systems analysis,
the probability theory, operations research etc. need to be understood.
The aim of this book, which deals with water management, is to present the basic
facts on complex water resource systems using the systems approach. Since no final
interpretation of the basic terms and concepts is available, they have been defined
in relation to another application of systems science, namely economics.
The fundamentals of the new, related scientific disciplines, the results of which
are used in complex water resource systems, have been included in the book to facilitate
reading and reduce the number of necessary reference books.The references
included in this book are intended for further study. The examples serve to show the
application of the general theory. Knowledge of the elements of theory of probability,
mathematical statistics, computer programming, hydrology and water
management has been assumed.
The book concentrates mainly on the problems of effective water supply and water
resource conservation in water resource systems. The issue of water quality in watercourses
and the special issues of waterworks, sewerage, navigation and hydroelectric
power generation have not been analysed in detail apart from the aspect of water
resource management.
More attention should be paid to the subsystem of flood control, its relationship
to the environment and its technical and economic relationships to water supplydemand
integration. A reference for more detailed investigation is given.
In the branches of science which deal with systems many issues and questions
have to be answered. This is also true of those disciplines where the systems approach
and the application of systems sciences were first introduced, e. g. automatic control
and economics; it naturally applies to the problems of water management, as proved,
for example, by five international symposia - “Water Resource Systems” held in
Czechoslovakia, first in Karlovy Vary, 1972, and the last in Znojmo, 1987.
The book sets out to offer the reader a set of principles and methods for dealing
with water resource systems on a scientific basis.It is hoped that, along with the basic
facts, it will provide an impetus to the further development of promising progressive
methods of dealing with the problems of water management by means of a systems
approach.
The theme of this book won a place in a competition held by the Czech Society of
Engineers and the Publishers of Technical Literature. The authors are indebted to
these institutes for the publication of this book.
The authors wish to express their special thanks to the following institutions:
Water Resources Development and Construction, Technical University of Prague,

As a wetland of international importance located in China ,the Poyang Lake Basin's incredible topographical and biological diversity has provided a congregating point for scientists from around the world to engage in cross-disciplinary research. In particular, the International Conference on Poyang Lake Complex Environment System was instrumental in bringing together scholars from China, North America, and Europe to explore the latest innovations in water resource science and watershed management. Featuring cutting-edge research in watershed management presented at this landmark event, Wetland and Water Resource Modeling Assessment pairs the accounts of Poyang Lake with additional information on the important watersheds of North America and Asia to help facilitate the development of decision support tools. The book explains that successful ecosystem assessment and modeling requires three key criteria: 1. Large spatial scales in data collection and analysis must be used to encompass major watershed features 2. Landscape features are needed to appropriately characterize hydrological processes and ecosystem components 3. Management decisions must be linked to results to facilitate ecosystem assessment Through the study of the diverse watersheds featured in Wetland and Water Resource Modeling Assessment, such as Poyang Lake, government, academia, and Industry can obtain the innovative technical tools needed to stay on top of this active field.

Industrial desalination of sea and brackish water is becoming an essential part in providing sustainable sources of fresh water for a larger number of communities around the world. Desalination is a main source of fresh water in the Gulf countries, a number of the Caribbean and Mediterranean Islands, and several municipalities in a large number of countries. As the industry expands there is a pressing need to have a clear and well-written textbook that focuses on desalination fundamentals and other industrial aspects.
This book focuses on the processes widely used in industry, which include multistage flash desalination and reverse osmosis. Also, other desalination processes with attractive features and high potential are featured.
It includes a large number of solved examples, which are explained in simple and careful matter that allow the reader to follow and understand the development. The data used in the development of the examples and case studies are extracted from existing desalination plants.
This title also includes comparisons of model predictions against results reported in literature as well as available experimental and industrial data. Several industries include similar unit operation processes, i.e., evaporators, condensers, flashing units, membrane separation, and chemical treatment. Examples of such industries include wastewater treatment, food, petroleum, petrochemical, power generation, and pulp and paper. Process fundamentals and design procedures of such unit processes follow the same procedures given in this textbook.

Effective Groundwater Model Calibration: With Analysis of Data, Sensitivities, Predictions, and Uncertainty
Author: Mary C. Hill, Claire R. Tiedeman | Size: 6.35 MB | Format:PDF | Publisher: Wiley-Interscience | Year: 2007 | pages: 480 | ISBN: 047177636X and 9780471776369
Product Description:
Methods and guidelines for developing and using mathematical models
Turn to Effective Groundwater Model Calibration for a set of methods and guidelines that can help produce more accurate and transparent mathematical models. The models can represent groundwater flow and transport and other natural and engineered systems. Use this book and its extensive exercises to learn methods to fully exploit the data on hand, maximize the model's potential, and troubleshoot any problems that arise. Use the methods to perform:
Sensitivity analysis to evaluate the information content of data
Data assessment to identify (a) existing measurements that dominate model development and predictions and (b) potential measurements likely to improve the reliability of predictions
Calibration to develop models that are consistent with the data in an optimal manner
Uncertainty evaluation to quantify and communicate errors in simulated results that are often used to make important societal decisions
Most of the methods are based on linear and nonlinear regression theory.
Fourteen guidelines show the reader how to use the methods advantageously in practical situations.
Exercises focus on a groundwater flow system and management problem, enabling readers to apply all the methods presented in the text. The exercises can be completed using the material provided in the book, or as hands-on computer exercises using instructions and files available on the text's accompanying Web site.
Throughout the book, the authors stress the need for valid statistical concepts and easily understood presentation methods required to achieve well-tested, transparent models. Most of the examples and all of the exercises focus on simulating groundwater systems; other examples come from surface-water hydrology and geophysics.
The methods and guidelines in the text are broadly applicable and can be used by students, researchers, and engineers to simulate many kinds systems.
