  • San Francisco District planning team applies nature-based solutions to Roi-Namur recovery efforts

    U.S. Army Corps of Engineers San Francisco District’s knowledge of and push for Engineering with Nature principles and designs reached a new high as the district’s EWN expertise jumped an ocean all the way to Roi-Namur, the second largest island of the Kwajalein Atoll in the western central Pacific Ocean. It’s part of the Republic of the Marshall Islands, and it lies 2,100 nautical miles southwest of Honolulu and about 4,200 nautical miles southwest of San Francisco. On Oct. 11, a San Francisco District project development team submitted its preliminary EWN and non-EWN design plans to protect facilities against large waves to the USACE Honolulu District to present to the U.S. Army Garrison – Kwajalein Atoll and U.S. Army Space and Missile Defense Command.

  • Influence of Fines Content on the Progression of Backward Erosion Piping

    Abstract: Backward erosion piping is a form of internal erosion that endangers the structural stability of levees and dams. Understanding the factors that influence this form of erosion can result in improved risk assessment and more appropriate modifications to new and existing structures. Historically, it has been assumed that the presence of silt size particles would reduce the gradient required for erosion. This study investigated the influence of fines content on backward erosion piping through a series of laboratory experiments on silty sands. Laboratory results show that as the fines content increased in the samples, so too did the gradient required to produce and progress piping to failure. The results indicate that a new factor is needed to properly account for silt content in backward erosion piping (BEP) risk assessment of silty sands.
