Abstract:
The article analyzes the development and modernization of energy and technological equipment, as well as soil productivity of dredging projects of both foreign and domestic manufacturers of dredging equipment. The emphasis has been placed on the installation and use of submersible pumps. The productivity of soil dredges has been found to increase due to changes in the design of soil sampling devices and soil pumps. The main characteristics of the American river dredgers with hydraulic cultivators and domestic river diesel dredgers with hydraulic soil cultivators have been considered and evalua

Abstract The white clam Spisula solida is harvested along the entire coast of Portugal using mechanical dredges. In this study, the total direct mortality of the macrobenthic community caused by three types of clam dredges (north dredge—ND, traditional dredge—TD, and the metallic grid dredge—GD) used in the S. solida fishery was determined and compared. The relationship between mortality and catching efficiency for each type of dredge was also assessed. Our results showed significant differences for total direct mortality between the ND and both the GD and TD dredges. This difference was large

Abstract:
ABSTRACT Trailing suction hopper dredges maintain ports and their entrance channels around the world. Several of these dredges have already operated as oil spill cleanup vessels as a secondary assignment. Different types of available oil spill response systems were applied. Recent developments allow these dredges to use their own dredge pumps, making these vessels by far the largest capacity oil spill cleanup vessels available in the world. The add-on system requires no modifications of the vessel and a relatively low investment. Tests have documented very good performance.

Diamond and gold mining has been practiced by artisanal miners in the Central African Republic (CAR) for decades.

Abstract:
Impacts of scallop dredges and their efficiency were examined experimentally in three areas with different soft substrates in Port Phillip Bay, southeastern Australia. Physical and biological changes were measured on large (600 × 600 m) experimental plots that were dredged with an intensity and duration similar to normal fishing operations. Dredges were most efficient on soft, flat, muddy sediments (51-56% of commercial-sized scallops caught) and least efficient on firm, sandy sediments with more topographic variation (38-44%). Dredging flattened all plots, but changes to topography were most

Global scallop fisheries are economically important but are associated with environmental impacts to seabed communities resulting from the direct physical contact of the fishing gear with the seabed.

AbstractA number of dredging projects have unknowingly and unfortunately encountered munitions and explosives of concern (MEC). MEC have been discovered on dredges (e.g., in dragheads, cutterheads, pump casings) and at the dredged material placement site. Detonations have occurred that have either damaged the dredge plant or have even sunk the dredging vessel. A number of recent dredging projects have proactively addressed MEC issues before the start of construction, thereby greatly reducing overall risk and MEC cleanup costs.

Both the dredging operations and the management of dredged materials may have heavy impacts on coastal and marine ecosystems. Dredged materials, in particular, have been considered for a very long time nothing more than a waste meant for disposal. Now the time has come to move from the ‘disposal approach’ to the ‘waste recovery’ or, even better, to the ‘waste can be a non-waste’ ones. Unfortunately, the management of dredged materials is committed to a congeries of rules, which build up a framework of law that appears plainly fragmentary and incoherent. The road is still long (and winding).

Abstract:
Navigation channels, turning basins, and other US Army Corps of Engineers (USACE)–managed navigation infrastructure often serve as repositories for contaminated sediment from off-site sources. As much as 10% of the material that USACE dredges on an annual basis is contaminated such that it requires additional and more costly management (for example, rehandling and placement in managed confined disposal facilities). Presence of contaminated sediments constrain potential management options resulting in additional costs and opportunity loss from the inability to beneficially use the material. One

Abstract:
To maintain the navigability of the Calcasieu Ship Channel (CSC), the US Army Corps of Engineers annually dredges millions of cubic yards of sediment from the inland channel. To assess sources of channel shoaling, a previous study examined river and bankline erosion as inputs. Results from that study accounted for approximately 20% of dredged volumes. Through the support of the Regional Sediment Management Program, a follow-up investigation reviewed prior sediment budgets, identified potential missing sediment sources, modeled potential sediment pathways, and utilized geochemical fingerprintin

Abstract:
This US Army Corps of Engineers, Regional Sediment Management, technical note describes a geodatabase of federal coastal and inland navigation projects developed to determine the extent to which RSM goals have been implemented across the USACE at the project and district levels. The effort 1) quantified the volume of sediment dredged from federal navigation channels by both contract and USACE-owned dredges and 2) identified the placement type and whether sediment was placed beneficially. The majority of the dredging data used to populate the geodatabase were based on the USACE Dredging Informa

Abstract:
This technical note is the third in a series about using native plant communities to enhance dredge material placement areas (DMPAs), confined disposal facilities (CDFs), and projects where dredged sediments are used for various engineering purposes. DMPAs and CDFs occur in numerous locations spanning different geographic locations nationwide. Oftentimes, these containment dikes are constructed using earthen materials. The materials are either barged in from an off-site location or obtained on-site from new or virgin materials, consisting of heavy clay particles and sediments removed from the
