Knowledge of flood control
Flood season:
The flood season refers to the period when the water level of a river rises seasonally due to seasonal precipitation, ice melt and snow melting in the basin.
Heavy precipitation:
Heavy rainfall refers to the rain with great precipitation intensity, which is generally called "heavy rain" or "heavy precipitation" in meteorology, which has the characteristics of heavy rainfall, obvious extremity, and high risk of disaster, and is prone to flood disasters, landslides and debris flows in some areas.
Flood control:
To prevent and mitigate flood disasters, relevant work has been carried out in flood forecasting, flood control scheduling, and the application of flood control projects. The meaning of flood refers to the seasonal or periodic rising water phenomenon of rivers, lakes and other waters.
01How to classify the rainstorm warning signal?
01 Red Alert: More than 100 mm of rain will fall within 3 hours, or it has reached more than 100 mm and the rain is likely to continue.
02 Orange Warning: More than 50 mm of rain will fall within 3 hours, or it has reached more than 50 mm and the rain is likely to continue.
03 Amber Alert: More than 50 mm of rain will fall within 6 hours, or it has reached more than 50 mm and the rain is likely to continue.
04 Blue Alert: More than 50 mm of rain will fall within 12 hours, or it has reached more than 50 mm and the rain is likely to continue.
02What kind of disasters are prone to accompany the flood season?
Lightning disaster
Lightning is a discharge phenomenon accompanied by lightning and thunder, which can cause casualties, fires, or system failures such as power and communications. In case of thunder and lightning, it is strictly forbidden to stay on the top of the mountain or in the high hill area; Don't hide under lightning rods and large trees; Don't use umbrellas in open areas, don't make phone calls; Close the doors and windows indoors to prevent lightning from hitting the room directly and spherical lightning drifting into the room, unplug the power supply, telephone lines, etc., and stay away from the metal water pipes entering the house.
Flood disasters
The amount of precipitation exceeds the capacity of rivers and lakes, resulting in a sharp increase in water volume and a sharp rise in water levels, resulting in the loss of normal life and production activities. In case of heavy rain and flooding, you should quickly judge your surrounding environment and move to a mountain or higher place as soon as possible; Find some floating materials such as door panels, tables and chairs, wooden beds, and large pieces of styrofoam to make a raft to escape; Do not swim to escape, do not climb live poles, towers, stay away from inclined poles and broken wires; If you have been caught in a flood, be sure to hold on to something fixed or floatable as much as possible and look for an opportunity to escape.
Gale damage
It mainly damages houses, trees, crops, vehicles, ships, communication facilities, and power facilities. In case of windy weather, do not stay under billboards or temporary buildings to take shelter; If you are driving, you should drive into an underground parking lot or shelter; Stay away from the window to avoid strong winds sweeping sand and gravel breaking through the glass and injuring people; Agricultural production facilities should be strengthened in a timely manner, and mature crops should be harvested as soon as possible.
Geological hazards
Geological disasters such as landslides, landslides, and debris flows are prone to occur during the flood season. In the event of such a disaster, flee to the sides of the stable mountain, not to flee above or below, and not to take shelter under steep slopes or climb into trees.
03What are the safety knowledge during the flood season?
1. Close doors and windows, stay at home.
2. Low-lying land, power cut.
3. When the wire falls, the alarm will be given.
4. In case of flooding, climb the heights.
5. Leave the river to prevent flash floods.
6. Please detour through the underpass.
7. Rain and fog lights, slow down.
What should I do if the vehicle accidentally stalls in standing water? 】
When the visibility is less than 100 meters in heavy rain, the low beams, marker lights, front and rear position lights and hazard warning flashing lights should be turned on, and the speed should not exceed 40 km/h. In the unlikely event that the vehicle stalls, the ignition switch should be turned off immediately and the key should be pulled out. If the water is too deep, do not stay in the car and go to a safe place to ask for help.
04What preparations do I need to make during the flood season?
Stay on top of disaster forecasts
Listen to the weather forecast frequently, pay close attention to weather changes, understand and grasp the disaster forecast and prediction, and do a good job in flood protection.
Learn about flood control
Conscientiously study the knowledge of disaster prevention and resilience during the flood season and improve self-protection ability.
Avoid hazardous activities
Try not to go out in case of disastrous weather, and find a safe place to avoid disasters and protect yourself if you have gone out. Do not stay in areas prone to flash floods (river, beach, low-lying places); Do not stay in dangerous areas or dilapidated houses prone to landslides, collapses and mudslides; If you need to cross the river, you should find a bridge to pass through, do not wade through the pit, cross the stream, cross the river, and do not risk crossing the river.
