National Port Issuesby John B. Herbich, Texas A&M Univ, College Station, TX, USA,
Abstract: 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 of U. S. economy, vis a vis the world economy, changes in the shipping fleets, lack of federally-funded deepening of navigational ship channels and ports during the last decade, and changes in the world economy have all affected the transportation system needs. Findings of the Committee are presented. Some of the findings call for construction of multipurpose port capacity to handle bulk vessels requiring at least 50 ft or 55 ft of water depth on each of the coasts. Selection should be made on the basis of cost of construction; adequate inland transportation systems; maintenance dredging; and environmental consequences of dredging.
