ABSTRACT:
A system and method for cleansing a polluted harbor by achieving general circulation of water between an open sea and the polluted harbor are disclosed. The system and method utilize the natural wave-like behavior of the water when ocean tides propagate from a harbor entrance in the open sea to a back harbor and back out to sea again. Surface elevation variations along the propagating wave provide hydrostatic pressure differentials between areas along the path of propagation. When connecting two such areas with a conduit, the pressure differential between two areas causes water to flow in the conduit. The system includes a conduit which connects an area of the open sea with a back harbor area. The conduit may be installed along a channel of the harbor so that it extends through the harbor to the back bay, or it may be positioned to cut across or through a strip of land separating the back harbor from the open sea. One end of the conduit has a check valve, thus forcing water flow through the conduit in only one direction, establishing a positive circulation of clean sea water flushing the polluted harbor. The check valve may be automatically responsive to directional water flow in the conduit, differential tidal water pressures between the open sea area and the inner arbor area, or it may be actuated by a suitable external control systems and power sources.
