How to correctly prevent and avoid sudden floods?

To understand the prevention and avoidance measures of sudden floods, we must first understand the causes and types of floods. Let's briefly introduce how to prevent and avoid sudden floods from the perspective of classified discussion.

Floods can be divided into the following types according to their causes: 1, rainstorm flood 2, mountain flood 3, debris flow 4, dam-break flood 5, snowmelt flood 6 and ice flood.

1. Predictable floods caused by weather factors

Rainstorm flood, snowmelt flood and ice flood are greatly influenced by climate and season. Before this type of flood comes, we can make predictions through weather and season and take preventive measures in advance. In case of continuous rainstorm, warming temperature and melting rivers, we should be vigilant and protect personal safety and property safety. When the flood comes, you should calmly choose the evacuation location according to the geographical and topographical conditions of your house. If it is too late to move, it is necessary to quickly move to nearby hillsides and highlands. Sufficient drinking water and daily necessities should be reserved if conditions permit.

Second, unforeseen sudden floods.

Floods caused by sudden accidents, such as the collapse of reservoirs or rivers, are sudden and unpredictable. There are many reasons for dam break, most of which are caused by earthquakes. It may be that the dam is in disrepair and loose for a long time, and the water volume in the dam suddenly increases and the pressure increases, which leads to the dam rupture; It is also possible that there are many holes in the dam, such as ant holes and mouse holes, and water seepage and leakage are not found in time, which leads to the collapse of the dam.

The dam-break flood is fierce and the head is high. If it is too late to escape, you can climb to the top of the building or climb tall trees for temporary escape. Dam-break floods are generally fierce, but they also fade quickly, and the water surface can survive after falling and fading. If you are in the water, just hold your horses and try to catch the floating board and furniture. Stay away from wires and telephone poles, try not to swim in the flood, and wait for the opportunity to ask for help.

The key to prevent dam-break flood is to strengthen inspection, find hidden dangers and strengthen treatment. At the same time, strengthen the monitoring of floods and water conditions, adopt 24-hour shift monitoring, and promptly inform the masses to evacuate quickly.
