There needs to be a fundamental solution to prevent landslides on the embankment of Nhu Nguyet Street.

The issue of protecting the embankment of Nhu Nguyet Street has been raised many years ago, but until now Da Nang city still has not had an effective solution.

Severe landslides due to high tides

On the afternoon of October 22, although storm Fengshen (storm No. 12) did not enter the city, with high tides at the foot of Thuan Phuoc bridge, Hai Chau ward, 4-5m high waves continuously hit the shore, causing the sidewalk tiles on Nhu Nguyet street to break, the waves ate deep into the concrete embankment, creating deep holes and collapses.

Mr. Le Tan Phat, who lives next to Nhu Nguyet Street, said that the embankment has never been as severely eroded and eroded as this year. If there is no solution soon, the embankment will collapse, and the road will be difficult to maintain.

Sharing the same opinion, Mr. Nguyen Van Tai, a resident living inside Nhu Nguyet Street, said that from the afternoon of October 21 to noon of October 22, many large waves appeared, causing seawater to flood into people's houses.

Meanwhile, Mr. Tran Van Chung, a retired official, shared that every year, when the Northeast monsoon and storms come, this embankment is often damaged. And every year, the city spends tens of billions of dong to repair it. Once it is completed, it is damaged again the next year. But the problem that people wonder is why the repair was not done sooner but waited until mid-September 2025 for the contractor to start construction, causing the work to be damaged again while it is still in progress...

According to the reporter's records, there were 4-5 damaged embankments and sidewalks, some sidewalk sections were washed away by waves several meters deep, many sidewalk tiles were broken. The authorities had to fence off this area to protect people's safety. On Nhu Nguyet Street, a construction unit was reinforcing the embankment. The construction work was forced to stop because the waves were too big.

Previously, on the afternoon of October 22, Vice Chairman of the City People's Committee Le Quang Nam led a working delegation to inspect the embankment and sidewalk of Nhu Nguyet Street that had been severely eroded by waves; at the same time, he directed the embankment construction unit to concentrate forces and materials, so that after the storm ended, the damaged embankment and sidewalk could be repaired immediately. However, following storm No. 12 were prolonged heavy rains, causing serious flooding and water overflowing on Nhu Nguyet Street, so the repair work was temporarily suspended.

Need fundamental solutions

According to irrigation expert Huynh Van Thang, former Deputy Director of the Department of Agriculture and Rural Development of the old Da Nang city, this is the "wind throat" position at the mouth of the Da Nang river, only strong northeast wind will cause high waves. Previously, the Department of Irrigation built Thuan Phuoc embankment to protect, but due to the large waves, the form of paving bricks on mortar (M75 concrete or crushed stone) could not withstand.

Therefore, it is necessary to have a solid solution, standard design, calculate the wave area, and strike. At the same time, conduct a field survey, determine the dangerous areas on the floor and yard to peel off, clean, arrange steel reinforcement and pour M300 thick concrete, then the possibility of limiting damage is high. However, in the long term, it is necessary to make an overall assessment based on scientific arguments, paying special attention to factors such as climate change, extreme weather, and encroachment speed of the flow, etc.

According to the city's Department of Construction, the damage to the embankment of Nhu Nguyet Street is increasingly complex in extent and scope. This situation has occurred since 2017, due to the impact of construction projects causing waves to travel deep into the Han River estuary, at the same time as the impact of sea elements during the Northeast monsoon season, which suddenly increases or combines (big waves and high tides).

The embankment of Nhu Nguyet Street is also one of the important routes running along the Han River, playing a role in protecting the infrastructure and residents inside Hai Chau Ward. However, the embankment is currently designed to not withstand the conditions of waves and tides exceeding the design. The embankment is often affected by storm waves, posing a serious risk to the safety of infrastructure works and landscapes along the Han River. Therefore, the Department of Construction has advised the city leaders to implement the project to renovate the embankment and sidewalk of Nhu Nguyet Street.

Specifically, the former Department of Transport (now the Department of Construction) conducted a survey, collected opinions from experts and units; and advised the People's Committee of Da Nang City on solutions to overcome the problem. Accordingly, the project to overcome the impact of storms, high tides, and the impact of sea waves on Nhu Nguyet Street was approved by the City People's Committee and started construction on September 3, 2025 with a total investment of more than 12.4 billion VND.

Currently, the main solution being implemented is to renovate the embankment with a "wave deflector", thereby repairing the damage to the existing embankment wall and sidewalk, renovating and peeling off part of the concrete of the top wall, extending the steel, raising the wall's top level; building a wave-breaking wall to reduce waves from overflowing the embankment's top, the embankment's top level is 2.9m. The wave-breaking wall has a reinforced concrete deflector structure with steps and railings. The repair of damaged sidewalks uses a concrete structure with a color that is poured in place to match the existing brick color to save costs, ensure safety and urban aesthetics. At the same time, the Department of Construction prioritizes research and application of new technologies and new materials.

Through general assessment, the constructed seawall sections have been effective in reducing the impact of wave run-up on infrastructure along Nhu Nguyet Street. The project is expected to be completed soon, reducing damage caused by adverse weather, ensuring urban aesthetics and infrastructure.
