River Freshney Dredging Set for Late Autumn

Plans to dredge a section of the River Freshney have been announced by the Environment Agency after research revealed new information about the amount of silt in the channel.

The dredging will help reduce flood risk and will be carried out on the stretch of river between Cromwell Road and New Haven Terrace, including a 200m section between the railway culverts.

Previously EA officers have explained that no silt has built up in the channel in the last 40 years, meaning there was no need to dredge.

However, after looking back even further into the history of the river, they found that some silt had built up between the time the river was last improved in the 1950s and the introduction of modern maintenance techniques in the 1970s.

Adrian Clack, Asset Performance Team Leader said: “We carry out regular reviews to make sure we’re taking the best approach to maintenance, based on all the available evidence. Dredging where silt has built up will restore the profile of the river and help water flow freely, reducing flood risk.

We’ll also continue our regular maintenance program and will continue working with our professional partners, who are looking at other ways of improving the river’s condition.
In areas ear-marked for dredging, up to 600mm (2 feet) of silt accumulated before the 1970s. Other parts of the river have seen only about 100mm of silt build-up – approximately the height of a street kerb – and will be cleared by weed-raking,” added Clack.

Weed-raking is a part of normal maintenance that was introduced in the 1970s and prevents further silt from building up in the river.

Other parts of the river have not seen silt accumulate and therefore do not need additional maintenance above the routine weed-raking the Agency already carries out.

Dredging work is expected to start in late autumn and finish in the new year so as not to disturb protected nesting birds and other wildlife.

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.
