What is flood alarm level 2?
According to Article 3 Decision 05/2020/QD-TTg stipulating the principles for flood alarming leveling in Vietnam:
Article 3. Principles for flood alarming leveling
Flood alarm levels are the classification of flood severity. Each flood level is determined through a corresponding water level value specified at hydrological stations on rivers and streams, reflecting the severity of the flood and the level of inundation caused by the flood.
Flood alarm levels are divided into three levels based on the characteristics, magnitude of flood water levels, and the impact of floods on the safety of dykes, banks, river beaches, structures, and the socio-economic conditions in the area.
Under the above provisions, flood alarming is divided into three levels: alarm level 1, alarm level 2, and alarm level 3, based on the characteristics, magnitude of flood water levels, and the impact of floods on the safety of dykes, banks, river beaches, structures, and the socio-economic conditions in the area.
Thus, Flood alarm level 2 is the threshold level indicating that the flood in the river has reached a medium level, with floodwaters beginning to cause inundation and negative impacts on the livelihoods, economy, and society - equivalent to an average flood.
