ABSTRACT
In 1960, a major dam for water supply to the City of Sydney in Australia was completed in the Warragamba River Valley. This is examined as a case study. Geographical features, the history of the area, including early proposals of use of the river are examined.
The question of submergence of the valley, social consequences, tree removal in the valley, anthropological aspects, recreational use of the area around the dam crest, protection of water quality, catchment management are important parts of environmental implications of the dam.
All these aspects have wide general application, they are of concern, must be carefully analysed and given consideration in concepts of hydraulic structures.
