At the same time, the escalating costs of waterway projects and shift of major funding responsibilities to local sponsors brought attention to a design process that compensates for uncertainty with conservative rules of thumb (Bertsche and Cook, 1980; National Research Council ARCS, 1983~.

Water Resources Policy Although funding development of port facilities is the responsibility of civil authorities and private enterprise, the federal government has historically led development of the port and waterway system (Heine, 1980; Na tional Research Council, 1983, 1985~. The major costs of construction,

DOCK The water space between adjacent piers or wharves in which vessels are berthed; an artificial basin or enclosure fitted with lock gates to retain a level of water undisturbed by entering or departing vessels (wet dock) ; any dock in or on which a vessel can be made to lie completely out of the water (dry dock)

. Until the 1970s, the federal government was the major source of funds for basic channel and waterway infrastructure, leaving actual port facility and land-side access up to local ports, other agencies, and private enterprise (especially for petroleum terminals)

One such technology, shiphandling simulation, has been used for operational Gaining (for example, emergency procedures and maneuvering) , analyzing marine casualties, evaluating vessel designs for maneuverability, evaluating bridge equipment, evaluating aids to navigation, and assessing the suitability of a particular vessel for a new port or transit situation Shiphandling simulation techniques have also been used to select waterway configurations, usually as modifications to segments of an existing system, that accommodate economic, safety, and environmental interests.

In recent years, computer-based simulation has benefitted greatly from the advance of computer technology to help determine the swept paths of ships and integrated tows (oceangoing and shallow draft) under a variety of waterway configurations and operating conditions.
