Here is some information I found on an information sign at the Spit.

The Nerang River Entrance has a notorious history of instability. The ever-changing river mouth was moving northward at rates of up to 60m per year, eroding South Stradbroke Island and choking the Broadwater with sand. These hazardous condtions resulted in several boating tragedies and represented a major impediment to recreational and commercial baoting on the Gold Coast.

The construction of the Gold Coast Seaway just south of the then existing river mouth has eliminated the problems associated with the old bar and has provided a safe access to the ocean. Two training walls, 320 metres apart, have been constructed. The south wall extending 600 metres ofshore and the north wall 400 metres. The walls are oriented slightly north of east to reduce wave penetration into the broadwater. Dredging works have been carried out to excavate new navigation channels, with fill being used to close the old bar and create Wavebreak Island. This island captures storm waves and protects the low lying western foreshore of the Broadwater from erosion.

Concrete cubes of 20 and 25 tonnes size form the core of the training walls. All 4,500 of these were cast on site. Aprons of rockvarying in size from 2 - 15 tonnes -- 1 million tonnes in all -- were placed around the core. Construction of the training walls is such that in the event of erosion, the outer edges of the apron relocate into the eroded seabed to prevent undermining of the walls.

This is just a direct copy. If anyone could help me reword these paragraphs I think they'd be great for this article and helpful for my assignment. — Preceding unsigned comment added by AQjosh (talk • contribs) 06:50, 21 May 2006 (UTC)[reply]
