CONSTRUCTION AND MODEL INVESTIGATION OF STORMWATER OUTFALL

Abstract

Posford Pavry Sinclair and Knight were commissioned in 1976 to design a new stormwater outfall off one of Sydney's surfing beaches. The location of the outfall was dictated by a previous outfall which had been built in the dry when the beach line was much further seaward but which had been destroyed by wave action when the beach line retreated to the 1976 position (a distance of approximately 50 metres (Figure 1)).
