Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to provide a physical and ecological analysis of paired watersheds in the semi-arid western juniper (Juniperus occidentalis) woodlands of Central Oregon. Instrumentation and monitoring was accomplished in Jensen and Mays watersheds as the preliminary portion of a longer term project. Instrumentation was designed to address changes in the erosional processes, hydrology, and vegetation on a watershed scale. Instrumentation was setup to assist in the comparison and calibration of water flow out of the watersheds. This information will be used in the long-term study in conjunction with the treatment of the western juniper overstory on one of the watersheds. Determination of the study area in each watershed required extensive reconnaissance with the assistance of aerial photos, topographic maps, and Geographic Information Systems (GIS). Mapping of the study areas was accomplished with GIS and Global Positioning Systems (GPS). Watersheds were paired according to specific characteristics that influence treatment effects. Flume types were chosen with respect to precipitation intensity and frequency with placement being more a function of watershed topography and channel morphology. Upland sedimentation and erosion measurement required intense acknowledgement of both abiotic as well as biotic characteristics. Analysis showed the watersheds to be similar in size, percent juniper, grass and bare soil cover, topography, and precipitation frequency and intensity. Differences were obtained relative to erosional processes, area of different soil types and channel discharge. Further monitoring and calibration should provide greater insight into the comparison of these components of the study.

This book was released on 2007-12-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-06-29 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bear Brook Watershed in Maine (BBWM) is a long-term, whole-watershed study examining the effects of experimentally elevated N and S deposition on a treated watershed, in comparison to the adjacent reference watershed. The study is in a northern New England, USA, forested ecosystem, and focuses on soil and stream hydrological and biogeochemical processes, and chemical responses of vegetation. Relative to the reference watershed, the treated ecosystem has migrated biogeochemically towards N saturation, and soil and stream acidification. Some of the responses to N amendments were not expected nor predicted by available models.

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume contains papers and extended abstracts presented at the International Conference on Sustainable Watershed Management (SuWaMa 2014). The Conference was the second in a series of Sustainable Watershed Management Conferences. The objective of the Conference Series was to present and discuss advanced environmental models and contemporary decision support tools for the sustainable use and development of watersheds. Contributions cover the following topics: sound watershed management practices (case studies and examples from various countries including lessons learned from implementation of both successful and deficient management scenarios), decision support tools (such as monitoring, GIS, ecological economics, cost/benefit analysis and decision making models), integrated environmental model applications for management (including watershed, air-shed, coastal, and living resource models), trans-boundary environmental issues (air pollution, climate change, coastal oceans at regional, continental, and global scales) and global watershed sustainability. This multidisciplinary volume will benefit natural and social scientists, engineers, managers and other professionals as well as stakeholders with an interest in water resources and their management.

This book was released on 2021-04-07 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the challenges of sustaining long-term ecological research through a historical analysis of the Long Term Ecological Research Program created by the U.S. National Science Foundation in 1980. The book examines reasons for the creation of the Program, an overview of its 40-year history, and in-depth historical analysis of selected sites. Themes explored include the broader impact of this program on society, including its relevance to environmental policy and understanding global climate change, the challenge of extending ecosystem ecology into urban environments, and links to creative arts and humanities projects. A major theme is the evolution of a new type of network science, involving comparative studies, innovation in information management, creation of socio-ecological frameworks, development of governance structures, and formation of an International Long Term Ecological Research Network with worldwide reach. The book’s themes will interest historians, philosophers and social scientists interested in ecological and environmental sciences, as well as researchers across many disciplines who are involved in long-term ecological research.
Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Pilot Watershed Study is a major sub-program of the Soil & Water Environmental Enhancement Program, aimed at evaluating & demonstrating the benefits of established conservation farming systems at the watershed & smaller scales. The study design relies on direct comparisons between test & control watersheds as the primary method of environmental & agronomic evaluation. This report documents the process in which three pairs of agricultural watersheds in the Lake Erie drainage basin were selected to represent different landscapes with commonly applied conventional farming practices and a farming community open to the adoption of conservation farming systems. It compiles physical & social information on these watersheds to allow for subsequent agronomic & environmental analysis, and monitored meteorological parameters which affect crop performance and watershed hydrology & erosion-transport processes.
