The U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency developed the elutritate test for the purpose of predicting the release of chemical contaminants from dredged sediments upon open-water disposal. This study was conducted to evaluate the factors influencing the results of the elutriate test and the reliability of this test in predicting the release of contaminants during actual open-water dredged material disposal operations. Sediment samples were taken from waterways...

Fire Island Inlet, NY, is an overlapping barrier inlet system, where the inlet channel lies on an east-west orientation with Fire Island to the south and east and Cedar Island and Jones Beach to the north and west. The main purpose of this study was to examine the response to inlet stabilization of inlet geomorphology and adjacent shoreline behavior over a time scale of decades. This study quantifies inlet migration, spit extension, and shoreline change in the areas surrounding Fire Island...

The Ala Wai canal is a small, man-made estuary that was dredged from August 2002 to October 2003 to increase water circulation and oxygen deficit in bottom waters. Rates of bacterial growth (heterotrophic production) and carbon metabolism (14C-substrate mineralization) were measured on surface sediments and core sections during three sampling events before, during, and after dredging. Heterotrophic production increased at all stations during the post-dredge sampling relative to the pre-dredge...

This report is one of two key integration tasks. Its purposes are to identify and evaluate alternative action strategies for meeting national water transportation needs. Water transportation needs have been determined by comparing forecasts of present and projected water transportation use with estimates of the present and future capability of the waterway system. Having determined water transportation needs, action strategies to meet these needs are identified and evaluated in this report....

Underwater construction tasks frequently require the removal of seafloor sand and sediment. An experimental sediment excavation tool was fabricated from commercially available and specially designed components. The diver-operated tool combined a jet-eductor, a jet nozzle, and a hydraulically powered sump pump into a jet-dredge tool to increase excavation rates, reduce reaction forces, and improve water visibility in jetting operations. A later version included multi-jet nozzles rather than a...

During the conduct of maintenance dredging in the Carolina Beach Inlet channel in the fall of 1983, the dredge Merritt, operated by the United States Army Engineer District, Wilmington, struck an obstruction. In order to locate the obstruction and other cultural material within the confines of the new channel, a proton precession magnetometer survey was carried out by the Wilmington District in December 1983. Archaeologists from Tidewater Atlantic Research carried out an investigation that...

The purpose of this study was to expand the existing biological, physical and chemical data for the Middle Neebish Channel in the St. Marys River to help determine environmental effects of suspension and re-distribution of sediments resulting from proposed winter navigation-related activities (i.e., dredging, icebreaking, ship movements). Field data gathered in 1980 supplements data taken in 1979. It considered the biological importance of shallow, littoral areas and the understanding of...

The entrance of the Matagorda Ship Channel, connects the Gulf of Mexico to Matagorda Bay, Texas. In the landcut, the channel narrows from 2,000 ft to 950 ft (referred to as the bottleneck), greatly focusing the flow and increasing the current velocity in this area and on the Matagorda Bay side causing difficulties in navigation. A successful solution would be removal of the bottleneck to decrease current magnitudes while not compromising operation and maintenance of the Gulf Intracoastal...

The shorelines near the Port of Indiana and Waukegan Harbor in southern Lake Michigan were analyzed using historical aerial photography, direct beach and nearshore placement records, and the U.S. Geological Survey Digital Shoreline Analysis System. The shoreline analysis was compared to the results of the U.S. Army Corps of Engineers Sediment Mobility Tool. High water levels and significant storms led to erosive conditions in the 1980s. During the 1990s and 2000s, nearshore placement of locally...

The objective of this study has been to ascertain the effects of dredging and disposal operations on the water quality of San Francisco Bay with particular emphasis on the degree and duration of associated sediment resuspension. To achieve this objective water quality monitoring was performed in several areas of the Bay influenced by dredging and disposal operations during 1972-1975. The purpose was to record and quantify deviations from background of suspended solids loading, light...

Twelve Navy harbors in the Continental U.S. require maintenance dredging in excess of 0.1 M cu yd per year. They account for 78% of the Navy's annual 9M cu yd total. Two thirds of the area dredged is located within quiet water berths, typically formed between rows of pile piers. About 87% of the material dredged is mud (silty clay or clayey silt) deposited by estuarine processes. (Author)

A hybrid modeling approach using a fixed-bed physical model, numerical models, and analytical techniques was used to study investigation channel shoaling at the mouth of the Columbia River. Sixteen plans for reducing channel maintenance dredging at the existing 48-ft depth and at 55- and 60-ft depths were tested. Effects of the plans on tides and currents were found to be subtle. Nondeepening plans had minor effects on salinity intrusion while channel deepening increased salinities by 1 to 6...

Effects of entrainment by hydraulic dredging operations on aquatic organisms have been and continue to be an issue of environmental concern. Clearly, assessment of actual impacts due to entrainment pose severe technical challenges. Studies to date illustrate the difficulties in determining precise estimates of absolute entrainment rates and have seldom been able to determine population-level consequences with any degree of confidence. Placing mortalities due to entrainment by dredges into a...

In order to provide information on channel location and configuration and assist in planning of dredging operation, the geometry of Fire Island Inlet, New York, is analyzed. Using the 18 sets of aerial photographs taken between April 1962 and April 1972, the locations of shoals, beaches, and channels were determined, digitized for computer analysis, and displayed on drum plots. One of two channel locations proposed by the New York District is considered more appropriate in terms of matching the...

The Mississippi River Gulf Outlet (MRGO) provides year-round navigation between the Mississippi River and the Gulf of Mexico. Dredging, which is periodically required to maintain navigation, may impact Gulf sturgeon. Consequently, Gulf sturgeon use of the MRGO and nearby disposal areas was monitored monthly from 2004 through 2006 using telemetry tracking. A total of 50, 40, and 20 Gulf sturgeon were captured yearly by netting in the Pearl and Bogue Chitto Rivers and fitted with transmitters....

Improvements to coastal-estuarine channels such as deepening and widening increase channel reliability, allow transit of larger vessels at greater speeds, and improve the local and regional economy. However, these benefits are often accompanied by an increase in the rate of channel shoaling, the need to find dredged material placement sites, and environmental concerns. Methods available to estimate the change in magnitude and location of channel shoaling are limited in accuracy because of a...

Interviews with personnel of several Corps of Engineers (CE) Districts and visits to dredged material containment areas showed that little is being done to dewater fine-grained dredged material confined on land.
