  • Maintenance dredging of Marina del Rey harbor underway

    Maintenance dredging of the Marina del Rey Harbor entrance channel is underway and is scheduled to be complete in May.

  • Shallow water strategic placement pilot project kicks off in San Francisco Bay

    A steady stream of scows began arriving the morning of Dec. 6 just off the coast of Eden Landing, a 6,400-acre ecological reserve located along the eastern shore of San Francisco Bay, depositing nutrient-rich dredge material in the shallow Bay waters about one mile from its tidal marshes. The daily operation, which wrapped up Dec. 31, is part of a $3.6 million shallow water strategic placement pilot project spearheaded by the U.S. Army Corps of Engineers San Francisco District, California State Coastal Conservancy (non-federal project proponent), and monitored by the U.S. Geological Survey. Sediment has a very important role to play in preparing the Bay Area for sea level rise, storm surge and other impacts of climate change. Beneficially using dredged sediment to help the bay's wetlands accrete is an effective and cost-efficient way to maintain these habitats that sustain wildlife and provide critical flood defenses.

  • Largest Annual Great Lakes Dredging Operation Completed in Toledo

    The U.S. Army Corps of Engineers (USACE), Buffalo District has completed annual dredging of Toledo Harbor and the Maumee River. Dredging of Toledo Harbor is the largest dredging operation on the Great Lakes, ensuring accessible depths for large vessels, the continued flow of commodities across the lakes, and the economic viability of United States waterways.

  • Ranking Ports by Vessel Demand for Depth

    Abstract: The US Army Corps of Engineers (USACE) traditionally uses two metrics to evaluate the maintenance of coastal navigation projects: tonnage at the associated port (representing relative importance) and the controlling depth in the channel (representing operating condition). These are incorporated into a risk-based decision framework directing funds where channel conditions have deteriorated and the disrupted tonnage potential is the highest. However, these metrics fail to capture shipper demand for the maintained depth service provided by the USACE through dredging. Using automatic identification system (AIS) data, the USACE is pioneering new metrics describing vessel demand for the channel depth, represented by vessel encroachment volume (VEV). VEV describes the volume of the hull intruding into a specified clearance margin above the bed and captures how much vessels use the deepest portions of USACE-dredged channels. This study compares the VEV among 13 ports over 4 years by combining AIS, tidal elevations, channel surveys, and sailing draft. The ports are ranked based on the services demanded by their user base to inform the decision framework driving dredge funding allocations. Integrating demand for-depth metrics into the Harbor Maintenance Fee assessment and/or Trust Fund disbursements could alleviate the constitutionality concerns and several criticisms levied against Harbor Maintenance funding.

  • U.S. Army Corps of Engineers Awards Contract to Dredge Erie Harbor

    The U.S. Army Corps of Engineers (USACE), Buffalo District awarded a $682,000 contract to Michigan-based Ryba Marine Construction Co. on Dec. 6 to conduct dredging of the federal navigation channel in Erie Harbor. Dredging of harbors like Erie’s ensures accessible depths for large vessels, the continued flow of commodities across the Great Lakes, and the economic viability of United States waterways.
