Provincial Hydrological Water Resources Center Harbin Branch notification:

1. The upstream water situation. At present, the tender river is stable, and the water volume of the second Songhua River and the Lalin River is large. The water level of the Nenjiangjiang Bridge Station is 136.66 meters, a fall of 0.04 meters from the previous day, and a 990 cubic meter per second of the alert water level. Mi, the flow of 980 cubic meters per second; the water level of the second Songhuajiang Fuyu Station was 132.89 meters, an increase of 0.18 meters from the previous day, which was 0.67 meters below the alert water level, and the flow was 2,2120 cubic meters per second. The rice increases by 0.34 meters from the previous day, which is 1.31 meters below the alert water level, and the flow is 760 cubic meters per second.

2. River water level. Affected by the upstream water, the water level of the Songhua River showed a trend, and the other river water levels generally declined, lower than the alarm water level 0.65 to 4.05 meters. Compared with the water level in the same period over the years, the dry flow of Songhua River is 0.39 to 1.82 meters high; the Lalin River, the Niu Niu River, the Chonghe, the Daisi River, the Ash River, the Hulan River, the Ant River, the Huangni River, and the east bright The Pearl River, Northwest River, and Mudan River are 0.03 to 1.82 meters high; the upstream of the Ant River, the forar, and the Balan River are low 0.05 to 0.40 meters.

3. Reservoir water storage. The water level of the upstream Nenjiang Nilki Reservoir was 206.61 meters, which was lower than the flood limit of 6.76 meters, the water storage capacity was 2.70 billion cubic meters, accounting for 31.4%of the total library capacity, 463 cubic meters per second, and the outlet flow was 307 cubic meters per second; The water level of the second Songhua River was 256.36 meters, which was lower than the flood limit of 4.14 meters, the water storage capacity was 5.578 billion cubic meters, accounting for 53.8%of the total storage capacity, 1881 cubic meters per second, and 885 cubic meters per second.

The 253 reservoirs in the city are running below the flood limit. The water level of Mushan Reservoir is 316.6 meters, which is lower than the flood limit of 0.4 meters, and the water storage capacity is 316 million cubic meters, accounting for 60.4%of the total storage capacity, 113 cubic meters per second, and the outlet flow of 85.2 cubic meters/second; Xiquan Eye Reservoir Reservoir The water level is 208.57 meters, which is lower than the flood limit of 0.43 meters, and the water storage capacity is 241 million cubic meters, accounting for 50.4%of the total library capacity, 24.1 cubic meters per second, and 40 cubic meters per second of the outlet; It is lower than the flood limit of 0.46 meters, the water storage capacity is 91 million cubic meters, accounting for 32.9%of the total library capacity, 141 cubic meters per second in the storage, and 255 cubic meters per second. The Dadingzishan Aviation Hub is managed as a large reservoir, but there is no flood prevention task.

Combined with the analysis of the meteorological and hydrological department, the conclusions will be concluded as follows:

1. Rain love analysis. Affected by the interaction of Western wind grooves and weakened typhoon circulation, there will be obvious rainfall weather in our city recently, and the main rainfall period will be from 6th to 7th during the day. It is expected that the process rainfall is expected to rain in the main urban area, Wuchang, Shuangcheng, Acheng, Hulan, Bayan, and Binxian County. ), Other districts, counties (cities) are small to Zhongyu (5-20 mm), and the smallest rain is 40-50 mm. The rainfall is also accompanied by strong convection weather such as short -term precipitation, thunderstorms, and hail, and the maximum gust of gust is 7-8.

2. Recent water information analysis. Affected by the upstream water, the water volume of the Songhua River in Harbin above Harbin in the next 7 days has increased. The water content of the Lalin River Basin is close to saturation. Although the dry tributary is in the deing period, the water level is high. If a strong precipitation occurs, the flood may occur. Individual rivers or river sections may be over -alarm.

3. Related suggestions for flood prevention. The first is flood disasters. This round of rainfall is concentrated in the central and western parts of our city. The risk of geological disasters such as floods and mudslides in mountainous and half -mountain areas increases, which may cause flood disasters in small and medium rivers, reservoirs, and Tangba. Relevant departments need to pay attention to preventive measures. The second is the strong convection weather. The rainfall is accompanied by strong streaming weather such as heavy precipitation, thunderstorms, and hail at the same time. Relevant departments need to pay attention to preventing urban and rural waterlogging, tunnel culverts, waterlogging and waterlogging, strengthen drainage of urban low -lying roads, do a good job of urban safety and farmland. manage. Third, small and medium rivers have skyrocketed. Focus on the small and medium -sized rivers due to the heavy rainfall, especially the Shaoling River and the dry tributary of the Shaketu River rose significantly. Relevant departments, districts, counties (cities) should take precautionary measures and transfer of personnel in advance.

In response to the discussion, the meeting made the following requirements:

First, we must implement the responsibility for flood prevention. Strictly implement the "rain love flood situation is the order, the front line is the position", and all kinds of responsible persons at all levels are in place in advance. , Precise goals, precise measures, find problems, study countermeasures, and make every effort to prevent heavy rainfall prevention. Second, we must strengthen rivers defense. It is necessary to strengthen the flood defense of small and medium -sized rivers, implement the flood defense measures one by one, encrypted the frequency of investigation of the embankment, and prepare sufficient soil materials in weak parts such as insurance work insurance segments, disease insurance gates, etc. Essence In particular, we must do a good job of embankment -free protection, and the people with the characteristics of rising and steep characteristics of rivers affect the transfer and resettlement work to ensure the safety of the people's lives.

Third, we must strengthen reservoir scheduling. Strict implementation of the reservoir during the flood season scheduling plan, it is strictly forbidden to operate the water level without the flood limit without authorization. It is necessary to strengthen the federation of the federation of the meteorological and hydrological department and the information sharing of information, make full use of the prediction of the flood control tasks, flood discharge methods, and engineering conditions of the reservoir in combination with the references of the reservoir. The results of leakage analysis, pre -leaking the library in advance, and giving full play to the ability to regulate the reservoir and the benefits of flood prevention.

Fourth, we must do a good job of mandarin defense. It is necessary to rely on the mountain flood disaster monitoring and early warning system to establish a digital and information -based means of calling mechanism, closely monitor the upstream and downstream of the area and related watersheds, changes in the left and right shores, and change the process, speed up the release and spread of early warning information, and strive to strive In the shortest time, the person responsible should be applied to the person who decisively organizes the risk to avoid risk, so that the early withdrawal should be withdrawn, the withdrawal must be withdrawn, and the withdrawal should be withdrawn to ensure the safety of the personnel in the dangerous area.

Fifth, we must improve emergency capabilities. Further build a professional force for anti -flood rescue, improve the work plan, implement the measures to respond to action, strengthen emergency drills, command scheduling, strengthen risk research and preparation, and timely supplement equipment and equipment and disaster relief materials. state. Strengthening the waterlogging in urban waterlogging, low -lying areas, and underground spaces must be arranged to be on duty, ensuring safety by accelerating drainage and organizing transportation bypassing, and ensuring normal cities' normal operation.

Sixth, we must strictly duty. Discipline seriously, strictly implement leadership leadership and 24 -hour duty system. Strictly focus on key parts such as reservoirs, rivers, floods, and low -lying waterlogging points, increase information submission, and report the situation of rain, water conditions, flood conditions, disaster conditions and measures in a timely manner. If it fails to cause serious consequences, serious accountability in accordance with regulations.
