Team Van Oord Deploys ‘Silt Wattles’

Working in partnership with Frog Environmental, Team Van Oord has successfully deployed ‘silt wattles’ to help control sediment on a flood alleviation scheme in West Sussex.

“The innovative solution has been used at the Clay’s Lake Flood Prevention Scheme which Team Van Oord is delivering on behalf of the Environment Agency,” TVO said in its release.

The Clay’s Lake scheme comprises the removal of an existing dam which is being replaced with a larger dam. This will increase the lake’s capacity from 10,000 cubic meters to nearly 400,000 cubic metres, thereby reducing the risk of flooding to more than 280 homes in the area, and to Gatwick Airport.

Natural silt wattles are used as check dams in rivers, ditches, swales and gullies to reduce the speed of water and aid natural sediment deposition. The natural media supports silt trapping and can also be used in conjunction with a floc mat to enhance sediment capture and reduce downstream turbidity.

The design of silt wattles, which are manufactured in the UK by Frog Environmental, ensures they are malleable and will fit to the contour of uneven surfaces, where they can be staked in place or tied off.

Other innovative techniques to reduce silt pollution are being trialed at Clays Lake, these include Water Lynx blocks to aid water settlement and flocculation mats to trap silt in water before entering the watercourse.

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.
