Book Description
The United States repeatedly experiences floods along the Midwest's large rivers and droughts in the arid Western States that cause traumatic environmental disasters with huge economic impact. These problems can be alleviated with an integrated approach and comprehensive solution. Withdrawing flood water from the Mississippi River and its tributaries will mitigate the damage of flooding and provide a new resource of fresh water to the Western States. The existence of a trend of increasing heavy precipitation and flooding on the Midwest's Rivers is supported by a growing body of scientific literature that documents the effects of climate change since 1993. Flooding in Iowa, North Dakota, Tennessee, Arkansas and along the Mississippi River from 1993 to 2010 are prime examples. The Colorado River Basin and the western states are experiencing a protracted multi-year drought. Fresh water can be pumped via pipelines and aqueducts from areas of overabundance/flood to areas of drought or high demand. Calculations document 10 to 60 million acre feet (maf) of fresh water per flood event can be captured from the Midwest's Rivers and pumped via pipelines to the Colorado River and introduced upstream of Lake Powell, Utah, also to destinations near Denver, Colorado, and used in areas along the new water transportation routes. Water users of the Colorado River include the cities in southern Nevada, southern California, northern Arizona, Colorado, Utah, Indian Tribes, and Mexico. The proposed starting, end points, and routes of the water transportation routes are documented, including information on right-of-ways necessary for state and federal permits. The National Smart Water Grid™ (NSWG) could create a million new jobs for construction, operation, and maintenance and save billions per year in drought and flood damage reparations tax dollars. The socio-economic benefits include decreased flooding in the Midwest; increased agriculture, and recreation and tourism; improved national security, transportation, and fishery and wildlife habitats; decreased salinity in Colorado River water crossing the US-Mexico border; and decreased eutrophication/hypoxia (excessive plant growth and decay) in the Gulf of Mexico to name a few. The sale of captured flood water could pay for the National Smart Water Grid™. The cost benefit analysis indicates that the NSWG should be net beneficial. A detailed feasibility studies for each pipeline/aqueduct transportation route is warranted.The Second Edition expands flooding and recent climate change data, emphasis on cost/benefit analysis, details on the engineered features such as pipes, pumps, aqueducts, and patent pending modified levees.Water is a $400 billion industry, the third largest behind oil and electricity. The U.S. has a Strategic Petroleum Reserve and needs a comparable Strategic Water Reserve. The National Smart Water Grid could become a Strategic Water Reserve and augment the National Energy Grid. The availability and sustainability of freshwater is the most important issue facing humanity in this century.

Smart Water Grids
Author: Panagiotis Tsakalides
Publisher: CRC Press
ISBN: 1351986163
Category : Technology & Engineering
Languages : en
Pages : 323
Book Description
The effects of climate change, rapid urbanization, and aging infrastructure challenge water policymakers to confront a radical paradigm shift in water resources utilization. Recent advances in sensing, networking, processing, and control have provided the means for sustainable solutions in water management, and their implementation in water infrastructures is collectively referred to as "smart water grids." Smart water grids depend upon cyber-physical system principles to effectively respond to issues regarding the scalability and reliability of dynamic and inaccessible environments. As such, unique smart water grid issues associated with front-end signal processing, communication, control, and data analysis must be jointly addressed, while sophisticated techniques for data analytics must be introduced into cyber-physical systems research. This book provides a thorough description of the best practices for designing and implementing cyber-physical systems that are tailored to different aspects of smart water grids. It is organized into three distinct, yet complementary areas, namely: the theory behind water-oriented cyber-physical systems with an emphasis on front-end sensing and processing, communication technologies, and learning techniques over water data; the applications and emerging topics of cyber-physical systems for water urban infrastructures, including real-life deployments, modern control tools, and economic aspects for smart water grids; and the applications and emerging topics across natural environments, emphasizing the evolution of fresh water resources. The structured discussion yields a rich, comprehensive body of knowledge on this emerging topic of research and engineering. As water issues intensify on a global scale, this book offers an algorithmic and practical toolkit for intermediate and advanced readers as well as professionals and researchers who are active in, or interested in, learning more about smart water grids. Key Features: Emphasizes the multidisciplinary nature of this emerging topic, covering both theoretical and practical aspects of this area while providing insights on existing deployments, which can serve as design examples for new applications. Explores how modern signal processing and machine learning techniques can contribute and enrich the potential of smart water grids, well beyond conventional closed-loop control techniques. Highlights complementary aspects that will help shape the future of smart water grids, such as consumption awareness, economic aspects, and control tools in industrial water treatment as well as the impact of climate change on fresh water resources. Enables the reader to better understand this emerging topic, investing in current state-of-the-art and future technological roadmaps for smart water grids.

Smart Water Utilities
Author: Pernille Ingildsen
Publisher: IWA Publishing
ISBN: 1780407572
Category : Science
Languages : en
Pages : 307
Book Description
Today there is increasing pressure on the water infrastructure and although unsustainable water extraction and wastewater handling can continue for a while, at some point water needs to be managed in a way that is sustainable in the long-term. We need to handle water utilities “smarter”. New and effective tools and technologies are becoming available at an affordable cost and these technologies are steadily changing water infrastructure options. The quality and robustness of sensors are increasing rapidly and their reliability makes the automatic handling of critical processes viable. Online and real-time control means safer and more effective operation. The combination of better sensors and new water treatment technologies is a strong enabler for decentralised and diversified water treatment. Plants can be run with a minimum of personnel attendance. In the future, thousands of sensors in the water utility cycle will handle all the complexity in an effective way. Smart Water Utilities: Complexity Made Simple provides a framework for Smart Water Utilities based on an M-A-D (Measurement-Analysis-Decision). This enables the organisation and implementation of “Smart” in a water utility by providing an overview of supporting technologies and methods. The book presents an introduction to methods and tools, providing a perspective of what can and could be achieved. It provides a toolbox for all water challenges and is essential reading for the Water Utility Manager, Engineer and Director and for Consultants, Designers and Researchers.
