Students and professors of hydrology, ecology, land-use management, forest and range management, soil science, physical geography, soil and water conservation, and watershed management will welcome this revision of the 1969 edition of An Outline of Forest Hydrology by John D. Hewlett and Wade L. Nutter. The student pursuing a career in forest and wildland resources soon learns that no science is more fundamental to the art of land management than hydrology, but hydrology as a science traditionally has been subordinated to hydrology as technique. Older texts have focused on methods and applications to the exclusion of principle, occasionally leaving the hydrological effects of land use and vegetation to be interpreted from techniques rather than from knowledge of process. Soil, atmospheric, and vegetal phases of the hydrologic cycle of have neglected in many texts intended for the college student. Hewlett’s new book focuses on natural processes and is intended to guide further study and to serve as a base for class lectures. The subject matter is organized to introduce key ideas and principles and to provide consistent terminology and clear graphic material to aid the student in comprehending the complex literature of hydrology.

Due to its height, density, and thickness of crown canopy; fluffy forest floor; large root system; and horizontal distribution; forest is the most distinguished type of vegetation on the earth. In the U.S., forests occupy about 30 percent of the total territory. Yet this 30 percent of land area produces about 60 percent of total surface runoff, the major water resource area of the country. Any human activity in forested areas will inevitably disturb forest floors and destroy forest canopies, consequently affecting the quantity, quality, and timing of water resources. Thoroughly updated and expanded, Forest Hydrology: An Introduction to Water and Forests, Third Edition discusses the concepts, principles, and processes of forest and forest activity impacts on the occurrence, distribution, and circulation of water and the aquatic environment. Brings water resources and forest-water relations into a single, comprehensive textbook Focuses on the concepts, processes, and general principles in forest hydrology Covers functions, properties, and science of water; water distribution; forests and precipitation, vaporization, stream flow, and stream sediment Discusses watershed management planning and practical applications of forest hydrology in resource management In a single textbook, Forest Hydrology: An Introduction to Water and Forests, Third Edition comprehensively covers water and water resources issues, forest characteristics relevant to the environment, forest impacts in the hydrological cycle, watershed research, watershed management planning, and hydrologic measurements. With the addition of new chapters, new issues, and appendices, this new edition is a valuable resource for upper-level undergraduates in forest hydrology courses as well as professionals involved in water resources management and decision-making in forested watersheds.

Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

For the last three centuries forests have been recognised as providing the best water catchments and valued for their sustained output of high quality water. In Australia, work which was commenced fifty years ago has come to fruition and is providing new information on forest hydrology issues. The book focusses on the issues of small streams, including catchment definition, slope, hydrograph formation, water quality measurement, and annual water yield. The world-wide management issues of sustaining riparian forests are examined, using the River Murray forests as an example. Finally a large amount of information is drawn together to examine the management of forested catchments for water supplies. This book presents an incisive, disciplined, quantitative approach to dealing with forest hydrology matters. Although world-wide in application, the book particularly draws on Australian studies. It is written with the needs of students and forest practitioners in mind.

Of all the outputs of forests, water may be the most important. Streamflow from forests provides two-thirds of the nation's clean water supply. Removing forest cover accelerates the rate that precipitation becomes streamflow; therefore, in some areas, cutting trees causes a temporary increase in the volume of water flowing downstream. This effect has spurred political pressure to cut trees to increase water supply, especially in western states where population is rising. However, cutting trees for water gains is not sustainable: increases in flow rate and volume are typically short-lived, and the practice can ultimately degrade water quality and increase vulnerability to flooding. Forest hydrology, the study of how water flows through forests, can help illuminate the connections between forests and water, but it must advance if it is to deal with today's complexities, including climate change, wildfires, and changing patterns of development and ownership. This book identifies actions that scientists, forest and water managers, and citizens can take to help sustain water resources from forests.

The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today’s pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970’s studies of atmospheric deposition; the 1980’s research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990’s investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century’s research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who’s who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.

The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

Forest management is a complex process that now incorporates information obtained from many sources. It is increasingly obvious that the physiological status of the trees in a forest has a dramatic impact on the likely success of any particular management strategy. Indeed, models described in this book that deal with forest productivity and sustainability require physiological information. This information can only be obtained from an understanding of the basic biological mechanisms and processes that contribute to individual tree growth. This valuable book illustrates that physiological ecology is a fundamental element of proficient forest management. Provides essential information relevant to the continuing debate over sustainable forest management Outlines how modern tools for physiological ecology can be used in planning and managing forest ecosystems Reviews the most commonly used forest models and assesses their value and future
