Download or read book Stream Ecology and Self-Purification written by Frank R. Spellman and published by CRC Press. This book was released on 1996-07-01 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Preface This text is designed to provide a fundamental knowledge of the phenomenon known as self-purification in streams. Sufficient background information and references on stream ecology and self-purification are presented to provide readers with an understanding of the various concepts under discussion. Moreover, along with the stream self-purification process and biological indication of stream health, water quality and source sampling are discussed in depth. Wastewater and water treatment personnel, students, specialists, water resource managers, ecologists, regulators, and water pollution control personnel concerned with activities and preventive measures to prevent stream pollution will find this consolidated information important. Other professional wastewater- and water-related staff from governmental agencies, municipal water supply and wastewater systems, public health departments, and environmental health agencies will also find the information valuable. This text, however, is also intended for readers and groups interested in and concerned with stream pollution and stream contamination control. This text can be used as a basic or supplemental text in undergraduate and technical school courses in aquatic ecology or stream quality enhancement and protection. It can also be consulted as an environmental reference text by school, municipal, and water resource professionals.

Download or read book Stream Ecology and Self Purification written by Frank R. Spellman and published by CRC Press. This book was released on 2001-06-05 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of a very successful standard reference is expanded and fully reworked. The book explains and quantifies the processes whereby streams cleanse themselves, reducing their pollutant load as a natural process. Mechanisms of purification in running waters have always been critical with regard to clearly identified pollution sources. This new edition explains the self-purifying function of streams and rivers in light of recent EPA rules on nonpoint pollutants and total maximum daily loads (TMDLs). It also covers basic concepts such as biological oxygen demand (BOD). Also new in this edition is an extended discussion of how streams originate and how they fit into the geomorphology of the earth and other water supply sources. Information is presented on aquatic life, including macroinvertebrates and their role as bioindicators of stream health. Chapter review tests and answers are included so that the readers can evaluate their mastery of the concepts presented. Stream Ecology and Self-Purification: An Introduction, 2nd Edition serves as a practical introduction to ecology combined with an explanation of how streams absorb and react to pollution. This text will prove valuable to water and wastewater plant operators, watershed managers, trainers, environmental students, water quality professionals, and will be an excellent preparation aid to wastewater/water operator licensing exams.

Book excerpt: Water is the most plentiful liquid on earth. It is a requirement for all life, whether it is used in metabolic processes, as a solvent of minerals, or in the disposal of waste. Indeed, it is difficult to name a natural phenomenon in which water, in one form or another, has not had a role. Nature has provided for the conservation of this abundant and valuable liquid by endowing it with a considerable capacity to rid itself of foreign substances. This process, known as self-purification, is an inherent property of water. The water may be moving in streams or be relatively static as in lakes and ponds, but the natural processes of purification are similar. Advantage is taken of this intrinsic ability of water to purify itself by using it as a final stage in the treatment of sewage and industrial wastes. Streams polluted by domestic wastes (those derived from human populations) or industrial wastes (the liquid wastes of wet-process industries and acid mine drainage) may be rendered stable by self-purification. In most instances, such polluted water becomes relatively innocuous biologically and again serves nature in one role or another. This purification is accomplished by a combination of physical, chemical, and biological forces. The extent to which each force operates is dependent upon the type of contamination. Physical forces dispose of suspended solids; chemical forces cause reactions which render unstable wastes innoxious; and biological forces contribute to the stability of the stream by enhancing both physical and chemical phenomena. The biological forces are the most active, and the most important, in the equilibration of a stream.

This book was released on 1960 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A simplified technique is proposed for determining the self-purification coefficient in surface streams. A formula for f is derived from the basic Streeter-Phelps (1925) oxygen-sag equation. The technique proposed for use of this formula appears to offer many possibilities for studying the oxygen balance of water in both laboratory and field investigations. The value of the technique is in its simplicity. It requires only three measurements: temperature, dissolved oxygen, and BOD. The need to determine k1, k2, or time-of-flow is eliminated."--Abstract.

Book excerpt: Excerpt from Dissolved Oxygen and Its Influence in Self-Purification of Streams Te reach, a thorough understanding of the amount of the pur ification of running water; its causes and the influences of en virement on its causes, is a task which has not yet been finished with sufficient accuracy and certainty to satisfy the minds of that part or the chemical world which is interested in water analysis. There are even now several chemists' of note who hesitate to admit that any natural purification other than a small oxidation and a large dilution, takes place. But the larger proportion of the authorities agree that there is a pur ificatian which takes place threugh natural causes, the amount or which has not been determined, and for Which the causes are so varied that probably no definite ratio of purification to length of flow, exists.

Download or read book Rivers for Life written by Sandra Postel and published by Island Press. This book was released on 2012-06-22 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.
