HCM CITY — Several sea dyke sections in the Cuu Long (Mekong) Delta provinces of Bac Lieu and Soc Trang have collapsed because of high tides and strong waves.

In Bac Lieu Province, water broke through several sections of Ganh Hao Sea Dyke in Dong Hai District early last month, causing sea water to flow into residential areas.

Nguyen Van Be, who has lived near the dyke for 40 years, said he had never seen such strong waves.

"If there are no prompt preventive measures, the property and lives of local people will be threatened," he said.

About 1,000 people live near Ganh Hao Sea Dyke.

Lai Thanh An, head of the office of the Bac Lieu Province Steering Committee for Flood and Storm Prevention and Control, Search and Rescue, said the collapse of section of the dyke damaged 700 sq.m, with a cost of VND2.5 billion (US$113,000).

The section has been temporarily reinforced.

Luong Ngoc Lan, director of Bac Lieu's Department of Agriculture and Rural Development, said the erosion of the dyke was unusual this year because of the impact of inclement weather.

"We have worked with the Central Irrigation Department to survey and seek measures to consolidate Ganh Hao Sea Dyke," he said.

The department has petitioned the Central Steering Committee for Natural Disaster Prevention and Control to support the province VND20 billion ($90,000) to fix the dyke.

In Soc Trang Province, a 50-metre section of Vinh Chau Sea Dyke in Vinh Chau Town's Vinh Hai Commune broke because of high tides and strong winds last week.

Authorities and local people reinforced the collapsed section.

However, the section and other sea dykes in the commune need to be upgraded, said the Vinh Hai Commune People's Committee.

Cajuput forests outside Vinh Chau Sea Dyke have been lost, which could lead to the collapse of dykes by high tides and strong winds.

Several erosion sites have caused damage to the dyke foundation, which could lead to a collapse when there are high tides, according to the Vinh Hai Commune People's Committee.

The Vinh Chau Sea Dyke, which runs from the My Thanh 2 Bridge to the border with Bac Lieu Province, belongs to a Government programme to upgrade the sea dyke system from the central province of Quang Ngai to the Mekong Delta province of Kien Giang.

Under the programme, the upgrading of Vinh Chau Sea Dyke will be completed in the 2016-20 period. The dyke will cost a total of VND430 billion ($19 million).

The Soc Trang Province People Committee has assigned the Vinh Chau Town People's Committee to focus on consolidating Vinh Chau Sea Dyke's important sections. — VNS
