How to prevent a new round of heavy rainfall this time？

　　CCTV News:At 12: 00 on the 21st, the Henan Flood Control and Drought Relief Headquarters started the flood control level II emergency response; On the afternoon of the 22nd, Henan Meteorological Observatory and Zhengzhou Meteorological Observatory successively issued red rainstorm warnings.　

　　Henan: Flood control level II emergency response exceeds 20 rainstorm red warnings.

　　The Meteorological Observatory predicts that the strongest rainfall period in Henan will be from noon on the 22nd to midnight before the 23rd. The Meteorological Observatory predicts that the accumulated precipitation in Pingdingshan, Luohe and Xuchang, southern Zhengzhou and Kaifeng, northern Nanyang and western Zhoukou will reach more than 100 mm today.

　　70 high-speed trains stopped and 3 through trains turned back.

　　Affected by rainfall, as of noon on the 22nd, Zhengzhou East Station stopped trains for 70 times. Heavy rainfall causes Lanzhou to pass through the pipeline — Beijing West Z130 and other 3 through trains turn back.

　　The five-hole floodgates of Changzhuang Reservoir are all open.

　　At 2: 00 pm on the 22nd, the rainstorm passed through Zhengzhou Changzhuang Reservoir, and the reservoir was prepared in advance.

　　Henan Taiwan reporter Ceng Tao:It’s 2 o’clock in the afternoon, and we can see that it’s raining harder and harder. As can be seen from the lens, at present, the five-hole floodgates of Changzhuang Reservoir have all been opened. Looking in along the floodgates, Changzhuang Reservoir has vacated its storage capacity to cope with this rainstorm.　

　　The level I emergency response in the two places has been shut down in many places.

　　In order to cope with the impact of heavy rainfall, Henan made full preparations in advance.

　　The first is to stop work and stop production notice. Xingyang City, Zhengzhou and Changyuan City, Xinxiang launched Class I emergency response to flood control on the 22nd, requiring all outdoor operations to be stopped, shops along the street and underground shopping malls to be closed, and scenic spots, dangerous roads and underground culverts in the jurisdiction to be closed.　

　　Zhengzhou also requires the city’s buses to stop running, construction sites to stop outdoor operations, all tourist attractions to be temporarily closed, and shops along the street to stop business until 8 am on the 24th. Schools, kindergartens and training institutions at all levels should stop all activities such as offline teaching, summer training and summer camps.

　　Kaifeng also issued a notice that buses were temporarily suspended and stores along the street were closed. All trains in Jiaozuo Railway Station were temporarily suspended for one day from 0: 00 on the 22nd.　

　　Close the concave interchange of underground space bridge and culvert tunnel in time.

　　In order to prevent waterlogging from threatening people’s lives and property, underground spaces, bridges and culverts, tunnels and underpasses were closed in time. Zhengzhou Metro has placed sandbags for flood control and installed waterproof baffles at the entrance. The entrances and exits of eight tunnels in Zhengzhou have been equipped with disconnection facilities, isolation guardrails have been prepared, and special personnel have been arranged to be on duty. Once the tunnel is seriously flooded, it will be disconnected immediately. As a main trunk line running through the north and south of Zhengzhou City, the Beijing-Guangzhou Expressway under the tunnel was closed at 11 am on the 22nd, and vehicles and pedestrians were prohibited from passing. In addition to personnel protection, rescue equipment such as kayaks, forklifts, and emergency power vehicles are also waiting.

　　Save for a rainy day, stop at the shops in the highlands for flood prevention.

　　In addition, vehicle safety is also taking precautions. Zhengzhou Flood Control and Drought Relief Headquarters reminded everyone in an open letter to the public yesterday to move the vehicles in the underground garage to the road heights. All organs, enterprises and institutions near the community will be unconditionally open to the public free of charge. From the 21st, citizens in Zhengzhou and Kaifeng began to drive their cars out of underground garages and park in higher places. On the 22nd, the official micro of Henan Traffic Police announced that the traffic police department said that vehicles temporarily parked on roads, viaducts and other places due to emergency flood control would not be dealt with illegally.

　　Henan Weihui also issued an urgent reminder: shops along the street should reserve raincoats, rain boots, buckets, flood control sandbags, etc. in advance; Residents on the first floor should prepare enough daily necessities and go to the second floor to avoid danger.

　　At present, Zhengzhou Meteorological Observatory has lifted the red rainstorm warning. According to the meteorological information released by Henan Meteorological Bureau at 9: 00 pm on the 22nd, from the night of 22nd to the morning of 23rd, there were heavy rains in Shangqiu, Kaifeng, Zhoukou and Zhumadian, the eastern part of Nanyang area and the northwest part of Xinyang area, and some heavy rains were accompanied by strong convective weather. Everyone should take precautions. In addition to Henan, Sichuan, Chongqing, Shaanxi and other places also ushered in a new round of heavy rainfall on the 22nd and 23rd. In the face of geological disasters such as urban waterlogging and mountain torrents that may be caused by such extreme weather, all localities are also in emergency rescue.

　　The Central Meteorological Observatory predicts that in the three days from the 22nd, heavy rainfall will be concentrated in the south of Shaanxi, Sichuan Basin, Huanghuai, Jianghan, Jianghuai and Northeast China.

　　Sichuan upgrades rainstorm warning, and many streets in Langzhong City accumulate water.

　　At 16: 00 on the 22nd, the Sichuan Meteorological Observatory upgraded the blue rainstorm warning to the yellow rainstorm warning. In Langzhong City, Nanchong, Sichuan Province, there was a thunderstorm at around 3 am on the 22nd. Continuous rainstorms have caused many streets in the city to accumulate water, and landslides, falling rocks and mudslides have appeared in many roads in China and provinces. Eighteen towns (streets) in the city have been affected to varying degrees, and 2,516 people have been safely transferred.

　　Shaanxi: There is heavy rainfall in 106 counties, and Mian County has the largest rainfall.

　　From the 21st to the early morning of the 22nd, there were rainy weather in 106 counties and districts in Shaanxi province, and six rivers, including Ankangchi River and Shangluo Ganyou River, experienced super-alarm floods. There have been heavy rains in many places in Hanzhong, Shaanxi Province, among which Mianxian County has the largest rainfall, reaching 220 mm. The continuous heavy rainfall has caused the water levels of many rivers in Mianxian County to skyrocket, and some houses in Mianyang Street, Wuhou Town, Chadian Town, Zhoujiashan Town, Xinpu Town and other towns in Mianxian City have been flooded and people have been trapped. Local firefighters urgently mobilized vehicles and assault boats to rescue, and successfully transferred more than 300 trapped people to a safe area.

　　The National Defense General maintains flood control level III emergency response.

　　On August 22nd, the National Defense General maintained the Class III emergency response to flood control, and sent an additional working group to Shaanxi to assist in flood prevention in the upper reaches of the Hanjiang River. The National Defense Office and the Emergency Management Department discussed and judged with the China Meteorological Bureau and the Ministry of Water Resources, and the dispatch reminded Henan, Shandong, Shaanxi, Hubei, Sichuan, Chongqing and other provinces to do a good job in flood prevention and response, promptly and decisively transfer people in dangerous areas, strengthen the inspection of flood control projects, and grab and protect them in time when danger is found. Fire rescue teams from all over the country responded quickly and assembled efficiently.

　　Every summer, heavy rainfall will cause secondary disasters and even casualties in some areas. However, as a common weather phenomenon, heavy rainfall will still exist in our daily life for a long time, so what can the managers of our city do to better prevent the rain in the future?

　　It is difficult to predict instantaneous heavy rainfall.

　　On the evening of 16th of this month, a heavy rainfall in Beijing caused water accumulation in many sections, especially in some culverts under the bridge due to heavy rainfall in a short time.　

　　Liu Jiahong, Senior Engineer, China Academy of Water Resources and Hydropower Research:On the one hand, it is extremely short-term heavy rainfall, which is not particularly large in the whole city. It may be concentrated in the bridge area, causing very rapid water accumulation.

　　Upgrading drainage capacity of drainage pipeline in response to heavy rainfall

　　At present, the forecast of short-term heavy rainfall is still a worldwide problem, but does this mean that we are helpless when dealing with short-term heavy rainfall? Liu Jiahong, a senior engineer of China Academy of Water Resources and Hydropower Research, introduced that after the "July 21" torrential rain disaster in Beijing in 2012, relevant parties further optimized the "one bridge, one policy" and other schemes in 146 lower concave bridge areas in Beijing. The method of effectively relieving the accumulated water in the concave bridge area by digging and regulating the reservoir has been applied in many bridge areas.

　　When the drainage conditions are limited, it is necessary to coordinate and solve the drainage problem.

　　However, due to the surrounding facilities such as subway stations, the location involved is limited in the renovation of storage facilities. The drainage pipe network in the surrounding community will even discharge more water into the concave bridge area. Then, how to solve the problem of urban drainage under the condition of limited drainage conditions?

　　Liu Jiahong, Senior Engineer, China Academy of Water Resources and Hydropower Research:Limited drainage conditions is a historical debt in the process of urban development, which needs to be solved in coordination with surrounding areas (such as the sunken bridge area with insufficient conditions), to see if the surrounding green space has built land to lower the conditions of storage pools, and then to lower the storage pools in these surrounding areas by building land, so as to buffer some of the accumulated water in the rainstorm and avoid generating particularly great instantaneous pressure on the bridge area.

　　Real-time warning of smart water conservancy and waterproof by water accumulation map

　　Turning to Henan, Zhengzhou, Henan Province, which just experienced the "July 20" torrential rain, made many countermeasures in advance in the face of this round of heavy rain. The official WeChat of Zhengzhou Traffic Police provides citizens with safe haven reference by counting 42 water accumulation points in the city. In Ningbo, Zhejiang Province, in response to the typhoon "Fireworks" at the end of July, an electronic map of stagnant water with real-time updated data was launched urgently, so that citizens can check the stagnant water situation at key points in the city at any time. Earlier in 2013, there was also a "water accumulation map" jointly launched by the multi-site flood control office and the traffic police to mark the degree of water accumulation in different colors. So, will the waterlogging map be a sharp weapon to deal with urban floods?

　　Liu Jiahong, Senior Engineer, China Academy of Water Resources and Hydropower Research:Water accumulation map is a very effective means to remind the public of risks, but in order to ensure the validity, reliability and accuracy of data, a professional team is needed. At the same time, it is real-time, but it has no forecasting function. Only when there is accumulated water can the data be uploaded to the platform. If we can combine the accumulated water map with the weather forecast, it should be more valuable for residents’ travel and route planning.

　　Improve the emergency response mechanism, and all departments form a joint force for flood control

　　In the opinion of experts, the emergency response of government departments after the release of early warning information is very important. The red rainstorm warning is only an administrative guidance issued by the meteorological department, which has no mandatory execution, and is often too broad and general for the public to understand its connotation. The meteorological warning only sounded an alarm, and then all government departments need to quickly form a consultation and linkage mechanism and start their own specific emergency measures, so as to set up an effective protection umbrella as soon as possible.　

　　Wang Jiazhuo, Dean of Ecological Municipal Institute of China Urban Planning and Design Institute:All departments should have plans for the disaster of rainstorm, such as what hospitals should do, what our communication, transportation, subway and electric power departments should do, and they should be able to respond in time when an incident occurs. At the same time, these departments should also be linked with each other, and emergency management departments should play some roles in the coordination of emergency management of such departments.

　　[CCTV Short Comment] "Much thunder and little rain" will also be moved by the news of "flood season"

　　There is a good saying: "natural disasters are not caused by people, and disasters are not caused by heaven." To deal with the flood, we should take more initiative, even if "much thunder and little rain", we should keep our eyes open and look like an enemy; What’s more, it’s more important to move when you hear about the flood season, and it’s just the saying that "it’s better to be on the safe side than to be on the safe side." Flood control and flood fighting, on the surface, test the emergency level of various departments, in fact, test the city’s governance capacity. The report of the 19th National Congress of the Communist Party of China emphasized the need to improve the public safety system. Really consolidate the value coordinates of people-oriented, firmly weld the safety awareness in the heart, refine it in the institutional arrangement, and implement it in concrete actions. Only in the face of floods and disasters can we be targeted and leisurely.
