Summarising the TRESB Project

1. The problem which lead to the TRESB Project.

The problem was that the entrance to the Tweed River at the southern end of the Gold Coast. The entrance was becoming a hazard to shipping because of the sandbars that were forming across the river mouth. These sandbars were becoming dangerous to shipping as it would potentially contact the the ship and cause great damage. The breakwater that had been built was still not doing its job and longshore drift was still pushing sand into the entrance of the river.

2. The solution to the problem.

The solution to the problem was to build the Tweed River Entrance Sand Bypassing Project that involved building pipes that would run across the river and would go to the other beaches. These pipes would pump the sand from the river entrance where it accumulates. Via a system of pipes the sand would travel to one of four outlets where it would be decided where the sand would be deposited.

3. The result of the project. What areas were effected and how? Do you think that it was a success?


I think that the whole project was a success apart from the fact that the natural process of lonshore drift was totally destroyed. Even though machines are used to replace the need for lonshore drift we have still lost a vital part of the system at the beaches. Apart from this the whole project was a great success as it increased the safety of the ships that enter the river and it is working well. This project replaces the sand lost by using the machines and it is a very expensive process but it is needed.
