  • Houston Ship Channel Expansion Channel Improvement Project (ECIP) Numerical Modeling Report: Increased Channel Width Analysis

    Abstract: The Houston Ship Channel is one of the busiest deep-draft navigation channels in the United States and must be able to accommodate larger vessel dimensions over time. The U.S. Army Engineer District, Galveston (SWG) requested the U.S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory perform hydrodynamic and sediment modeling of proposed modifications along the Houston Ship Channel. The modeling results are necessary to provide data for salinity and sediment transport analysis as well as ship simulation studies. SWG provided a project alternative that includes channel widening, deepening, and bend easing. After initial analysis, two additional channel widths in the bay portion of the Houston Ship Channel were requested for testing. The results of these additional channel widths are presented in this report. The model shows that the salinity does not vary significantly due to the channel modifications being considered for this project. Changes in salinity are 2 parts per thousand or less. The tidal prism increases by less than 2% when the project is included, and the tidal amplitudes increase by no more than 0.01 meter. The residual velocity vectors do vary in and around areas where project modifications are made.

  • USACE lifts small craft advisory for Arkansas River

    The U.S. Army Corps of Engineers lifts the small craft advisory for the Arkansas River. Small-craft advisories are issued when flows reach 70,000 cubic feet per second. While flows have receded, USACE officials urge boaters to always use caution when on the river.

  • Corps to begin dredging Newport Bay Harbor, completing east jetty repairs

    The U.S. Army Corps of Engineers Los Angeles District will begin dredging the Newport Bay Harbor entrance channel and perform repairs on the harbor’s east jetty in mid-April at Newport Beach, California. A $3-million contract to perform the work was awarded Feb. 24 to Pacific Dredge and Construction LLC, located in San Diego. The City of Newport Beach is the non-federal sponsor of the project.

  • 2021 runoff forecast remains below average; Virtual spring public meetings April 6

    Reservoir inflows in the Missouri River basin above Sioux City, Iowa (upper Basin) were well-below average in March. The updated 2021 upper Basin runoff forecast is 21.3 million acre-feet (MAF), 83% of average.

  • A Winter to Remember: Corps of Engineers continues annual winter maintenance fight to preserve aging infrastructure

    The American Society of Civil Engineers 2021 infrastructure report card released in March was less than perfect for the nation’s inland navigation system. According to the report, they gave the Inland waterway infrastructure a D+. The ASCE report said the infrastructure "includes locks and dams as well as navigation channels” but added that shipping delays cost up to $739 per hour for an average tow within the United States.
