Available in PDF, EPUB and Kindle. Book excerpt: This newly published book is an organized collection of papers dealing with changes in the quality of water as it moves through the world's hydrologic cycle-from the sea, lakes, and rivers-to its hydrosphere and then back to earth as precipitation, where the water again percolates through the soil or falls on the ocean, rivers, or lakes. (Changes that occur are physical, chemical, and biological.) Though chapters discuss results of specific lab or field experiments which in themselves have value for the scientist, focus is on processes involved. Many general concepts of water quality are provided in this cohesively organized book.

Available in PDF, EPUB and Kindle. Book excerpt: The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from activities of man. Some of the processes of solution or precipitation of minerals can be closely evaluated by means of principles of chemical equilibrium including the law of mass action and the Nernst equation. Other processes are irreversible and require consideration of reaction mechanisms and rates. The chemical composition of the crustal rocks of the earth and the composition of the ocean and the atmosphere are significant in evaluating sources of solutes in natural fresh water. The ways in which solutes are taken up or precipitated and the amounts present in solution are influenced by many environmental factors, especially climate, structure and position of rock strata, and biochemical effects associated with life cycles of plants and animals, both microscopic and macroscopic. Taken all together and in application with the further influence of the general circulation of all water in the hydrologic cycle, the chemical principles and environmental factors form a basis for the developing science of natural-water chemistry. Fundamental data used in the determination of water quality are obtained by the chemical analysis of water samples in the laboratory or onsite sensing of chemical properties in the field. Sampling is complicated by changes in composition of moving water and the effects of particulate suspended material. Most of the constituents determined are reported in gravimetric units, usually milligrams per liter or milliequivalents per liter. More than 60 constituents and properties are included in water analyses frequently enough to provide a basis for consideration of the sources from which each is generally derived, most probable forms of elements and ions in solution, solubility controls, expected concentration ranges and other chemical factors. Concentrations of elements that are commonly present in amounts less than a few tens of micrograms per liter cannot always be easily explained, but present information suggests many are controlled by solubility of hydroxide or carbonate or by sorption on solid particles. Chemical analyses may be grouped and statistically evaluated by averages, frequency distributions, or ion correlations to summarize large volumes of data. Graphing of analyses or of groups of analyses aids in showing chemical relationships among waters, probable sources of solutes, areal water-quality regimen, and water-resources evaluation. Graphs may show water type based on chemical composition, relationships among ions, or groups of ions in individual waters or many waters considered simultaneously. The relationships of water quality to hydrologic parameters, such as stream discharge rate or ground-water flow patterns, can be shown by mathematical equations, graphs, and maps. About 75 water analyses selected from the literature are tabulated to illustrate the relationships described, and some of these, along with many others that are not tabulated, are also utilized in demonstrating graphing and mapping techniques. Relationships of water composition to source rock type are illustrated by graphs of some of the tabulated analyses. Activities of man maymodify water composition extensively through direct effects of pollution and indirect results of water development, such as intrusion of sea water in ground-water aquifiers. Water-quality standards for domestic, agricultural, and industrial use have been published by various agencies. Irrigation project requirements for water quality are particularly intricate. Fundamental knowledge of processes that control natural water composition is required for rational management of water quality.

Download or read book Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.
Book Synopsis Introduction to Water Resources by : John C. Clausen
Download or read book Introduction to Water Resources written by John C. Clausen and published by Waveland Press. This book was released on 2017-09-29 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of water resources crosses disciplinary boundaries, from geography and natural resources, to Earth sciences, environmental studies, and engineering. Since not all students come to the water-resources course with the same mathematical background, Clausen’s effective, practical presentation integrates topics related to water quantity and water quality. He emphasizes fundamental concepts throughout: the qualitative foundations of hydrology needed to understand the hydrologic cycle and water availability, as well as the physical, chemical, and biological principles underlying water quality. Important social-science issues, including water law and regulations, the economic principles of water supply and demand, and sustainable water management, contextualize the material. Abundant illustrations and purposeful examples reinforce chapter content. End-of-chapter problems provide opportunities for readers to practice the calculations needed for real-world applications.
Book Synopsis The Science of Water by : Frank R. Spellman
Download or read book The Science of Water written by Frank R. Spellman and published by CRC Press. This book was released on 1998-03-09 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is a limited resource. The average person might ask how this can be? We are literally shrouded in water-water covers most of the earth-water, water, water, everywhere you look there is water. Obviously, this person does not live in or is not familiar with arid and semi-arid parts of the globe. Maybe our viewer is referring to the hydrologic cycle-that natural process of rainfall-runoff-evaporation, which repeats itself continuously (we can only hope that it continues to do so). Our viewer is not alone in his/her assessment of water-the state of water-the fact is most people do not give water a second thought. A belief prevails that the earth's finite water resources can be increased constantly to meet growing demands. At the present time, the supply of water is constantly made to respond to demand. Modern technology has allowed us to tap potable water supplies and to design and construct elaborate water distribution systems. We have developed technology to treat water we foul, soil, pollute, discard, and flush away. History has demonstrated that consumption and waste increase in response to rising supply. But the fact remains: fresh waters are a finite source-one that can be increased only slightly through desalinization or some other practice-all at tremendous cost. If water is so precious, so necessary for sustaining life, then two questions arise: 1. Why do we ignore water? 2. Why do we abuse it (pollute or waste it)? We ignore water because it is so common, so accessible, so available, so unexceptional (unless you are lost in the desert without a supply of it) that we don't have to think about it. Why do we pollute and waste water? Several reasons are discussed in this text. This text deals with the essence of water: what water is, and what water is all about. While this text points out that water is one of the simplest and most common chemical compounds on earth, it is also one of the most mysterious and awe-inspiring substances we know. Essential to this discussion of water and its critical importance on earth is man-man and his use, misuse, and reuse of fresh water and wastewater. Since water is the essence of all life on earth, it is precious-too precious to abuse, misuse and ignore. The common thread woven through the fabric of this presentation is water resource utilization and its protection.

Download or read book Water Quality Data written by Arthur Hounslow and published by CRC Press. This book was released on 2018-02-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Quality Data emphasizes the interpretation of a water analysis or a group of analyses, with major applications on ground-water pollution or contaminant transport. A companion computer program aids in obtaining accurate, reproducible results, and alleviates some of the drudgery involved in water chemistry calculations. The text is divided into nine chapters and includes computer programs applicable to all the main concepts presented. After introducing the fundamental aspects of water chemistry, the book focuses on the interpretation of water chemical data. The interrelationships between the various aspects of geochemistry and between chemistry and geology are discussed. The book describes the origin and interpretation of the major elements, and some minor ones, that affect water quality. Readers are introduced to the elementary thermodynamics necessary to understand the use and results from water equilibrium computer programs. The book includes a detailed overview of organic chemistry and identifies the simpler and environmentally important organic chemicals. Methods are given to estimate the distribution of organic chemicals in the environment. The author fully explains all accompanying computer programs and presents this complex topic in a style that is interesting and easy to grasp for anyone.
Book Synopsis Water Resources and Water Management by : M.K. Jermar
Download or read book Water Resources and Water Management written by M.K. Jermar and published by Elsevier. This book was released on 1987-01-01 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Water Quality written by Claude E. Boyd and published by Springer Nature. This book was released on 2019-09-12 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

Download or read book Water Quality written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water quality is important to everyone, but professionals in many disciplines need an understanding of this subject. Although water quality is complex, its general aspects can be grasped readily and with little background - only introductory chemistry and biology and a little algebra are needed. Unfortunately, the teaching of water quality is not well organized. In most colleges and universities, water quality instruction is given in certain engineering curricula and in aquatic ecology or fisheries curricula. There also is brief attention to selected topics on water quality in numerous classes in other curricula. Water quality training in engineering is highly specialized and directed by necessity towards water supply and water treatment, while the focus in aquatic ecology and fisheries is on biological water quality and pollution. Few students venture into specialized classes outside of their curricula, and as a result, their formal training in water quality is greatly restricted. Self-education by reading texts and reference books on water quality is difficult. Authors of water quality books seem to be more interested in presenting a rigorous, detailed treatment than in focusing on simplicity and clarity. Chemical aspects of water quality often are presented at a level requiring fairly advanced mathematics and physical chemistry, and biological discussions may be quite advanced and theoretical. I have taught water quality to seniors and graduate students in agriculture, wildlife and fisheries, environmental sciences, economics, and similar disciplines for many years.
