California Narrowly Averts Disaster at Oroville Dam [2017-02-28 06:43:33]  recommend  recommend this post  (53 visits) info
Earlier in February severe rain caused the Oroville Dam in Sacramento to reach capacity. The dam is an earth fill dam approximately 770 feet high, making it one of the tallest dams of this type in the Country. On February 11, water began flowing over the emergency spillway, which prior to that point had never been used, and caused erosion at the base of the weir, threatening to undermine the wall at the top of the spillway and potentially cause a catastrophic failure of the dam. Local police [...]

Paper on Underwater Noise Reduction of Marine Pile Driving [2017-01-06 01:19:18]  recommend  recommend this post  (6 visits) info
Impact pile driving of steel piles in aquatic environments produces extremely high underwater sound levels. To address this problem, a double-walled pile has been developed to decrease the total noise transmitted into the water and substrate. The double-walled pile consists of two concentric steel pipe piles flexibly connected by a special driving shoe, allowing for an air gap between the two tubes. The double-walled pile is driven into the sediment by using traditional equipment that strikes [...]
