Why will the Southern Gold Coast beaches look more like they did in the 1960s?
• Extension of the Tweed River entrance training walls in the 1960s intercepted the natural northerly drift of sand along the NSW coast causing it to build up to the south of the training walls. This severely reduced the flow of sand to the Southern Gold Coast beaches. The Sand Bypassing System re-instates the natural drift of sand along the coast by trapping it and pumping it to Pt Danger. • As the Southern Gold Coast beaches will now recieve the natural quantities of sand, these beaches will change and begin to look similar to the way they were before the training walls were extended in the 1960s. This is the reason the Project refers to the pre-1960s as the expected conditions of the beaches in future. • Once beaches do reach a ‘more 1960s’ condition, they will still experience natural variations in sand supply, as all beaches do. One special feature of the Southern Gold Coast beaches is that they are subject to ‘pulsing’ in their sand supply because sand builds up south of Snapper
