Disappearing West Beach sand could be replaced with coarser import, expert says
Replenishing West Beach with coarser sand quarried from onshore will help stop it drifting north, an expert says, as the SA Government prepares to return 100,000 cubic metres to overcome erosion and sand drift. This included what DHI called "mass nourishment", where 1.8 million cubic metres of sand would be carted to West Beach, Henley Beach South and north of the Torrens Outlet. A smaller, "interim management" option is to extend the West Beach rock wall, cart in 100,000m3 of sand to the Torrens Outlet and Henley Beach South, and supply 30,000m3 each summer to create a "seasonal beach in front of West Beach Parks". "To begin to address the report's findings and help West Beach, the immediate priority is to cart sand to replenish the eroding West Beach," he said. "The report makes it clear that even if recent management activities were to be maintained, dune erosion would continue around West Beach and Henley Beach South and progressively move north.
