This fully revised edition provides a modern overview of the intersection of hydrology, water quality, and water management at the rural-urban interface. The book explores the ecosystem services available in wetlands, natural channels and ponds/lakes. As in the first edition, Part I examines the hydrologic cycle by providing strategies for quantifying each component: rainfall (with NOAH 14), infiltration, evapotranspiration and runoff. Part II examines field and farm scale water quality with an introduction to erosion prediction and water quality. Part III provides a concise examination of water management on the field and farm scale, emphasizing channel design, field control structures, measurement structures, groundwater processes and irrigation principles. Part IV then concludes the text with a treatment of basin-scale processes. A comprehensive suite of software tools is available for download, consisting of Excel spreadsheets, with some public domain models such as HY-8 culvert design, and software with public domain readers such as Mathematica, Maple and TK solver.

More than half of America's waterbodies are unsafe for swimming, fishing, and as sources of drinking. Why? Because of unsustainable city building and poor farming practice. Beyond water quality problems, dysfunctional streams cause flooding and erosion of property, leading to neighbourhood blights. Not only can this be reversed, but repair of degraded urban streams can be a powerful agent for reinventing the physical environments of post-industrial cities. This requires trans-disciplinary collaboration between the fields of ecological engineering and urban design. The American city was uniquely premised on fusions of landscape and urbanism: a tradition with plenty of room for innovation. However, watershed plans remain data-and-policy-driven documents with a singular interest in repairing waterbodies. They have little to say about the city and urban design. Conversely, urban planning has not codified the value of healthy ecosystems within which cities are built. In this age of the Anthropocene, when most ecosystems are human-dominated, resilient urban design must account for biological processes. This book introduces watershed management into urban design with one simple demand: that every new development contribute to watershed stewardship, where infrastructure and building deliver ecological services in addition to urban services. The Conway Urban Watershed Framework Plan formulates a planning vocabulary for use among professionals and decision-makers to engage this new design market.

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?

As with all large rivers in the United States, the Missouri River has been altered, with approximately one-third of the mainstem length impounded and one-third channelized. These physical alterations to the environment have affected the fish populations, but studies examining the effects of alterations have been localized and for short periods of time, thereby preventing generalization. In response to the U.S. Fish and Wildlife Service Biological Opinion, the U.S. Army Corps of Engineers (USACE) initiated monitoring of habitat improvements of the Missouri River in 2005.

The former chloralkali facility in Berlin, New Hampshire, was designated a Superfund site in 2005. Historic paper mill activities resulted in the contamination of groundwater, surface water, and sediments with many organic compounds and mercury (Hg). Hg continues to seep into the Androscoggin River in elemental form through bedrock fractures. The objective of this study was to spatially characterize (1) the extent of Hg contamination in water, sediment, and biota; (2) Hg speciation and methylmercury (MeHg) production potential rates in sediment; (3) the availability of inorganic divalent Hg (Hg(II)) for Hg(II)-methylation (MeHg production); and (4) ancillary sediment geochemistry necessary to better understand Hg speciation and MeHg production potential rates in this system.

Fish Creek, a tributary to the Snake River, is about 25 river kilometers long and is located in Teton County in western Wyoming near the town of Wilson. Public concern about nuisance growths of aquatic plants in Fish Creek have been increasing in recent years. To address this concern, the U.S. Geological Survey conducted a study in cooperation with the Teton Conservation District to characterize the water quality and biological communities in Fish Creek. Water-quality samples were collected for analyses of physical properties and water chemistry (nutrients, nitrate isotopes, and wastewater chemicals) between March 2007 and October 2008 from seven surface-water sites and three groundwater wells. During this same period, aquatic plant and macroinvertebrate samples were collected and habitat characteristics were measured at the surface-water sites.

The Copper River basin, with a damage area of 24,000 square miles is the sixth largest basin in Alaska.

A study of the Withlacoochee River watershed in west-central Florida was conducted from October 2003 to March 2007 to gain a better understanding of the hydrology and surface-water and groundwater interactions along the river. The Withlacoochee River originates in the Green Swamp area in north-central Polk County and flows northerly through seven counties, emptying into the Gulf of Mexico. This study includes only the part of the watershed located between the headwaters in the Green Swamp and the U.S. Geological Sur-vey gaging station near Holder, Florida. The Withlacoochee River within the study area is about 108 miles long and drains about 1,820 square miles.

The Santiam River is a tributary of the Williamette River in northwestern Oregon and drains an area of 1,810 aware miles. The U.S. Arm Corps of Engineers operates four dams in the basin, which are used primarily for flood control, hydropower production, recreation, and water-quality improvement.

The Umpqua River drains 12,103 km2 of western Oregon, heading in the Cascade Range and draining portions of the Klamath Mountains and Coast Range before entering the Pacific Ocean.

Well before quagga mussels were found in southern Nevada's Lake Mead in 2007, the Tahoe Regional Planning Agency (TRPA) and other federal agencies had prepared protective measures in case the mussels were detected west of the Continental Divide. Without examining the biological requirements of quagga mussels, the TRPA ignored dozens of scientific studies that showed quagga can't reproduce and survive in Lake Tahoe and implemented the nation's most aggressive watercraft inspection program. As water quality studies increasingly demonstrate that quagga can't survive in Lake Tahoe and its nearby lakes and reservoirs, the TRPA and their scientific partners have expanded the list of aquatic invasive species that could potentially infest Lake Tahoe. However, no reputable studies have been advanced that demonstrate that New Zealand mud snails, spiny water fleas, or hydrilla - the "new" organisms that boat inspections are protecting Tahoe from - can sustain in the lake. As the Town of Truckee considers whether to copy the five-year-old Lake Tahoe boat inspection program at Donner Lake, a draft edition of Tessie, Quagga Mussels, and Other Tahoe Myths has been given to the members of the Truckee Town Council and is made available to the public for their critical review. Publication of the marketed first edition will be withheld until the town council has had time to review the book and related material, and for those who may be critical of the book's science to comment. Documentation of factual errors and additional information are welcomed.

St. Clair River is a connecting channel that transports water from Lake Huron to the St. Clair River Delta and Lake St. Clair. A negative trend has been detected in differences between water levels on Lake Huron and Lake St. Clair. This trend may indicate a combination of flow and conveyance changes within St. Clair River. To identify where conveyance change may be taking place, eight water-level gaging stations along St. Clair River were selected to delimit seven reaches. Positive trends in water-level fall were detected in two reaches, and negative trends were detected in two other reaches.

The availability of abundant new borehole data from recent coal bed natural gas development was utilized by the U.S. Geological Survey for a comprehensive evaluation of coal resources and reserves in the southwestern part of the Powder River Basin in Wyoming. This report on the Southwestern Powder River Basin assessment area represents the third area within the basin to be assessed, the first being for coal resources and reserves in the Gillette coal field in 2008, and the second for coal resources and reserves in the northern Wyoming area of the basin in 2010.

In 2003, the National Park Service (NPS) at New River Gorge National River (NERI) hosted a workshop to identify significant forest issues, resources, and processes occurring within the park (National Park Service 2003b). Several forest communities of concern were identified by the panel of scientists and resource managers. One such community, the rimrock pine forest lining the rim of the gorge, was chosen due to the importance of the community to wildlife and recreation. The rimrock pines also were thought to be a historically significant feature of the northern section of the gorge as evidenced by historic photographs from the 1940s and 1950s. The panel suggested an investigation be conducted to better understand the establishment and maintenance of the rimrock pine forest.

The lands and waters of the Mid-Atlantic Region (MAR) have changed significantly since before the 16th century when the Susquehannock lived in the area. Much has changed since Captain John Smith penetrated the estuaries and rivers during the early 17th century; since the surveying of the Mason-Dixon Line to settle border disputes among Maryland, Pennsylvania, and Delaware during the middle of the 18th century; and since J. Thomas Scharf described the physiographic setting of Baltimore County in the late 19th century. As early as 1881, Scharf provides us with an assessment of the condition of the aquatic ecosystems of the region, albeit in narrative form, and already changes are taking place - the conversion of forests to fields, the founding of towns and cities, and the depletion of natural resources. We have always conducted our work with the premise that "man" is part of, and not apart from, this ecosystem and landscape. This premise, and the historical changes in our landscape, provide the foundation for our overarching research question: how do human activities impact the functioning of aquatic ecosystems and the ecosystem services that they provide, and how can we optimize this relationship?
