A record amount of sand has been moved in the annual campaign to provide safe navigation at Mandurah Ocean Entrance and to widen Town Beach.
Department of Transport (DoT) General Manager of Coastal Infrastructure Steve Jenkins said that the annual sand bypassing and replenishment project, funded by the State Government and City of Mandurah at a cost of $1.7 million, had recently been completed with the largest amount of material moved in one campaign being recorded.
Approximately 195,000 cubic meters of sand had been excavated from Doddi’s Beach and pumped eastward on to nearby Town Beach during the five month project which is essential to maintain the entrance channel.
“It was originally estimated that bypassing at the Mandurah Ocean Entrance this year would move a larger than usual target volume of 180,000 cubic meters. The final volume was well beyond expectations, but necessary to match the natural sand movement experienced along this section of coast,” Mr Jenkins said.
Mr Jenkins said that a similarly successful campaign earlier this year at Dawesville saw a total volume of 114,000 cubic meters of sediment moved from a sand trap on the southern side of Dawesville Channel to the north to continue the natural movement of sand along the coast.
The Dawesville and Mandurah bypassing projects represent a $2.7 million investment in coastal management ensuring the safe navigation of the Peel Harvey Estuary and the protection of Mandurah’s beaches.
