ENVIRONMENTAL EFFECTS OF ESTUARY BARRAGES

The term barrage is applied in this paper to a dam in a river estuary which has a substantial depth of water on both sides. Barrages are constructed to assist navigation, flood control, energy generation or land transportation. The primary purpose of most barrages is to reduce the tide range over the enclosed part of an estuary. Active consideration of the environmental effects of projects when at the design stage is now widely practised. The paper focuses initially on how the tide range would be altered by each type of barrage and the consequences thereof for currents, waves, sediments and water quality parameters. Ecological issues are then introduced, followed by land drainage, flooding, debris and landscape considerations.
