At A Watershed

In June 2008, the rivers of eastern Iowa rose above their banks to create floods of epic proportions; their amazing size—flowing in places at a rate nearly double that of the previous record flood—and the rapidity of their rise ruined farmlands and displaced thousands of residents and hundreds of businesses. In Cedar Rapids, the waters inundated more than nine square miles of the downtown area; in Iowa City, where the flood was also the most destructive in history, the University of Iowa’s arts campus was destroyed. By providing a solid base of scientific and technical information presented with unusual clarity and a wealth of supporting illustrations, the contributors to this far-reaching book, many of whom dealt firsthand with the 2008 floods, provide a detailed roadmap of the causes and effects of future devastating floods. The twenty-five essays fall naturally into four sections. “Rising Rivers, Spreading Waters” begins by comparing the 2008 floods with the midwestern floods of 1993, moves on to trace community responses to the 2008 floods, and ends by illuminating techniques for forecasting floods and determining their size and frequency. “Why Here, Why Now?” searches for possible causes of the 2008 floods and of flooding in general: annual crops and urban landscapes, inflows into and releases from reservoirs, and climate change. “Flood Damages, Flood Costs, Flood Benefits” considers the complex mix of flood costs and effects, emphasizing damages to cities and farmlands as well as potential benefits to natural communities and archaeological sites. “Looking Back, Looking Forward” lays out approaches to managing the floods of the future that are sure to come. While the book draws most of its examples from one particular region, it explains flooding throughout a much larger region—the midwestern Corn Belt—and thus its sobering yet energizing lessons apply well beyond eastern Iowa. By examining the relationships among rivers, floodplains, weather, and modern society; by stressing matters of science and fact rather than social or policy issues; and by addressing multiple environmental problems and benefits, A Watershed Year informs and educates all those who experienced the 2008 floods and all those concerned with the larger causes of flooding.

Entering the Watershed is the product of a two-year project established by the Pacific Rivers Council to develop new federal riverine protection and restoration policy alternatives. It recommends a comprehensive new approach to river protection based on principles of watershed dynamics, ecosystem function, and conservation biology -- a nationwide, strategic community- and ecosystem-based watershed restoration initiative. The book: describes in detail the existing level of damage to rivers and species analyzes flaws and gaps in existing policy provides the framework necessary to develop new policies outlines the scientific underpinnings and management strategies needed in new policy makes specific policy proposals

Thinking Like a Watershed points our understanding of our relationship to the land in new directions. It is shaped by the bioregional visions of the great explorer John Wesley Powell, who articulated the notion that the arid American West should be seen as a mosaic of watersheds, and the pioneering ecologist Aldo Leopold, who put forward the concept of bringing conscience to bear within the realm of "the land ethic." Produced in conjunction with the documentary radio series entitled Watersheds as Commons, this book comprises essays and interviews from a diverse group of southwesterners including members of Tewa, Tohono O'odham, Hopi, Navajo, Hispano, and Anglo cultures. Their varied cultural perspectives are shaped by consciousness and resilience through having successfully endured the aridity and harshness of southwestern environments over time.

Integrated Approaches to Sustainable Watershed Management in Xeric Environments: A Training Manual provides the reader with the tools they need to understand an integrated approach to watershed management. The book presents a conceptual framework of water management based on the authors’ vast experience. Topics covered include a scientific background of watershed management and the integration of geohydraulic and socioeconomic factors. Key points are further enhanced with case studies, problem sets, Bayesian Networks and quizzes to educate watershed managers, industry professionals and agencies. Authored by a team of leaders in the field who are responsible for groundbreaking research in the area, this book draws on their experience synthesizing scientific, practical, on the ground expertise. This is an essential tool for researchers and professionals in environmental, water or natural resource management. Presents an integrated approach—combining different sciences— that allows for the improved design of watersheds through the integration of biophysical, land use and socioeconomic analyses Contains activities for self-evaluation Includes case studies drawing from field experiences, giving the reader deeper insights into challenges faced, practical problems and solutions

In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.
