Why is Zhuozhou flooded?

The flood disaster in Zhuozhou is mainly related to its huge rainfall, special geographical location and imperfect drainage system.

1, heavy rainfall

Zhuozhou has a heavy rainfall, with an average rainfall of 398 mm, which exceeds the normal rainfall level. A large amount of rainfall led to the rapid accumulation of surface water, causing floods.

2. Special geographical location

Many rivers meet here, including BeiJuma River, Liuli River and Xiaoqing River. The upper reaches of these rivers are affected by typhoons and rainfall, and the water level rises rapidly and floods, causing the rivers in Zhuozhou to skyrocket. In particular, the maximum flood peak of incoming water in the upper reaches of the North Juma River reaches 4500 cubic meters per second, which exceeds the flood control capacity of Zhuozhou area.

3. The drainage system is not perfect

Because of the long continuous rainfall process, high precipitation intensity and wide coverage, the drainage system in Zhuozhou area can't bear such a large amount of water, which leads to a rapid increase in accumulated water. In addition, the topography of Zhuozhou area is relatively flat and the underground drainage is not smooth, which will also aggravate the flood situation.

How to prevent rainstorm:

1. Monitoring weather forecast: pay attention to the weather forecast at any time, know the possible time and place of rainstorm, and make preparations in advance.

2. Cleaning the drainage system: cleaning rainwater drains, sewers and pumps to ensure smooth drainage system and reduce the possibility of water accumulation.

3. Construction of flood control facilities: flood control facilities, such as dams, slope protection and river dredging. , should be built in areas vulnerable to floods.

4. Planning rational land use: avoid building houses and infrastructure in flood-prone areas, rationally plan urban land use, and reserve natural drainage channels.

5. Build water storage facilities: build reservoirs, ponds and other facilities to temporarily store rainwater during the rainstorm to reduce the pressure on the drainage system.
