What are the methods for urban flood control

The main methods for urban flood control include the following:

1. Pay attention to warnings and take preventive measures in advance:

Pay attention to receiving the rainstorm and ponding warning information issued by the meteorological and water departments.

Take protective measures in advance for low-lying residential areas, shopping malls, garages, etc., and build water retaining dams with door panels, sandbags, etc

2‌. Evacuate to a higher place:

Generally, shelters are chosen in places that are close, have higher terrain, convenient transportation, and better hygiene conditions, such as flat roofs of high-rise buildings, schools, hospitals with higher terrain or solid buildings, etc

3‌. Stay away from electrical equipment:

Stay away from electrical facilities to avoid danger caused by electrical leakage. If you encounter a broken wire stuck in water on the ground, quickly move away.

If there is waterlogging at home, the power supply and gas valve should be cut off in a timely manner

4. Pay attention to flood prevention signs and do not walk in stagnant water:

Do not walk on roads with accumulated water, pay attention to roadside flood safety warning signs, do not approach areas with eddies, and prevent falling into dangerous areas such as deep wells and pits with missing manhole covers

5. Driving precautions:

Drive the car to a relatively safe place and try to park in a higher terrain.

When driving through flooded roads, one should pay close attention to flood warning signs and avoid venturing into water.

On sections with unknown water depth, one should disembark and explore or detour, and not blindly force traffic.

If the car stalls in deep water, do not restart it to prevent water from entering the engine; When the accumulated water outside the car deepens further, it is necessary to evacuate in a timely manner

6‌. Dealing with waterlogging:

Residential areas in low-lying areas can place sandbags, barriers, or stacked walls at the entrance in advance.

When water accumulates indoors, check the electrical facilities in the home in a timely manner, cut off the power immediately, and prevent electric injuries caused by water accumulation. When the water in the house is too deep, evacuate quickly and search for a high point to wait for rescue.
