Underwater dyke set to save Cửa Đại beach from erosion

“A  一m high underwater dyke wall would pull back a huge amount of sand to build up a large sandbank on the beach. It’s a measure to protect the beach from erosion

“Of course, it’s not only one solution, but various measures (dredging of Cửa Đại estuary, ban on illegal sand mining activities, forest plantation and overview of upstream hydropower plants) should be planned to stop the beach from disappearing,” he said.

He added the project will be assessed by experts and a technical council as well as seminars on the effectiveness of the system.

He said construction on the system would be co妹妹enced in the fourth quarter of this year after earning approval from the technical assessment council.

In  二0 一 二, a group of hotels and resorts on Cửa Đại beach, in co-operation with partners in the Netherlands, proposed an underwater sea dyke as an emergency measure for the beach. But it failed to raise funds.

According to the latest report from Hội An City, more than  二0ha of beach washed away in  二00 九- 一 四, and the Cửa Đại Beach area saw sea encroachment of  五0- 二00m annually.

Nearly VNĐ 二00 billion ($ 八 million) was used to build sea dykes or temporary embankments with bamboo and sandbags, as well as the Geotube sandbag to protect the beach, but a section of dyke on Cửa Đại Beach was broken by rising sea water and waves in  二0 一 七.

Experts said the beach stretched  二00m just  一0 years ago, but now it has narrowed to  四0m due to rapid erosion and climate change. Nearly  七0 per cent of protective forest of Cửa Đại Beach was washed away by large waves, intense rains and a higher sea level since  二0 一 八.

A pristine stretch of sand spanning from An Bàng Beach to Cửa Đại Beach is a popular spot for foreign tourists in Hội An.
