Physical and chemical environmental parameters were monitored to describe soil and plant characteristics on an artificially disturbed forest soil in the wester Sierra Nevada Mountains. USFS Long Term Soil Productivity Research Program disturbance treatments were assessed in order to characterize the impacts of forest removal, soil compaction and the removal of organic residue on soil moisture characteristics and related physiological processes as related to soil water uptake and site hydrology. The effects of forest removal and soil compaction on Cohasset soils have consistently shown increased levels in soil moisture content and reduced soil water potential especially when the effects are combined. The present investigation demonstrates that on Cohasset soils, volcanically derived fine-textured clayey soils, disturbance of soil structure and soil structure-related water availability can contribute to physiological stress in Pinus ponderosa and significantly alter site hydrology.

This work advises owners and managers how woodlands and forests influence the freshwater ecosystem, and gives guidance on how operations should be carried out in order to protect and enhance the water environment. The guidelines apply equally to forest enterprises and the private sector.

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 United Nations has declared 2018-2028 as the International Decade for Action on Water for Sustainable Development. This is a timely designation. In an increasingly thirsty world, the subject of forest-water interactions is of critical importance to the achievement of sustainability goals. The central underlying tenet of this book is that the hydrologic community can conduct better science and make a more meaningful impact to the world’s water crisis if scientists are: (1) better equipped to utilize new methods and harness big data from either or both high-frequency sensors and long-term research watersheds; and (2) aware of new developments in our process-based understanding of the hydrological cycle in both natural and urban settings. Accordingly, this forward-looking book delves into forest-water interactions from multiple methodological, statistical, and process-based perspectives (with some chapters featuring data sets and open-source R code), concluding with a chapter on future forest hydrology under global change. Thus, this book describes the opportunities of convergence in high-frequency sensing, big data, and open source software to catalyze more comprehensive understanding of forest-water interactions. The book will be of interest to researchers, graduate students, and advanced undergraduates in an array of disciplines, including hydrology, forestry, ecology, botany, and environmental engineering.

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.

It has become clear that soil water repellency is much more wide-spread than formerly thought. Water repellency has been reported in most continents of the world for varying land uses and climatic conditions. Soil water repellency often leads to severe runoff and erosion, rapid leaching of surface-applied agrichemicals, and losses of water and nutrient availability for crops. At present, no optimum management strategies exist for water repellent soils, focusing on minimizing environmental risks while maintaining crop production. The book starts with a historical overview of water repellency research, followed by seven thematic sections covering 26 research chapters. The first section discusses the origin, the second the assessment, and the third the occurrence and hydrological implications of soil water repellency. The fourth section is devoted to the effect of fire on water repellency, section five deals with the physics and modeling of flow and transport in water repellent soils, section six presents amelioration techniques and farming strategies to combat soil water repellency, and section seven concludes the book with an extensive bibliography on soil water repellency.
