The U.S. Army Engineer Research and Development Center (ERDC) is making progress modeling new auxiliary locks to be constructed at the Montgomery, Emsworth and Dashields sites. "We started on Montgomery with the full expectation that we're going to be doing the same kind of studies for Emsworth and Dashields," said Allen Ham-mack, research mechanical engineer for ERDC's Coastal and Hydraulics Laboratory (CHL). "We began model design in October 2020 and started our initial testing in May 2021. We completed that late last year and began testing the current design in March. We should be done with that soon, and then we will move on to the other two locks." ERDC is partnering with the Pittsburgh Engineer District for a study focused on replacing the locks. Recause the existing auxiliary locks are much smaller than the main locks, the research team is using both numerical and physical modeling to determine the best designs for larger replacements. |
