The Oak Ridge National Laboratory's Environmental Sciences Division initiated the Walker Branch Watershed Project on the Oak Ridge Reservation in east Tennessee in 1967, with the support of the U. S. Department of Energy's Office of Health and Environmental Research (DOE/OHER), to quantify land-water interactions in a forested landscape. It was designed to focus on three principal objectives: (1) to develop baseline data on unpolluted ecosystems, (2) to contribute to our knowledge of cycling and loss of chemical elements in natural ecosystems, and (3) to provide the understanding necessary for the construction of mathe matical simulation models for predicting the effects of man's activities on forested landscapes. In 1969, the International Biological Program's Eastern Deciduous Forest Biome Project was initiated, and Walker Branch Watershed was chosen as one of several sites for intensive research on nutrient cycling and biological productivity. This work was supported by the National Science Foundation (NSF). Over the next 4 years, intensive process-level research on primary productivity, decomposition, and belowground biological processes was coupled with ongoing DOE-supported work on the characterization of basic geology and hydrological cycles on the watershed. In 1974, the NSF's RANN Program (Research Applied to National Needs) began work on trace element cycling on Walker Branch Wa tershed because of the extensive data base being developed under both DOE and NSF support.

This book provides updated and comprehensive information on the evaluation of the river basin environment, along with its management and conservation. The chapters collected the latest cutting-edge research achievements in vegetation function evaluation, remote sensing monitoring and analysis, water quality evaluation and control, water and wastewater treatment, soil remediation, forest resource management, microbial disease diagnosis and more, the key components that link directly with the safety, security and sustainability of river basin environment. This book emphasizes the important aspects for better and more effective evaluation, management and conservation of the river basin environment, the foundation for its sustainable utilization and development, the foundation for achieving water and food security, and the United Nations’ SDGs for No Poverty (1), Zero Hunger (2) and Clean Water and Sanitation (6), as well as Affordable and Clean Energy (7), Sustainable Cities and Communities (11), Climate Action (13), Life below Water (14) and Life on Land (15). This book will benefit the research community and environmental education. It will prove useful to students, water and forest resource managers, hydrologists and all those engaged or interested in any aspect of evaluation, management, and conservation of the river basin environment. The book also has the potential to inform multi-regional and sectoral policies in all regions of the world and contribute to sustainable development solutions through better management of water, soil, and vegetation resources.

Large-scale experimentation allows scientists to test the specific responses of ecosystems to changing environmental conditions. Researchers at Oak Ridge National Laboratory together with other Federal and University scientists conducted a large-scale climatic change experiment at the Walker Branch Watershed in Tennessee, a model upland hardwood forest in North America. This volume synthesizes mechanisms of forest ecosystem response to changing hydrologic budgets associated with climatic change drivers. The authors explain the implications of changes at both the plant and stand levels, and they extrapolate the data to ecosystem-level responses, such as changes in nutrient cycling, biodiversity and carbon sequestration. In analyzing data, they also discuss similarities and differences with other temperate deciduous forests. Source data for the experiment has been archived by the authors in the U.S. Department of Energy's Carbon Dioxide Information and Analysis Center (CDIAC) for future analysis and modeling by independent investigators.
