National Port Issues
The adequacy of U. S. ports to meet the Nation's present and future needs was evaluated by a Committee of the Marine Board, National Research Council. The changing character...
Overdredging at Existing Gravity Structure
Pacific Elevators Ltd. decided to upgrade Berth No. 2 to handle ships up to 70,000 DWT. The difficulty was to maintain the support of the cribs after dredging of the berth to minus 45...
Underwater Compaction of Sand Fill During Placement
A system and related equipment have been developed, and tested on a recent dredged fill project, to compact sand, either clean or with limited silt, in lifts several feet in thickness...
Reservoir Sedimentation and Desilting in Taiwan
The island of Taiwan is infested with numerous flashy streams with steep slopes and huge sediment loads, thus, the major reservoirs have experienced heavy sediment deposit. The encroachment...
Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...
Dredged Spoil Storage Basin in the Coastal Waters Near Rotterdam
The maintenance dredging for the Rotterdam harbour area amounts to 23 million m**3 per year, 10 million m**3 of which is polluted to such an extent that a controlled storage is required....
