Environmental impacts of dredging and other

2012-9-1  Dredging activities potentially affect not only the site itself, but also surrounding areas, through a large number of impact vectors (e.g. turbid plumes, sedimentation, resuspension, release of contaminants, and bathymetric changes) (Wolanski and Gibbs, 1992). Effects can be immediate or develop over a longer time frame and they may be temporary or permanent in nature.

Dredging Impact On The Global Economy DSC Dredge

Deep mining with hydraulic dredges: Recent trends toward deeper mining have prompted the industry to design hydraulic dredge options that compete with clamshell dredges. For instance, based on a customer’s application, DSC Dredge manufactured a sand mining dredge in 2009 that has the capability to dredge to 200 feet (61 m) deep.

Best practice environmental management involves minimising impacts at and near the dredging and disposal sites and has economic, social and environmental benefits for the proponent. Dredging proposals generally fall into one or more of the following three categories: • capital works for new marine infrastructure;

Environmental Remediation Dredge

Environmental remediation dredging removes built-up and contaminated sediments from waterways allowing for the flow of freshwater to bring in nutrients and flush out waste. The environmental improvements available through dredging can positively impact human health as well as the animal and plant populations in a surrounding area.
