TRESB project

The TRESBP(Tweed River entrance sand bypassing project) was a coastal management strategy put into place in Tweed Heads NSW.

The problem that made this management strategy occured during the 1950s when the entrance of the Tweed River became a hazard to shipping because of the frequent sandbars that were forming across the entrance of the river mouth.

The initial solution to the problem was to construct breakwaters that would stop the buildup of sand the entrance of the river mouth and although it was at first sucessful this solution itself caused problems due to the new buildup of sand around the breakwaters which interfered with the natural process of longshore drift and the supply of sand to beaches on the north of the Tweed River.

The solution to this new problem of sand buildup was to build a mechanism that would pump the sand around the breakwaters to the surronding beaches of the local area and also to dredge some of the sand north to the gold coast where the beaches were scarce of sand.
