Summarising the TRESB Project

1) The problem with the Tweed River is that sand and silt continuously built up on the southern side of the River. The buildup was caused by the four nearby outlets which under went the process of longshore drift which moved all sand to the Southern Side of the River. This caused problems for cargo ships trying to enter as it was very unsafe because of sand bars forming over the mouth of the River. The government tried to extend the breakwaters three times in 1962, 1969 and 1994 but after a short time period, this failed and a new solution had to be constructed.
2) The solution to this problem was eventually to create massive pipes that would dump the sand to four various Outlets nearby. This only happened recently after the extension of breakwaters failed and sand built up at the entrance again therefore recreating a artificial longshore drift process. Also, it replace trucks taking sand up to the Gold Coast for beach nourishment as this process was expensive and time consuming.

3) The TRESB Project was a great success as it solved the problem of sand buildup at the TRE which allowed the safe entrance for cargo ships. The areas affected were the Tweed River, the residents living close to the Tweed River, the East and West Snapper, Kirra and Duranbah Outlets and the Gold Coast as they were now undergoing a process of beach nourishment which made them better for tourists and swimmers/surfers. This is also named as a success as it is classified as one of Australia's most successful coastal management development completed.
