    Before major lock maintenance and repairs can take place, the lock must be dewatered so that inspections and repair work can be done in relatively dry conditions. Using a barge-mounted crane, the crane operator and rigging crew set a needle dam girder (I-beam) in place in notches built into the lock chamber wall. Then, they place large metal panels known as “needles” against the I-Beam to form a wall called a “needle dam.” (USACE Jacksonville District photo from a 2012 maintenance repair project at the St. Lucie Lock in 2012)

  • 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.
