Research On Climate Heterogeneity Factors Affecting the Economic Development Through Negative Impacts on The Transport System Along the Coastal Rivers in The Mekong Delta

The Mekong Delta includes 12 provinces and one city with over 7,400km of roads including highways, national highways and provincial roads, excluding district roads, commune roads and 14,826km of inland waterway transport. The phenomenon of sea level rise, in addition to saline intrusion, causes desertification of cultivated land. It also affects riparian and coastal traffic works through issues such as inundation, destabilization of works, subsidence, and ground subsidence, high temperature causing cracking of the road surface, especially asphalt concrete roads, the phenomenon of wheel rutting, large and small potholes causing damage to the road surface, loss of traffic safety. Concrete structures, reinforced concrete, steel structures, rust quickly due to strong oxidation phenomena with high concentrations of Cl-, SO-2, CO-3, etc. ions in the air, saltwater intrusion is getting deeper and deeper inland. The groundwater exploitation due to lack of fresh water causes land subsidence. According to monitoring data in the Mekong Delta, the annual average subsidence rate is 5-7cm because the Mekong Delta itself is an area with a soft ground geology; so the subsidence will certainly destroy the industrial structures. The content of the article basically assesses the negative impacts of climate change on economic development through the assessment of the deterioration of the quality of traffic works, which is the basis of the special material manufacturing industry. Through the negative impacts of climate change, group of authors suggest timely prevention solutions.
