Infrastructure Damage and Remediation Efforts

National Highway 1 Damage in Cần Thơ

A section of National Highway 1 in Cần Thơ, approximately 1 km long, has been severely damaged, exhibiting subsidence and waterlogging following recent high tides. This damage has remained unrepaired for several days, posing a significant risk to road users. One side of the road in the Đại Ngãi ward has been completely cordoned off with ropes due to deep subsidence and prolonged water accumulation. This forces vehicles traveling from Cần Thơ towards Cà Mau to merge into a single, narrow lane, creating a high risk of traffic accidents.

Irrigation System Devastation in Đắk Lắk

The recent floodwaters have also caused severe damage to the irrigation system in Đắk Lắk province. Crucial infrastructure responsible for irrigating approximately 26,000 hectares of rice paddies has been affected. Notably, the Tam Giang irrigation dam, a large structure on the Cái River, has sustained serious damage.

Tam Giang Dam Damage and Proposed Repair

Nguyên Linh reports from the Tam Giang Dam, a 60-year-old irrigation facility on the Cái River. The dam, spanning about 800 meters of cement construction with a three-tiered design, has been severely impacted by the flood. The spillway and other components are heavily damaged. The middle section of the dam's embankment has been eroded by the water, and the dike and drainage culverts are also in critical condition. The Đồng Cam One Member Limited Liability Company for Irrigation in Phú Yên province has proposed an urgent repair plan with an estimated investment of 10 billion VND.

Province-wide Irrigation System Losses in Đắk Lắk

Across Đắk Lắk province, numerous irrigation facilities have suffered severe damage post-flood. A total of 11 irrigation projects have been affected, with estimated damages exceeding hundreds of billions of VND. The Provincial People's Committee of Đắk Lắk has directed relevant departments to assess the damage and provide financial support for repairs to mitigate the consequences of the flood on the provincial irrigation system.

Road Damage and Community-Led Solutions in Đắk Lắk

Beyond irrigation systems, many roads in Đắk Lắk province are also damaged and broken following the recent historic flood. Mountainous road sections are at risk of further landslides. Despite these challenges, local communities are implementing measures to ensure people's mobility, particularly for children attending school.

Innovative Access for Students

In one instance, residents have created makeshift pathways and erected wooden ladders to facilitate students' access to school in the central commune. For the past week, nearly 20 students from the Phong Thái and Tư Thạnh hamlets in Tuy An Tây commune have been transported to school twice daily by their parents using this method. Heavy rains on November 19th caused severe landslides on the rural transport route connecting Phong Thái and Tư Thạnh. At one location, the road is completely broken, with one lane subsiding up to 3 meters from its original position. This is the sole access road to the schools in the hamlet.

A resident stated, "We had to build a ladder for our children and the three teachers to go, and then shuttle them. There are no vehicles that can pass. Even motorcycles can't go, only walking. So, given this situation, we hope the road will be repaired soon for the convenience of the people."

Several areas around this location have experienced significant landslides, cutting off transportation. Despite these difficulties, students' access to education remains uninterrupted. On the inter-hamlet and inter-commune road, approximately 10 km long, passing through Tuy An Tây commune, there are four landslide points. In some sections, about 300 meters of concrete road have collapsed down the hillside. Residents have had to create temporary paths through agricultural land to transport food and essential supplies. Another resident commented, "In other places where there are landslides, there are bulldozers to clear the road, and students can go, motorcycles can go. But here, the landslide is so severe that people cannot go at all, so they have to go through other people's land."

The total damage to transportation infrastructure in Đắk Lắk due to the floods amounts to over 817 billion VND. The estimated time for repairs is extensive. While awaiting permanent infrastructure, these temporary solutions are crucial for maintaining community life and ensuring children can continue their education.

Ongoing Weather Threats and Warnings

The safety of children traveling to school requires adult supervision due to the persistent risk of landslides. Central Vietnam is currently experiencing another period of heavy rainfall. Last night and this morning, some areas recorded rainfall exceeding 100 mm. This heavy rain is expected to continue until tomorrow night. Mountainous regions are warned of potential landslides.

Rainfall Forecast and Landslide Risk

This afternoon and tonight, rainfall will be concentrated in the southern part of Quảng Trị province down to Đà Nẵng city, and in the eastern parts of Quảng Ngãi province to Đắk Lắk and Khánh Hòa. Moderate to heavy rainfall is forecast, with amounts ranging from 40 to 100 mm, and locally very heavy rainfall exceeding 150 mm. Tomorrow, the rain area will shrink to the southern part of Quảng Trị down to Quảng Ngãi, with some localized areas still experiencing very heavy rainfall above 150 mm. Heavy rainfall on weakened soil and rock layers will increase the risk of flash floods and landslides on the slopes of hills and mountains in these areas.

Northern Vietnam Weather Update

In Northern Vietnam, strengthening cold air will bring rain and cold temperatures this afternoon and tonight. Nighttime temperatures are expected to drop to 15-18°C, and in mountainous areas, to around 13-15°C, with some places falling below 12°C.

Synthesis/Conclusion

The transcript highlights the severe impact of recent heavy rainfall and high tides on critical infrastructure in Vietnam, specifically focusing on road networks and irrigation systems. In Cần Thơ, a section of National Highway 1 is rendered dangerous by subsidence and waterlogging, forcing traffic into a single lane. Đắk Lắk province faces extensive damage to its irrigation infrastructure, including the significant Tam Giang Dam, with estimated losses in the hundreds of billions of VND. Furthermore, road damage in Đắk Lắk, particularly in mountainous areas, has led to landslides and road collapses, disrupting transportation and isolating communities. In response to these challenges, local communities are demonstrating resilience by implementing temporary, innovative solutions, such as building ladders for students to access schools, while awaiting permanent repairs. The economic impact is substantial, with over 817 billion VND in damages to transportation infrastructure in Đắk Lắk alone. The situation is compounded by ongoing weather threats, with warnings of further heavy rainfall and increased landslide risk in Central Vietnam, alongside a cold air surge bringing rain and lower temperatures to the North. The need for swift and effective infrastructure repair and mitigation strategies is paramount to ensure public safety and economic stability.
