By 2050, the demand for water to sustain world agriculture will increase by seventy-five per cent in order to feed an estimated nine billion inhabitants. Increased amounts of water will be required for irrigation and for industrial and domestic use. Natural ecosystems will be threatened by the expansion of agricultural land and by a reduction in water availability, while climate change will exacerbate the situation. Management of available resources, particularly groundwater, will become more critical and aquifers will need to be managed for the benefit of all. These selected papers were first presented at the International Association of Hydrogeologists, Dijon 2006, and are divided into six themes: large aquifers, resource assessment; large aquifers, water salinity and evolution; karstic and carbonate aquifer systems; geothermal aquifer systems; aquifer contamination studies and aquifer monitoring systems and management. The volume also includes a short biography of Henry Darcy and illustrates his contribution to science. Five invited contributions describe modern methods for estimating the hydraulic conductivity of aquifers.

In this social and ecological account of the Chicago River, Libby Hill tells the story of how a sluggish waterway emptying into Lake Michigan became central to the creation of Chicago as a major metropolis and transportation hub. This widely acclaimed volume weaves the perspectives of science, engineering, commerce, politics, economics, and the natural world into a chronicle of the river from its earliest geologic history through its repeated adaptations to the city that grew up around it. While explaining the river's role in massive public works, such as drainage and straightening, designed to address the infrastructure needs of a growing population, Hill focuses on the synergy between the river and the people of greater Chicago, whether they be the tribal cultures that occupied the land after glacial retreat, the first European inhabitants, or more recent residents. In the first edition, Hill brought together years of original research and the contributions of dozens of experts to tell the Chicago River's story up until 2000. This revised edition features discussions of disinfection, Asian carp, green strategies, the evolution of the Chicago Riverwalk, and the river's rejuvenation. It also explores how earlier solutions to problems challenge today's engineers, architects, environmentalists, and public policy agencies as they address contemporary issues. Revealing the river to be a microcosm of the uneasy relationship between nature and civilization, The Chicago River offers the tools and knowledge for the city's residents to be champions on the river's behalf.

The Manchester Ship Canal was a huge engineering achievement. It included seven swing bridges and the aqueduct at Barton, and helped turn the cotton-producing capital of Great Britain into an inland seaport. This was a feat many at the time believed could not be achieved. One of the wonders of the modern industrial world, the Manchester Ship Canal, with its huge locks and ocean-going vessels, was a magnetic draw for enthusiastic Victorians who marvelled at its construction. This book looks at the changes and development of the Manchester Ship Canal through time, from its origins as a thriving economic hub in the late nineteenth century, to an important retail, leisure and media centre in the early twenty-first century and beyond. Join Steven Dickens as he explores the history of this 36-mile-long inland waterway in the north-west of England, which links Manchester to the Mersey Estuary and the Irish Sea.

From acclaimed writer Beth Kephart, author of A Slant of Sun, comes a short, imaginative telling of the life of the Schuylkill River, which has served as the source of Philadelphia's water, power, industry, and beauty for the city's entire life. Before that, it fed the indigenous people who preceded William Penn, and has since time immemorial shape our region.

Founded as a port at the confluence of two great rivers, Kansas City has the waters of the Missouri running through its bloodstream-threading expressways, delivering drinking water, carrying traffic and sewage, and emerging most visibly in the city's celebrated fountains. Despite, or perhaps because of, the river's ubiquity, the complex and critical nature of its presence can be hard to understand, which is precisely why Amahia Mallea's enlightening book is so essential. Moving from the city's center to the outer limits of the metropolitan area, A River in the City of Fountains offers a clear view of the reach and intricacies of the Missouri River's connection to life in Kansas City. The history of this connection is one of science and industry working, sometimes at cross-purposes, to bend the river to the needs of commerce and public health. It is a story populated with heroes and villains, visionaries and robber barons, scientists and civil engineers, politicians and activists-all with schemes and plans and far-reaching ideas about what, and whose, demands the power of the Missouri should serve. And so, inevitably, it is a story of disparities: a story of, from one flood to the next, the haves staking out higher ground, leaving the have-nots to the perils of low-lying land. But what the book also shows us is a slow awakening to the ways in which all those vying for the river's favor are inextricably connected by its course; here we see, finally, a growing awareness of the river's essential role in the health and welfare of the whole urban environment. In the end, all citizens of Kansas City are both upstream and downstream; all are equally dependent on the health of the river. What this book helps us see is, at last, as much the city in the river as the river in the city.

The poor quality of water, as well as its restricted supply and availability, is one of the biggest challenges of our time, with presently two-fifth's of the world's population unable to find adequate fresh water for essential usage. Over 40 years' research has been carried out on the positive effects that rhythms and specific water flow has on water's capacity to support life. Energizing Water presents this cutting-edge research to the general and professional reader at a time when interest in finding solutions to water's huge worldwide problems is growing rapidly. Three aspects determine water quality: its chemical constituents (including its oxygen levels); its organic aspects (with the danger of contamination by effluent, pathogens and algae); and its 'energetic' nature. The latter facet has been recognized from time immemorial by traditional societies, who have developed their own sciences in relation to water quality, using terms such as prana and chi for energy. Now, through the introduction of quantum physics into the life sciences, modern science is beginning to accept this concept, measuring energy as light emission. Research into energetic water quality - and particularly into the creation of moulded surfaces that support biological purification of the chemical and organic elements, as well as enlivening the energetic attributes - goes back to George Adams' and John Wilkes' pioneering work in the 1960s. The invention of Flowform technology in 1970 carried this research further, providing the world with one of the first modern-day, biomimicry eco-technologies. This creative technology applies nature's best methods to produce extraordinary results, and this book outlines the background story on research and application of the Flowform method today.

Ecohydrology is an emerging new sub-discipline which links elements of ecology with hydrology at all points in the water cycle, ranging in scale from water-plant physiological relationships to whole catchment water-ecosystem processes. This book pays most attention to the larger scales of ecohydrology, emphasising the use of this tool in striving towards the goal of sustainable water management. Authors from Eastern as well as Western Europe; from America, Australia and South Africa, give a broad global context.

This comprehensive, two-volume review of the atmospheric and hydrologic sciences promises to be the definitive reference for both professionals and laypersons for years to come. Volume I addresses atmospheric dynamics, physical meteorology, weather systems, and measurements, while Volume II contains information on the climate system, atmospheric chemistry, hydrology, and societal impacts.

Grand Canyon has been saved from dams three times in the last century. Unthinkable as it may seem today, many people promoted damming the Colorado River in the canyon during the early twentieth century as the most feasible solution to the water and power needs of the Pacific Southwest. These efforts reached their climax during the 1960s when the federal government tried to build two massive hydroelectric dams in Grand Canyon. Although not located within the Grand Canyon National Park or Monument, they would have flooded lengthy unprotected reaches of the canyon and along thirteen miles of the park boundary. Saving Grand Canyon tells the remarkable true story of the attempts to build dams in one of America's most spectacular natural wonders. Based on twenty-five years of research, this fascinating ride through history chronicles a century of Colorado River water development demonstrates how the National Environmental Policy Act came out of these controversies, and debunks the myth that the Sierra Club saved Grand Canyon. It also shows how the Sierra Club parlayed public perception as the canyon's savior into the leadership of the modern environmental movement after the National Environmental Policy Act became law. The tale of the Sierra Club stopping the dams has become so entrenched-and so embellished-that many historians, popular writers, and filmmakers have ignored the documented historical record. This epic story puts the events from 1963-68 into the broader the context of Colorado River water development and debunks 50 years of Colorado River water development and Grand Canyon history.

This latest collaboration of Carolyn V. Platt and Gary Meszaros is a beautifully photographed book that explores Lake Erie and its effects on the birds that make this region their home. Birds of the Lake Erie Region observes a year of weather changes and avian migrations--from the wintertime convergence of ducks and other waterbirds on the lake's last ice-free areas to the excitement of the raptor and shorebird migrations in the fall. Expert or novice, birders and nature lovers will be moved by Platt's celebration of these birds and their habitat and by Meszaros's impressive photographs of the delicate beauty of these exquisite creatures.

India is killing the Ganges, and the Ganges in turn is killing India. The waterway that has nourished more people than any on earth for three millennia is now so polluted with sewage and toxic waste that it has become a menace to human and animal health. Victor Mallet traces the holy river from source to mouth, and from ancient times to the present day, to find that the battle to rescue what is arguably the world's most important river is far from lost. As one Hindu sage told the author in Rishikesh on the banks of the upper Ganges (known to Hindus as the goddess Ganga) - 'If Ganga dies, India dies. If Ganga thrives, India thrives. The lives of 500 million people is no small thing.' Drawing on four years of first-hand reporting and detailed historical and scientific research, Mallet delves into the religious, historical, and biological mysteries of the Ganges, and explains how Hindus can simultaneously revere and abuse their national river. Starting at the Himalayan glacier where the Ganges emerges pure and cold from an icy cave known as the Cow's Mouth and ending in the tiger-infested mangrove swamps of the Bay of Bengal, Mallet encounters everyone from the naked holy men who worship the river, to the engineers who divert its waters for irrigation, the scientists who study its bacteria, and Narendra Modi, the Hindu nationalist prime minister, who says he wants to save India's mother-river for posterity. Can they succeed in saving the river from catastrophe - or is it too late?

Rivers and streams around the world that once flowed wild and unchecked are rapidly disappearing into dams or being channelized between concrete banks. This valuable sourcebook, now available to a wide audience in a paperback edition, is an important comparative documentation of what is being lost: naturally flowing river and stream ecosystems. No other single volume brings together so much critical information on rivers and streams worldwide. Each chapter is packed with a wealth of raw data on waterways including the prominent rivers of North America, Central and South America, Europe, Africa, Australia, and Oceania. The volume evaluates the usefulness of the River Continuum Concept and ecosystem-level measurements for evaluating the structure and function of rivers and streams. The new introductory chapter examines the relevance of other useful concepts including Nutrient Spiraling, Patch Dynamics, the Flood Pulse Concept, the Network Dynamics Hypothesis, and the Hyporheic Corridor Concept.

Kinematic wave modeling methods are gaining wide acceptance as a fast and accurate way of handling a wide range of water modeling problems. This is the first book to provide a thorough reference to the application of KW methods to such problems as the spatial representation of watersheds, overland flow routing, and channel flow routing.

In a powerful work of environmental history, Martin Doyle tells the epic story of America and its rivers, from the U.S. Constitution's roots in interstate river navigation, to the failure of the levees in Hurricane Katrina and the water wars in the west. Through his own travels and his encounters with experts all over the country-a Mississippi River tugboat captain, an Erie Canal lock operator, a project manager buying water rights for farms along the Colorado River-Doyle reveals the central role rivers have played in American history and how vital they are to its future.

Water resources and services are integrated measures of social systems that range beyond the technical world and the IWRM requires a balance between competing views of social and political issues. This volume focuses on increased awareness of the human dimension, women's role, environmental protection, sustainability and food security aspects in achieving sustainable water management. Understanding the strategies used by small farmers, as well as how small farming systems work or why they fail, could shed light on the constraints they face and the measures to be taken to overcome them. It also draws key insights on movements promoting the involvement of grassroots communities in the sustainable management of their resources.

Water is a key driver of economic and social development while it also has a basic function in maintaining the integrity of the natural environment. Presents the rationale approach for the Integrated Water Resources Management; this volume brings together both the different environmental problems that affect the very different ecosystems and the main methodologies able to face the problem of IWM. It will be of an invaluable resource for those involved in urban water management, including water utility managers, engineering technical staff, operations and maintenance specialists.

This report contains the findings from a rapid biological assessment of the Grensgebergte and Kasikasima mountains of southeastern Suriname. Suriname is one of the last places on Earth where an opportunity still exists to conserve huge tracts of pristine, diverse tropical forests. This volume is part of a series of surveys in Suriname designed to support the protection of biodiversity and freshwater and other ecosystem services through collection of baseline biological and socioeconomic data. The researchers in southeastern Suriname investigated plants, mammals, birds, reptiles, amphibians, fishes, insects, and water quality. Over one hundred new species were discovered, including fish, beetles, and katydids.

In 1992 landmark federal legislation called for the removal of two dams from the Elwha River to restore salmon runs. Jeff Crane dives into the debate over development and ecological preservation in "Finding the River, " presenting a long-term environmental and human history of the river as well as a unique look at river reconstruction.

"Finding the River" examines the ways that different communities--from the Lower Elwha Klallam Indians to current-day residents--have used the river and its resources, giving close attention to the harnessing of the Elwha for hydroelectric production and the resulting decline of its fisheries. Jeff Crane describes efforts begun in the 1980s to remove the dams and restore the salmon. He explores the rise of a river restoration movement in the late twentieth century and the roles that free-flowing rivers could play in preserving salmon as global warming presents another set of threats to these endangered fish.

A significant and timely contribution to American Western and environmental history--removal of the two Elwha River dams is scheduled to begin in September 2011--"Finding the River" will be of interest to historians, to environmentalists, and to fisheries biologists, as well as to general readers interested in the Puget Sound and Olympic Peninsula and environmental issues

Guitard's photographs are composed with an eye to the diversity and particular beauty and geological situation of each watercourse. A map locates each waterfall. Spanning all five regions of New Brunswick (Acadian Coastal, Appalachian Range, River Valley Scenic, Fundy Coastal, and Miramichi River), there's something for everyone -- you may even want to strap on your backpack and head out to experience them yourself.

Since the 1950s,the International Joint Commission (IJC) of Canada and the United States has issued water regulation and management plans for Lake Ontario and the St. Lawrence River. Changes in recreational, environmental, navigational and other uses of the water system have prompted the IJC to consider replacing the current water regulation plan in operation for more than 40 years. IJC's goals for a replacement plan include sound scientific foundations, public participation, transparency in plan development and evaluation, and inclusion of environmental considerations. To help develop and select the new plan, the IJC supported a 5-year, $20 million Lake Ontario-St. Lawrence River Study (LOSLR Study). The LOSLR Study uses models to compile and integrate data gathered from a series of commissioned studies of wetlands, species at risk, recreational boating, fisheries, coastal erosion and flooding, commercial navigation, hydropower, industrial, municipal and domestic water intakes, public information and education, and hydrologic modeling. This report reviews a portion of the study that focused on wetlands and species at risk and three of the models that were used. The report finds that the overall breadth of the LOSLR study is impressive, and commends the scale and inclusiveness of the studies and models. In terms of informing decision making, however, the reviewed studies and models show deficiencies when evaluated against ten evaluation criteria, including treatment of uncertainty, quality control/quality assurance, thorough documentation, and empirical foundations. Among the report's recommendations is a need for more thorough documentation of study methods and findings, stronger and more consistent quality control, and more attention to how uncertainty should be addressed to better inform decision making. This NRC study was conducted in collaboration with the Royal Society of Canada.

From warning the public of impending floods to settling legal arguments over water rights, the measurement of streamflow ("streamgaging") plays a vital role in our society. Having good information about how much water is moving through our streams helps provide citizens with drinking water during droughts, control water pollution, and protect wildlife along our stream corridors. The U.S. Geological Survey's (USGS) streamgaging program provides such information to a wide variety of users interested in human safety, recreation, water quality, habitat, industry, agriculture, and other topics. For regional and national scale streamflow information needs, the USGS has created a National Streamflow Information Program (NSIP). In addition to streamgaging, the USGS envisions intensive data collection during floods and droughts, national assessments of streamflow characteristics, enhanced information delivery, and methods development and research. The overall goals of the program are to: meet legal and treaty obligations on interstate and international waters, support flow forecasting; measure river basin outflows, monitor sentinel watersheds for long-term trends in natural flows, and measure flows for water quality needs. But are these the right topics to collect data on? Or is the USGS on the wrong track? In general, the book is supportive of the design and content of NSIP, including its goals and methodology for choosing stream gages for inclusion in the program. It sees the ultimate goal of NSIP as developing the ability to use existing data-gathering sites to generate streamflow information with quantitative confidence limits at any location in the nation. It is just as important to have good measurements during droughts as during floods, and it therefore recommends supporting Natural Resource Conservation Service forecast sites in addition to those of the National Weather Service.
