USACE VIDEO: Jekyll Creek Thin Layer Placement Pilot Project

The U.S. Army Corps of Engineers, Savannah District, with expertise and resources from Cottrell Contracting of Chesapeake, Va., recently completed the first portion of a dredging pilot project in the Jekyll Creek/St. Simons Sound area.

The pilot project seeks to find environmentally viable, cost-effective and beneficial uses for “pluff mud,” a silty, watery type of dredge material that is difficult to work with and expensive to dispose of.

The dredging project deepened a channel near Jekyll Creek to 10 feet, placing 5,000 cubic yards into a nearby marsh and the other 220,000 cubic yards into a naturally scouring “deep hole” in St. Simons Sound.

The deep hole is approximately 60-70 feet deep compared to the surrounding depths which average 30-40 feet.

For the marsh portion, coconut coir logs were used to retain the dredged material in a 5-acre plot and allow marsh grasses to adapt to the new level, which was anywhere from two inches to a foot higher in elevation.

USACE said that scientists and researchers with Georgia Southern University and the University of South Carolina will monitor the marsh and associated wildlife to establish the health of the marsh and the associated ecosystem.

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.
