| 説明 | U.S. Army Corps of Engineers Buffalo District contractor Ryba Marine Construction Co. pumps out dredged material from a scow in Cleveland Harbor and into a confined disposal facility, Cleveland, OH, November 3, 2020. Subject to the availability of funds, Cleveland Harbor is dredged twice every year, once in the spring and once in the fall. Natural sedimentation within the federal channel from upstream erosion is the main reason for the need for dredging. |
