Erosion situation at Thuan An beach

Erosion is complicated

At noon on October 23, at the coastal area through Hoa Duan residential group (Thuan An ward), although the tide had receded compared to October 22, the waves were still very high, continuously hitting the shore. Many large waves swept deep into the mainland, causing a 1km long stretch of coastline to seriously erode. In some places, the seawater eroded 50-70m deep, close to restaurants and tourist businesses of the people, with the risk of forming a "new sea gate" in this area.

Ms. Huynh Thi Thu, owner of a restaurant at Thuan An beach, said that she has been involved in the marine service industry for nearly 30 years, but has never seen erosion as complicated as in the past two years. “Fortunately, storm 12 dissipated offshore and did not make landfall directly. There was also an eel line built along the coast before the storm, which somewhat reduced the waves. Otherwise, my restaurant would have been swept away,” Ms. Thu worried.

Along Thuan An beach, many restaurants were buried in sand, garbage overflowed, and many buildings were damaged. Taking advantage of the time when the tide receded and the rain stopped at noon on October 23, some people took the opportunity to clean up and restore their business premises.

Due to the impact of storm No. 12 and high tides, in Vinh Loc commune, a 2km long coastline was also eroded 10-30m deep, directly affecting Provincial Road 21 and a number of essential infrastructure works. Not far away, in Tan An Hai village (Phu Loc commune), landslides continued to recur, creating a frog jaw that ate more than 1m into the mainland, threatening traffic and people's lives. This is an area that had a serious landslide of nearly 250m during last year's storm season.

Mr. Nguyen Van Hiep, Chairman of Phu Loc Commune People's Committee said: "As soon as the landslide was detected, the commune set up barriers, warned and asked people to limit their movement in dangerous areas, especially at night. Functional forces are always on site to promptly handle any arising situations. Right at noon on October 23, the commune transported rocks to reinforce the landslide sections, with the goal of not letting the situation become more complicated."

The most fundamental solution is to build a solid breakwater system.

Mr. Tran Dai Chien, owner of a restaurant on Thuan An beach, shared: "Every time the tide rises and the waves hit hard, everyone is scared. We hope the government will soon invest in a solid embankment that can withstand strong storms, so we can feel secure in doing business and developing tourism."

According to Mr. Le Dinh Phong, Chairman of Thuan An Ward People's Committee, the ward is focusing on monitoring weather developments, sending forces on duty regularly and propagating to people not to be subjective. "In the long term, the most fundamental solution is to build a solid breakwater system, similar to the section in Phu Thuan (old) or in Phong Quang Ward, to help stabilize the coast and protect tourism infrastructure," said Mr. Phong.

Sharing the same view, leaders of Vinh Loc and Phu Loc communes said that, in addition to temporary reinforcement measures, planting trees to block wind and sand, in the long term, there needs to be investment capital to build a solid embankment system. Localities will summarize the damage, propose to the city and relevant agencies to support capital, and soon implement anti-erosion projects.

Mr. Nguyen Dinh Duc, Director of the Department of Agriculture and Environment, said: “At Thuan An beach, the City People's Committee has approved an investment of about 200 billion VND to build an anti-erosion embankment, connecting from Phu Thuan embankment (old) to Thuan An beach, with a length of 1.4 km. The implementation period is 4 years, starting from 2026. For other erosion points, the department will continue to survey and propose appropriate solutions to ensure safety for residential areas and coastal infrastructure works.”

According to Mr. Duc, the Department of Agriculture and Environment continues to monitor the situation of landslides to take timely measures in dangerous landslide areas, affecting people's lives and property, essential infrastructure works...

Businesses in Thuan An take advantage of the time to clean up after the tide has receded compared to before.

In addition to building solid embankments, localities need to strengthen monitoring, early warning, and apply erosion forecasting technology; re-plan coastal spaces, and avoid spontaneous construction and encroachment on the water's edge. Coordination between departments and sectors in managing, investing, and exploiting coastal areas needs to be tightened to ensure both marine economic development and ecosystem and environmental protection.

At the same time, it is necessary to promote propaganda and raise public awareness about coastal protection; encourage people to participate in models of planting casuarina and sea cycad trees to block waves, and limit illegal sand mining. Along with that, research on soft embankment solutions, combining environmentally friendly materials in areas with suitable conditions, reducing negative impacts on natural flows.
