The field of ecohydraulics integrates hydrodynamic and eco-dynamic processes. While hydrodynamic processes are usually well described by partial differential equations (PDE's) based on physical conservation principles, ecosystem dynamics often involve specific interactions at the local scale. Because of this, Cellular Automata (CA) are a viable paradigm in ecosystem modelling. All cells in a CA system update their states synchronously at discrete steps according to simple local rules. The classi...

This holistic book covers the richest area in North East India in terms of both explored and foreseen reserves of fossil fuels and other natural resources. Using a multidisciplinary approach, GIS, and geospatial data gathered from different case studies included, this book helps readers develop a thorough understanding of a highly dynamic big river, the Brahmaputra, and use it as a comprehensive resource for further understanding the science of rivers. It discusses the causal factors of decadal-...

Flood based irrigation in particular spate irrigation relies on variable flood scenarios occurring every year. Management of spate flood for spate irrigation must cope with the variability and uncertainty of water supply. Coping with water supply risks is often the only way to harness the opportunities for a productive use of water in arid environment. Integrating and strengthening community responses into irrigation policies and improvement plans could ensure sustainable and productive spate ir...

In the past decade, practical applications of a variety of new wastewater-treatment technologies, such as membrane filtration systems and advanced oxidation, have led to new ways of managing urban water systems and water resources. These new treatment regimes, especially the integration of urban-water and waste-management systems, promise to dramatically improve the sustainability of our water resources. These new systems are creating new needs, which are driving further technology development....

This edited book has been designed to serve as a natural resources engineering reference book as well as a supplemental textbook. This volume is part of the Handbook of Environmental Engineering series, an incredible collection of methodologies that study the effects of resources and wastes in their three basic forms: gas, solid, and liquid. It complements two other books in the series including "Natural Resources and Control Processes" and "Environmental and Natural Resources Engineering". To...

Environmental engineers work to increase the level of health and happiness in the world by designing, building, and operating processes and systems for water treatment, water pollution control, air pollution control, and solid waste management. These projects compete for resources with projects in medicine, transportation, education, and other fields that have a similar objective. The challenge is to make the investments efficient – to get the best project outputs with a minimum of inputs. Cost...

Mikroorganismen kommen naturlicherweise im Grund- und Trinkwasser vor. Kritisch wird es dann, wenn pathogene Keime im Trinkwasser auftreten. Das vorliegende Buch gibt einen umfassenden Einblick in den Wissensstand zum Transport von Mikroorganismen im Grundwasser und zeigt die Bedeutung der pathogenen Mikroorganismen fur die menschliche Gesundheit sowie das Epidemienrisiko auf. Es stellt neuste und zukunftige Nachweismethoden vor und bietet Loesungsstrategien fur die Erhaltung einer guten Trinkwa...

Charles Ortloff provides a new perspective on archaeological studies of the urban and agricultural water supply and distribution systems of the major ancient civilizations of South America, the Middle East, and South-East Asia, by using modern computer analysis methods to extract the true hydraulic/hydrological knowledge base available to these peoples. His many new revelations about the capabilities and innovations of ancient water engineers force us to re-evaluate what was known and practised...

This standard covers the minimum requirements for the installation of ductile-iron water mains and their appurtenances, including materials, dimensions, tolerances, and testing procedures.

This book reviews a selection of organic-geochemical investigations, dealing with the characterization and environmental behaviour of organic contaminations of German river and groundwater systems. Topics include comprehensive non-target screening as well as isotope analysis of contaminants in water and sediments, detailed characterisation of bound residues, recording riverine pollution histories and an extensive application of the anthropogenic marker approach.

Make the best use of available water for your crops!Water Use in Crop Production explores innovative methods that determine how much water certain crops need, in certain climates, in order to ensure adequate plant growth and help eliminate water waste. Through this informative book, agronomists, growers, researchers, and graduate students will find methods and techniques for effective water management that will save money and conserve water. Water Use in Crop Production will enable you enhance c...

Management of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focused on the development of an innova...

This volume discusses the current challenges related to the reuse of wastewater. It reviews the analytical methodologies for evaluating emerging contaminants and their transformation products, the sensitivity of various bioassays for assessing the biological effects of treated wastewater, and the bioavailability and uptake of organic contaminants during crop irrigation. It describes in detail the physicochemical and microbiological alterations in soil resulting from irrigation with treated urban...

Florida's Water poses fundamental questions about water sustainability in the United States' fourth largest state. Florida has long-standing water quality problems. Global climate change threatens to intensify Florida's floods and droughts, make hurricanes more common or more damaging, and eventually submerge much of low-lying Florida, including the Everglades. How can Florida meet these extraordinary challenges? And what lessons does the Florida experience hold for other states? This book full...

This standard includes requirements that are limited exclusively to operation and management practices for reclaimed water programs.

Natural disasters, tornadoes, hurricanes, and floods are occurring with increasing frequency. In emergencies, pure drinking water is quickly the most important item. Low Cost Emergency Water Purification Technologies provides the tips and techniques for supplying potable drinking water at low cost in the direst circumstances. Succinct and readable, this manual describes the various options for correcting unsanitary or unsatisfactory drinking water. Several treatment methods for contaminated wa...

This standard covers protective fusion-bonded coatings for the interior and exterior surfaces of ductile-iron and gray-iron fittings used for raw water, potable water, wastewater, and reclaimed water systems.

Although much has been done to simplify US drinking water regulations, a confusing array of technical information still exists, and sorting it all out is problematic. This operations-oriented book explains all the regulations and how they fit together. The book provides regulatory guidance and advisories related to USEPA regulations in a single, easy-to-follow guide. It compiles information from USEPA, AWWA, and others and presents it in an understandable format. Useful to water utility managers...

Modeling the fate of chemical constituents such as cations and anions, organic and inorganic ligands, etc., is essential to understand the long-term utility of groundwater for various purposes. The chemical modeling helps to describe the chemical characteristic of an aqueous system to solve a simultaneous set of equations, which explains the equilibrium reactions and mass balance on dissolved element for the output consists of theoretical distribution of aqueous species for dissolved elements....
