Flood control refers to seven downs and eight ups.

Flood control refers to the period from late July to early August every year, which is the most concentrated period of precipitation in North China and Northeast China.

This period is a crucial period for flood control in northern China. Strong convective weather such as rainstorm and hail is mainly related to subtropical high. About 80% of the floods in the north are concentrated in the period of seven falls and eight rises.

Therefore, flood control mainly refers to the period from late July to early August in North China and Northeast China. It is necessary to strengthen flood control work to cope with possible extreme weather and floods. During this period, the people's governments and relevant departments in the relevant areas will take various measures, such as strengthening dike inspection, doing a good job in drainage, and organizing flood fighting and emergency rescue. To ensure the safety of people's lives and property and social stability.

It should be noted that flood control is not an absolute time period, but an approximate time period based on the experience of meteorological and flood control departments. In the concrete flood control work, it is necessary to make comprehensive analysis and scientific decision based on the local climate characteristics, geographical environment and actual engineering conditions.

Precautions for flood control:

1. Pay close attention to the weather forecast: pay close attention to the weather forecast of the meteorological department to get the latest weather situation, so as to take timely countermeasures.

2. Embankment inspection: Strengthen the inspection of river dikes, reservoirs and other water conservancy facilities, report and deal with dangerous situations in time, and ensure the safety of dikes.

3. Smooth drainage: For areas where water may accumulate, drainage channels should be dredged in advance to ensure that rainwater can be discharged in time to avoid flooding.

4. Reserve materials: reserve necessary flood control materials in advance, such as sandbags, lead wires, cement and wood. In case of emergency.

5. Avoid wading: During the flood, try to avoid wading, especially if you don't know the water depth and current.

6. Pay attention to safety warning signs: During the flood, pay attention to safety warning signs and don't go to dangerous areas to avoid accidents.
