SubSeaSail G6 Platform Passes the Test

The Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers (USACE) along with logistical support from the US Navy successfully tested their SubSeaSail G6 platform at multiple coastal sites off the Vieques Island, Puerto Rico. Remote sensing applications for monitoring underwater unexploded ordnance were demonstrated by mounting a passive filter assembly to the G6 platform to detect explosive compounds in the water. Additionally, a water quality sensor was mounted to monitor other water quality parameters including temperature, salinity, depth, and turbidity.  During

storm surge barriers, such as the Delta Works and River Thames barriers.  In the US the New Bedford/Fairhaven port was severely flooded by hurricanes in 1938 and 1954 causing $8.3 million in damages, which lead to the construction of the New Bedford Hurricane Barrier in 1962 by the Army Corps of Engineers at a cost of $18.6 million.  The Army Corps project summary notes that this barrier has since prevented $24.1 million in flood damages (to 2011), and properties within the protected area are no longer required to purchase FEMA flood insurance.  The Port of New Bedford does emphasize

Mat Sinking Unit in Modernization Drive

Millions of dollars of goods are transported up and down the Mississippi every year. This transportation is made possible, in part, by the U.S. Army Corps of Engineers (USACE) Mat Sinking Unit and its crew, who work tirelessly each season to protect the riverbanks with concrete mats and prevent erosion.The Mat Sinking Unit was built in 1940, widened in 1960 and is being replaced over the next several years with new and improved plant. The new design will double the number of mat squares that can be placed in a season.USACE Vicksburg District (MVK), USACE Marine Design Center (MDC), SIA Solutions LLC

WAM-V 8 Unveiled

;The inherent stability of the WAM-V makes it the perfect platform for time-sensitive and mission-critical surveys and inspections. This 8’ model positions the WAM-V into a new tier of ease of use and transportability. Our team is proud to leverage our robotics expertise to support the U.S. Army Corps of Engineers in their vitally important mission.”The 8’ WAM-V will feature dual jet-drive propulsion to enable operation in as little as 6” of water, and a configurable form factor that allows it to reduce its footprint to fit in tight spots, such as between the pilings beneath a pier

New Site Hosts Corps’ Hydrographic Survey Training

What do hydrographic surveys ― the scientific measurement and description of physical features at the bottom of bodies of water ― have to do with the U.S. Army Corps of Engineers and marine construction? In a word, plenty.Francis Postiglione, chief of the New York District's Survey Section, Operation's Division, said, "Surveying is at the root of all projects in coastal and inland waterways," adding, "Surveying also plays a large role during the bidding process and awarding of contracts, especially with estimating costs."Importance of SurveysHydrographic surveys are important

The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the U.S. Navy in Memphis since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air- or water-borne transportation systems. (Photo: U.S. Navy)
