UK: Environment Agency Finishes Preston Beach Sea Defences Repairs

The Environment Agency has completed five weeks of intensive work to restore the sea defences damaged by the severe winter storms at Preston Beach.

A significant amount of shingle was washed away by the waves at the Preston Beach Sea Defence Scheme, to the East of Weymouth.

During a series of severe storms in early January and February 2014 the Preston Beach Sea Defence Scheme took a pounding and lost so much of its shingle in front of the promenade that the sea wall was in danger of breaching or being overtopped by large waves.

Completed in 1996 to offer protection to the A353 and some 30 properties at Lodmoor and Overcombe, the scheme has a promenade and sea wall, fronted by imported shingle which acts as a buffer to wave energy.

A number of severe flood warnings were issued in the New Year due to the loss of beach material during previous storms and the ability of waves to run up and over the sea wall, the road has been closed at these times to avoid risk to life from waves laden with shingle hitting vehicles.

The local Environment Agency operations teams were supported by staff from the Midlands Region during January to recover material between the storms which has been lost off the beach. This work has had to be repeated several times up until the extreme storm on 5 February.

The beach was reduced to no crest and foundations in front of the promenade were exposed.

The Agency mobilised a contractor to carry out emergency reinforcement of the beach crest using rocks from Portland placed under the shingle down the beach in front of the promenade to protect the foundations and the integrity of the scheme.

The work involved burying limestone boulders up to six tonnes in weight within the beach over a length of 350m to ensure a permanent crest in front of the sea wall. Around 3,955 tonnes of rock was placed under the shingle to maintain the crest width during future storms,’ said Neil Watson for the Environment Agency.

The Environment Agency held a well-attended local meeting on 26 February to explain the emergency works and future commitments to monitoring and improvements.

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.
