At the meeting, a representative of Construction Consulting Joint Stock Company 533 said that the 2.5x2.5m drainage culvert was designed and built based on calculations, based on the investigation of the flow, water level of the Phan River and the flood peak in 1992 in the locality. The design of the existing bridge and culvert is consistent with the flood flow characteristics of TCVN 9845 - 2013 standard and the handbook of hydraulic calculations of bridges and roads.

Representatives of the consulting unit and the management board of the Phan Thiet - Dau Giay expressway project reported at the meeting.

Faced with the local flooding at Km25+419, representatives of sectors, localities and units also proposed solutions to determine the cause and measures to overcome the flooding situation in the coming time. In particular, it is important to review the current status of the area, re- examine the Phan River cross-section, and the level of sedimentation on the Phan River. At the same time, survey the terrain, hydrology, collect rainfall, take aerial photos to determine tree density to calculate the possibility of affecting the flow... from which to have long-term, sustainable measures to thoroughly resolve the local flooding situation on the highway.

Concluding the meeting, Mr. Nguyen Quoc Nam - Director of the Department of Transport requested the Thang Long Project Management Board to have a plan to handle if the water level rises on the highway. Take the lead in coordinating with departments, branches and localities to survey and immediately in August (no later than August 15) to dredge and clear the flow on the Phan River. Coordinate with consulting and design units to survey the terrain and hydrological survey to have a long-term and sustainable plan as soon as possible. Regarding its responsibilities, the Department of Transport will continue to monitor the situation, coordinate with units, branches and localities to propose measures to continue handling, and report to the Provincial People's Committee for direction.
