Synopsis

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.

A propos du livre

Présentation de l'éditeur

This book presents a summary and synthesis of two decades of research on biogeochemical cycling and related processes in Walker Branch Watershed, a mixed deciduous watershed near Oak Ridge, Tennessee, which is one of only a few long-term, intensive ecosystem studies in the United States aimed at the quantification of land-water interactions in a forested landscape. In addition to a comprehensive site description, the book pulls together for the first time results from this study in the areas of forest meteorology, atmospheric deposition, hydrology, carbon dynamics and productivity, terrestrial nutrient cycling, stream chemistry and ecology, and mathematical modeling. The data sets obtained allow extrapolation to eastern deciduous forests in general and provide scientists and environmental managers with baselines against which future changes in forest ecosystem composition and behavior may be assessed. Researchers and professionals in environmental sciences will be interested in how these results compare and contrast with those of other major watershed studies. Students will especially appreciate the text as a well-rounded case study of watershed scale analysis.
