Abstract

As the world demand for coal has increased, the number of colliers arriving at Hampton Roads, Virginia, to load coal has exceeded the ability of the port to supply the demand. As a result, a substantial backlog of ships waiting to load coal is presently taxing the anchorage capacity of the harbor. A recent estimate is that 130 ships are waiting about 38 days each for their turn at the loading factl1t1es. In addition to the anchorages tn Hampton Roads and the lower James River, new anchorages have been opened to accomodate these ships, one on the southern side of the Chesapeake Bay entrance, off Lynnhaven and the other to the west of Cape Charles. Each of these ships. in maintaining a crew aboard, produces waste materials of several varities which are mixed with the water surrounding the vessel as it lies at anchor. In order to estimate the impacts which this effluent may have on the various aspects of Chesapeake Bay, it is first necessary to estimate the motion of the effluents subsequent to leaving their ships. This report, based on previous experimental work in the region. is intended to provide such an estimate.
