Commenting on the flood situation in the last months of 2020, Deputy Director of the National Center for Meteorological and Hydrological Forecasting Vu Duc Long said that large floods will focus on the last months of 2020 in the Central region, in the Rivers in this area are likely to appear 2-3 major floods, concentrated in the central and southern central provinces in October and November 2020. The flood peak in 2020, at the downstream of major rivers in Thanh Hoa and Nghe An will be alarming 1-alarm 2; rivers from Ha Tinh to Binh Thuan are at alert 2-alarm 3 and above alarm 3. On small rivers and streams, in the upstream areas, big floods, flash floods and landslides are likely to occur. “Starting from late September to October, November heavy rains will concentrate in the Central region, so there is a very high risk of large floods and especially large floods in this area from late September to early September. December this year, ”Mr. Vu Duc Long emphasized.
Sharing the advantages and disadvantages in forecasting as well as anticipating flood hazards, Mr. Long said that in recent years, he received the attention and investment of the State, the monitoring and transmission system information and forecast at the General Department of Meteorology and Hydrology has gradually modernized. Modern hydrometeorological forecasting models have been applied at the National Center for Hydrometeorological Forecasting as well as the Regional Hydrometeorological Forecasts, the Provincial Hydrometeorology Station, contributing to improving the quality of flood forecasting on river basins.
However, in flood forecasting and warning, there are still many difficulties such as climate change, more and more abnormal rain and flood events, plus topographic conditions in the Central region creating short rivers, The slope makes the water concentration time on the basins very fast, so the forecast time is often not long.
In addition, flood is the result of heavy rain, but forecasting rain, especially quantitative heavy rains, is still a challenge for the Hydrometeorology industry not only in Vietnam but also in the world.
In addition, at present, there are many hydroelectric and irrigation works built on river basins which completely change the flow regime on the river, causing many difficulties for flood forecasting and warning.
With the assessment that the rain and flood situation in 2020 will have many complicated developments, there is a very high risk of rain and heavy floods, so authorities and people need to continuously monitor and update the forecast reports. Hydrometeorological warnings are sent from the National Center for Hydrometeorological Forecasting, as well as on the mass media to get timely response plans, minimize possible losses caused by natural disasters, floods and rain.
The rule of the flood season in the Central region gradually translates from North to South, the flood season on rivers from Thanh Hoa province to Ha Tinh from July 1 to November 30; rivers from Quang Binh to Ninh Thuan province from September 1 to December 15. In July and August 2020, 1-2 small floods appeared on rivers in Thanh Hoa, Nghe An and from July 31 to August 2, on rivers in Ha Tinh, Quang Binh, one the flood wave, the flood amplitude of the rivers is about 3-6m, the flood peak at the upstream stations is at alarm level 1 and below alarm 1. Therefore, the flood season in the Central region appears according to the annual law. According to the data, in the early period of the flood season in 2020, the North Central region appears less flood and the flood peak is lower than the average of many years (the average of many years in this area in the period of July-August Usually 2-3 floods occur at alert 1 and above alert 1, there are floods with alarm 2).
In particular, in the past, there were big floods, historic floods like on Gianh river (Quang Binh) in early August 2007./.
