Report Vindicates Campaign Against Dredging

A report by independent experts has vindicated the campaign to rid the Reef of the impacts of dumping dredge spoil in the World Heritage waters of the Great Barrier Reef.

The report ‘Synthesis of current knowledge of the biophysical impacts of dredging and disposal on the Great Barrier Reef’ was written by experts brought together by the Great Barrier Reef Marine Park Authority and the Australian Institute of Marine Science.

WWF-Australia National Manager Marine Conservation Richard Leck said while the experts did not always agree on impacts the report contained important conclusions, including:

– Any contribution from dredging to large-scale, chronic increases in suspended sediments could affect coral reefs, seagrass habitats, some other seafloor biodiversity, pelagic (open water) and estuarine habitats, fish populations and wildlife.

– … suspended sediments may have serious impacts on recovery of reefs from other disturbances (reducing resilience); such impacts would not be detected in most environmental impact assessments and are potentially important given the degraded condition of many inshore reefs in the regions where dredging takes place.

The experts are saying that sediments from dredging could seriously deplete the resilience of coral – its ability to cope with the normal stresses in its habitat,” Mr Leck said. “This could be slowly killing coral but the way most environmental impact assessments are designed this would not be picked up at all.”

The experts also call for more extensive, long-term and better integrated monitoring and assessment of dredging and dredge disposal in the World Heritage Area.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
