7.6 The Tweed River Entrance Sand Bypassing Project

1. It became necessary to extend the Tweed River breakwaters because of the continual sand build up.
2. It would have meant they didn't periodically transport sand down to the Gold Coast beaches to replenish their sand supply, as they didn't have their natural supply of sand.
3. The river became unsafe as it would need continual maintenance which would jeopardise the safety of the river entrance for boats.
4.it was a short term solution because it was continually eroding the sand, and was costing a lot of money to continually transport the sand to the Gold Coast beaches.
5. The project aimed to replicate the process of longshore drift. Sand is pumped from where it sits on the southern side of the Tweed River, pumped through pipes across the Tweed River to one of four outlets where sand is released onto the beach.
6. I think it is a clever organisation, which has effectively used the natural processes of longshore drift to maximise the effectiveness of their organisations aims.
7. In book
8. You can see the continual erosion that has occurred between the 12th of October, 1962 and the 19th of December, 1994.
9.  I think it is approximately 85 metres long.
