ABSTRACT:
A barrier device comprising a plurality of gated structures extending between opposite shores of a tidal estuary provides a means of preventing intrusion of heavier, colder sea water with each incoming tide and to then be the means for ejecting large volumes of collected sea water together with mud, sand and sewage pollutants. The eventual effect will be to create a body of fresh water of previously unattainable purity. This purity is renewable with the discharge of any excess water available. During periods of heavy withdrawal from the upstream pool all gates can be locked closed. After danger of flooding has ended the upstream pool can then store a very large volume of fresh water. Flood water is ejected as fast as it flows into the pool. Tidal power can be used to force flood water into the sea.
