Through many field inspections of the flooded section in Song Phan commune on the Phan Thiet - Dau Giay highway, as well as organizing meetings between departments, branches and local authorities to analyze and find the cause of the flooding.
On August 6, the Thang Long Project Management Board and related units determined that the initial (temporary) cause of flooding on the expressway was due to the change in the flow of the Phan River. “Above the flooded section, the Phan River has a section of trees growing in the middle of the river, especially some large trees that block the flow when there is unusually heavy rain. When a lot of water flows upstream, the blocked flow will change the flow, leading to water overflowing onto the expressway…”, said the Thang Long Project Management Board. Therefore, the immediate solution is to clear the flow of the Phan River by clearing away the trees that block the flow. On the other hand, the related units will invite experts to recalculate the flow basin as well as review the issues through surveys and local suggestions to find a long-term solution… The Thang Long Project Management Board also stated that because when designing, the related units did not carefully calculate the flow of the Phan River, the cost of the solution will be the responsibility of the design unit.
