Summarisung the TRESB Project

1. The problem that led to the TRESBP was that longshore drift moved sand (that was moving North) across the mouth of the Tweed River, this then put boats and ships moving into the river at risk as the offshore sand bar could damage them.
2. There was one unsuccessful solution and then they updated it and now the solution is considered one of the greatest  management strategies introduced. The first was the dredging and transport of the built-up sand Northwards towards the Gold Coast, this was expensive and environmentally unfriendly so there was a need to update and improve the strategy. The new strategy was then to build underground pipelines that pumped the built-up sand Northwards to the beaches that have been deprived of sand.
3. The result of the project was the beaches that were deprived of sand are no longer deprived of sand so yes, the project was a success.
