This book was released on 2009-03-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-site treatment of wastewater at highway rest areas poses some unique and difficult challenges because of the rural locale, high variability in wastewater flow rate and strength, and lack of knowledgeable personnel on-site. As a potential alternative, a constructed subsurface wetland system was built at the I-70 rest stop nearby Greenfield, Indiana, in 2003. This wetland system, mainly composed of three wetland cells, also includes draw-and-fill and recirculation mechanisms to increase oxygen transfer to the wastewater and improve the overall treatment performance. Special considerations for highway rest areas have been emphasized. A dynamic hydraulic model was developed to help characterize the flows in the system and estimate the hydraulic retention time. The size of the Greenfield wetland was found to be sufficient in providing pretreatment that could help avoid potential surcharge from the local treatment plant, but was inadequate for direct onsite discharge. Though the draw-and-fill and recirculation mechanisms provided some treatment benefits, they raised the construction costs and maintenance needs. Constructed wetlands have been described as low-maintenance systems compared to other conventional wastewater treatment approaches, but proper maintenance of the wetland facilities was found to be a key factor in achieving good performance. Since wetland systems in highway rest areas have not been studied, this study provided useful information for possible future implementation of such systems.

This book was released on 1980 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of growing interest in the role of lakes and wetlands in the hydrology of the prairie environment, a group of wetlands in the Cottonwood Lake area, Stutsman County, N. Dak., are being instrumented for long-term hydrologic studies. The study site is on a regional topographic high near the eastern edge of the Missouri Coteau and is underlain by more than 400 feet of glacial drift, largely silty, clayey till. Long-term climatic data indicate the study area is in a water deficient area--mean annual evaporation exceeds mean annual precipitation by about 18 inches. Different methodologies are being used to compare measurements and estimates of each hydrologic component interacting with the lakes and wetlands. For example, for a 3-month period in 1979, estimates of precipitation for the study site using data collected at National Weather Service stations differed from that measured by a recording gage at the study site by several tenths of an inch for 14-day totals and differed by more than half an inch for individual storms. Numerical simulation analysis of regional groundwater flow systems shows the study site is situated in a regional recharge area, but local groundwater flow systems can discharge to lakes and wetlands within the recharge area. Instrumentation at the study site shows a complex interrelation of wetlands and groundwater. Based on data for 1979 only, some wetlands appear to recharge groundwater, some wetlands are flow-through types where groundwater enters one side and surface water seeps to groundwater on the other side, and some wetlands are discharge points for groundwater. Further, these interrelations vary throughout the year.

Available in PDF, EPUB and Kindle. Book excerpt: "Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committeeâ€"whose members were drawn from academia, government, business, and the environmental communityâ€"builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Practical Handbook for Wetland Identification and Delineation written by John G. Lyon and published by CRC Press. This book was released on 1993-03-25 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this time of concern over wetlands, many groups have compelling reasons to identify and delineate wetlands. Financial institutions use environmental evaluation as a part of their loan decisions. Civil engineers must plan sites without disturbing existing wetlands. Conservation groups wish to identify valuable wetlands for preserves or parks. Local and state governments need wetlands assessments for management and planning of existing and future public lands. And the Federal government has mandated that wetlands receive more attention. As our understanding of wetlands functions increases, the ability to identify and delineate them becomes even more critical. Practical Handbook for Wetland Identification and Delineation defines wetlands, describes their functions, and presents a variety of methods used to assess the extent of wetlands. Easy-to-use, it offers solutions to real-world problems and covers important subjects such as methods for identifying and delineating wetland boundaries, evaluating wetlands using aerial photography, indicators of hydrological, chemical, and biological processes, soil surveys, and plant measurements. The book also discusses methodological approaches to optimizing wetland delineation and permitting. The focus on wetlands by the Federal government has resulted in more stringent oversight by the U.S. Army Core of Engineers (USACE). This new level of federal oversight has underlined the lack of general knowledge related to regulatory requirements. Project delay and work interruptions are real, potential problems for landowners. Practical Handbook for Wetlands Identification and Delineation presents the strategies and methods for making wetlands identifications and delineations that meet federal requirements.

This book was released on 2010-01-01 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands and riparian areas between the Rocky Mountains and the Sierra Nevada are incredibly diverse and valuable habitats. More than 80 percent of the wildlife species in this intermountain region depend on these wetlands—which account for less than 2 percent of the land area—for their survival. At the same time, the wetlands also serve the water needs of ranchers and farmers, recreationists, vacation communities, and cities. It is no exaggeration to call water the "liquid gold" of the West, and the burgeoning human demands on this scarce resource make it imperative to understand and properly manage the wetlands and riverine areas of the Intermountain West. This book offers land managers, biologists, and research scientists a state-of-the-art survey of the ecology and management practices of wetland and riparian areas in the Intermountain West. Twelve articles examine such diverse issues as laws and regulations affecting these habitats, the unique physiographic features of the region, the importance of wetlands and riparian areas to fish, wildlife, and livestock, the ecological function of these areas, their value to humans, and the methods to evaluate these habitats. The authors also address the human impacts on the land from urban and suburban development, mining, grazing, energy extraction, recreation, water diversions, and timber harvesting and suggest ways to mitigate such impacts.
