Download or read book Wetlands: Ecosystem Services, Restoration and Wise Use written by Shuqing An and published by Springer. This book was released on 2019-07-04 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores major wetland ecosystem services, such as climate cooling and water quality improvement, and discusses the recent wetland conservation and restoration activities in China and neighboring countries. The role of wetlands in either cooling or warming the climate is analyzed as the net balance between carbon sequestration and emissions of methane and nitrous oxide. Wetlands start off having a net warming effect on the climate but in time switch to net cooling. Further, they remove 40% of the N and P from run-off and groundwater flow in agricultural areas, but wetlands need to amount to 10% of the total catchment area to make a difference. Reflecting on the recent large investment in wetland ecological studies in China and neighboring countries, the book addresses invasive species in coastal wetlands as well as the protection and wise use of tidal flats around the Yellow Sea. It also presents promising regional case studies on wetland restoration. The book is intended for academics, students and practitioners in the field of wetland ecology, management and restoration, as well as consultants and professionals working in conservation, wise use and environmental policy.

Download or read book Five Hydrologic Studies written by and published by . This book was released on 2005 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The U.S. Department of Agriculture Forest Service Center for Forested Wetlands Research has conducted or cooperated in studies designed to improve understanding of fundamental hydrologic and biogeochemical processes that link aquatic and terrestrial ecosystems. Five of these studies are discussed here. The first is based on observations made on long-term experimental watersheds established in the 1960s on the Forest Service Santee Experimental Forest in South Carolina. It quantifies the soil moisture dynamics, flow regimes, and water chemistry of low-gradient forested wetlands. The second study is being conducted in cooperation with North Carolina State University. It is a long-term project aimed at quantifying the effects of various water management and silvicultural management practices on hydrology and water quality at the Weyerhaeuser Company's managed pine forest in Carteret County, North Carolina. The third study is a long-term ecosystem study on MeadWestvaco's Coosawhatchie River bottomland hardwood site in South Carolina. It addresses questions related to public concerns about the need for protection, restoration, and sustainable management of forested wetlands. The fourth study, which was conducted between 1997 and 2000, examined the hydrology and water quality of intensively managed short-rotation woody crop plantations on International Paper's Trice experimental forest in the upper Coastal Plain of South Carolina. A fifth study was conducted between 1996 and 2004 at MeadWestvaco's Carolina bay site in the South Carolina upper Coastal Plain; it assessed the surface-water and ground-water interactions between Carolina bays and their surrounding uplands. Recommendations are provided for using knowledge gained through these and other studies as a basis for expanding needed hydrologic research with collaborators to address four major areas of water-related issues in the Southeast."--P.

Download or read book Climate Change Adaptation and Mitigation Management Options written by James M. Vose and published by CRC Press. This book was released on 2013-12-05 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Download or read book Statistical Methods in Water Resources written by D.R. Helsel and published by Elsevier. This book was released on 1993-03-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Download or read book Predicting the Runoff from Storm Rainfall written by Max Adam Kohler and published by . This book was released on 1951 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimation of the volume of runoff to be expected from a given volume of rainfall is a fundamental problem in flood forecasting. Such estimates are necessary before the unit hydrograph or other techniques can be used to predict the streamflow hydrograph. The authors describe the technique now used at the River Forecast Centers of the U.S. Weather Bureau for evaluating the effect of season, antecedent conditions, duration of rainfall and rainfall amount in determining the portion of the rainfall contributing to storm runoff. Special problems encountered in flood forecasting are emphasized. The technique, developed and tested over several years, yields a high degree of accuracy in estimated runoff. Although prepared by empirical procedures, the close agreement between relations for basins of similar hydrologic characteristics suggests that rational parameter have been adopted. The similarity between relations also simplifies the work required for their preparation.

Download or read book Achieving Nutrient and Sediment Reduction Goals in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2011-09-26 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.

Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 57. Every time it rains, biologically active nitrogen compounds are transferred from the air to whatever surface lies underneath; what a farmer once called "the poor man's fertilizer." In fact, nitrogen containing compounds are transferred between surface and atmosphere even when it is not raining. That this atmospheric nitrogen deposition impacts on the environment is a scientifically accepted fact, established during the acid rain debates led by the National Acid Precipitation Assessment Program. The extent to which this deposition contributes to the decline of coastal waters around the United States due to over fertilization, however, is still under debate. In response to and as a continuation of this debate is the current work before you: the first attempt to consistently and comprehensively estimate the relative contribution of atmospherically delivered nitrogen to the total amount of nitrogen entering coastal estuaries around the United States.
