Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to prepare a comprehensive review of the literature on the physical, chemical, and biological effects of dredging and spoil disposal in estuaries and to identify alternative spoil disposal methods. Specific objectives were to identify the most critical problems relating to dredging and spoil disposal and to summarize the progress made to date in solving these problems. Using literature search facilities, bibliographies, and communications with experts throughout the United States, about 520 scientific and technical articles on dredging and spoil disposal were screened. Information extracted from selected articles is included in this review.

Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental ob jective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other in dividual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

This book was released on 2012-12-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Joint Commission (IJC) was established between Canada and the United States under the Boundary Water Agreement in 1909. The Great Lakes Water Quality Agreement between the two countries (signed in 1972, revised and renewed in 1978) expresses the determination of each country to restore and en hance the water quality of the largest freshwater system in the world. The Agreement provides for two inter national boards to assist the IJC: the Great Lakes Water Quality Board and the Great Lakes Science Advisory Board. In 1982, the Dredging Subcommittee of the Great Lakes Water Quality Board was asked to investigate and provide an assessment of the environmental impacts of sediment-bound contaminants and to recom mend alternate strategies for solving ecological problems associated with the presence and removal of pollu tants. This issue however, was beyond the scope of the Dredging Subcommittee. It was then referred to the Great Lakes Science Advisory Board with a specific request that the Board focus on whether contaminated sediments located in areas with water quality problems and impaired uses should be removed and if so, under what conditions. The Science Advisory Board established a Task Force to address these issues with specific reference to: - provide the IJC with an assessment of the effects of sediment-bound contaminants on biota and water quality; - recommend appropriate remedies for possible application by the parties for remedial activities in the Great Lakes; and - identify gaps in knowledge and suggest appropriate investigations to provide this knowledge.

This book was released on 1978 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nine dredged material land containment areas, located at upland, lowland, and island sites, were monitored during hydraulic dredging operations in fresh- and brackish-water riverine, lake, and estuarine environments. Influent-effluent sampling at the diked disposal areas showed that, with proper retention of suspended solids, most chemical constituents could be removed to near or below background water levels. Most heavy metals, oil and grease, chlorinated pesticides, and PCB's were almost totally associated with solids in both the influent and effluent samples. The only chemical parameters which failed to show average decreases of less than 90 percent in total effluent samples include: titanium (89 percent), manganese (88 percent), potassium (78 percent), magnesium (64 percent), ammonium nitrogen (57 percent), mercury (46 percent), op DDE (46 percent), and pp DDE (21 percent). Effluent mercury and titanium frequently appeared to be mainly associated with
