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.

This book was released on 1976 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a sedimentation study, forming part of an assessment of environmental impacts associated with in-lake disposal of dredge spoil on Lake Superior. This assessment was requested by the St. Paul District Office of the US Corps of Engineers and funded under contract number DACW37-74-C-0013 to the University of Wisconsin-Madison in August, 1973. Field and laboratory studies focused on two locations where a substantial amount of dredging is done annually: Duluth-Superior and the Keweenaw Waterway.

Book excerpt: This project was funded by the Corps of Engineers to study effects of in-lake dredge spoil disposal on toxicity and availability of heavy metals to the biota of Lake Superior. Attention was focused on the benthic organisms in direct contact with the sediment. In the laboratory sublethal bioassays were used to examine effects of mercury and zinc contaminated sediments on the burrowing scud, Pontoporeia affinis. This amphipod is the predominant benthic invertebrate in Lake Superior and a major food base for Lake Superior fishes. Changes were observed in locomotor activity of Pontoporeia as a measure of their health on sediments with and without added mercury and zinc, and whole body concentrations of these metals were measured in Pontoporeia after exposure to the enriched sediments for periods of two days to two weeks. The benthic communities near Duluth-Superior were surveyed and maps showing distribution and abundance of organisms were prepared. Samples were collected for background levels of various elements in sediments, invertebrates, and fish in Lake Superior. Shorebird populations were surveyed at Duluth-Superior and the Keweenaw Peninsula. The authors also worked with scientists at Michigan Technological University to obtain similar information for the Corps of Engineers at the Keweenaw Waterway and adjacent Lake Superior.
