The book identifies several problems in dredging ports, including the long interval between a decision to deepen a port and the time the alterations are complete. The United States needs to speed port construction to meet changing needs, and the committee recommends that we prepare for future needs by dredging now. A National Dredging Needs Study (NDNS) was initiated by the Institute of Water Resources (IWR) of the USACE to investigate the adequacy of U.S. navigation channels and harbors to accommodate changes in the world merchant fleet well into the 21st : Jennifer K.

Purpose: To study and disseminate information on the planning, design, construction, maintenance, operation, pollution control, and technical functioning of ports and harbors, including coordination with port and harbor agencies on the engineering aspects of: (1) meeting the needs of the locality and those of waterborne transportation, commercial (including fishing), and recreational interests.

Over harbors on the Atlantic coast have been stabilized, usually with rubble mound structures. These works deflect wave energy and block longshore sediment transport, thereby maintaining navigable conditions in harbors, ports, and channels. Dredging is another important activity at Atlantic harbors and ports. The official journal of the International Association of Ports and Harbors (IAPH), Ports and Harbor Magazine provides actionable insight into port-related developments from security to software. The magazine has been published since the IAPH's inception in November   Dredging shipping channels and ports takes time and money.

Periodic maintenance dredging is required for safe navigation for recreational vessels within Huntington Harbour, Seal Beach and Huntington Beach, California, resulting in dredge material that must be moved elsewhere, creating both challenges and opportunities. ORIGINS OF THE STUDY Acting on its charter "to consider questions of the relation of engineering and technology to navigation and the commerce of the sea and waterways," the Marine Board agreed in December to a request of the U.S. Army Corps of Engineers to appraise the nation's needs for dredging in the coastal ports for the near- and mid. With their increased size, ships need improved navigation channels to enter and leave ports efficiently, quickly, and safely. Few rivers or harbors are naturally deep. Underwater excavation is called dredging. After the initial excavation needed to establish a channel, dredging must be done periodically to keep it clear and safe for navigation.
