In Can Tho, floods in the morning and afternoon rush hours have made life in the city center upset and traffic difficult. Similarly, Vinh Long, Hau Giang, Soc Trang, Ca Mau provinces … the high tide accompanied by heavy and prolonged rains also causes a lot of damage, strongly affecting trade, business and agricultural production. Karma. In Soc Trang, the water rose, breaking 15 stretches of dikes, embankments and rural roads, and more than 70 hectares of crops belonging to the people of Cu Lao Dung were flooded. Ca Mau has about 16,000 hectares of summer-autumn rice submerged in the country …
However, according to Associate Professor Dr. Le Anh Tuan, Deputy Director of the Climate Change Research Institute (Can Tho University), the aforementioned severe flooding is caused simply by heavy rains from the effects of storms combined with the high tides. Lunar month of September. “The warning of the danger of a severe saline drought like the repeat of the 2019 dry season for people in the West is still there. People shouldn’t see a lot of flooded water but they have a subjective mindset, they need to be proactive in water storage solutions for production and daily life, ”said Associate Professor Dr. Le Anh Tuan and said that during the dry season , the situation of water intrusion Salinity intrusion in the Mekong Delta is largely dependent on flood water upstream of the downstream Mekong River. However, the prolonged drought in the upper Mekong River, especially in Upper Laos, northeast Thailand, coupled with the hydroelectricity of hydroelectricity has caused the water level of the Mekong River to continue at historically low levels. This makes water from the Mekong to Bien Ho very limited, while this is the main source of water for the Mekong Delta in the dry season.

Although in recent days, according to the Southern Regional Hydrometeorology Station, heavy rains occurred in lower Laos and northern Cambodia, but it was not enough to cover the water shortage from the upper Mekong to the lower. source. “Bien Ho is like a bag of water to regulate, store water in the rainy season and gradually release it to supply the Mekong delta downstream in the dry season, so when the amount of water stored here decreases, floods don’t they return. That is also a prognostic sign that saline intrusion will be fierce in the dry season, ”added Mr. Tuan.

Earlier, the Permanent Bureau of the Vietnam Mekong River Commission also said that by monitoring the flood level of the Mekong Delta in the second half of September 2020, the water level and total flood volume from the upper Mekong to the Mekong delta were low. most in the last 10 years.
