Importance of Murray Dredging Highlighted

Federal Environment Parliamentary Secretary Senator Simon Birmingham and South Australia Minister for the River Murray Ian Hunter have recently advised that the decision has been made to start dredging the Murray Mouth to remove sand build-up.

It’s vital that the mouth remains open to keep the ecosystems in the Coorong healthy, as well as maintain connectivity between the river, the Coorong and the Southern Ocean to discharge salt and other nutrients out to sea,” Senator Birmingham said.

Had there been no water recovery towards the Basin Plan, the MDBA had determined that it was likely that dredging would have been required in autumn this year.

“It’s a good sign, with the Basin Plan only partially implemented, the need for dredging was deferred. This indicates the additional water being delivered for the environment is helping to improve flows and demonstrates the importance of our commitment to implement the Basin Plan in full and on time.

“However, due to drier conditions across the Basin flows throughout the system have reduced, sand has started to accumulate inside the mouth and dredging is now required.

“The Murray-Darling Basin Ministerial Council agreed last month to allocate $4 million to the dredging in 2014–15 and I thank all jurisdictions for their cooperation to manage this situation,” said Senator Birmingham.

Minister Hunter said keeping the mouth open was important for the health of the whole River Murray system.

Maintaining an open Murray Mouth is a key objective under the Basin Plan and the present situation shows how important it is to continue to maintain good flows through the river system,Minister Hunter said.

Even with full water recovery, the Basin Plan recognizes there will still be times when dredging is needed to maintain adequate connectivity with the sea.

“Dredging has shown to be the most effective method for keeping the mouth open under periods of lower flow over the barrages, in terms of cost and environmental criteria, compared with a range of structural and other methods.”

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.
