About 50,000 cubic metres of sand will be trucked from quarries around Adelaide to protect a local beach from ongoing erosion.
Deliveries will start next week and continue until September, bringing the equivalent of 20 Olympic-sized swimming pools of sand to the West Beach foreshore, where wave action constantly pushes sand further north.
Department for Environment spokesman Murray Townsend said adding large volumes of sand to West Beach would significantly improve the local conditions.
"The sand not only benefits West Beach but also other beaches, including Henley Beach South and Henley Beach, as the sand naturally moves north," he said.
Strong winds, large seas and significant rainfall especially in the winter months also contribute to the erosion of Adelaide's beaches.
Officials continue to monitor local conditions to determine where sand is needed but have already planned for another 50,000 cubic metres to be trucked to West Beach next year.
The state government is also conducting a review of beach management to provide a long-term solution to erosion issues.
