Autumn flood refers to the phenomenon that rivers flood in autumn from beginning of autumn to the first frost due to the continuous autumn rain.
The flood peak discharge in autumn flood season is generally not as large as that in summer flood season, but sometimes the total amount of secondary flood is large and lasts for a long time, and the river embankment is submerged for a long time, which is prone to danger and poses a great threat to the embankment. Summer flood season and autumn flood season are connected, both of which are main flood season, also called summer flood season.
Causes of autumn floods
The weather is extremely abnormal, with frequent local rainstorms. If the rivers and their tributaries in a certain area rise at the same time, there will be a big flood, which is also rare in history and one of the reasons for the serious autumn flood.
Key points of autumn flood prevention and control
1, be sure to stick to your post, strictly observe the discipline of disaster prevention, strengthen the implementation of the system of 24-hour duty, leadership shift, information submission, etc., to prevent responsibility and work from not being in place.
2. Adhere to "flood season, investigation and rectification", strictly follow the requirements of "three investigations", continue to carry out all-round investigation in the whole flood season, and control the risk of geological disasters from the source. Especially for densely populated areas such as counties, towns and villages, construction sites under construction, near schools, and along traffic trunk lines, preventive measures are implemented.
3. Strictly follow the rigid requirements of "Three Avoidances" and "Three Emergency Evacuations", resolutely and actively transfer threatened personnel in advance, and do a good job in resettlement and control of the transferred people. It is forbidden to return without authorization before the danger is lifted. Assign a special person to handle the early warning information of monitoring equipment in time and transmit it to the person in charge of disaster prevention and the monitor in the first time, so as to maximize the advantages of "civil air defense+technical defense" and win valuable time for emergency avoidance.
4. According to the requirement that "the management industry must manage the ground disasters", supervise and guide the project owners and construction units under construction to earnestly fulfill their disaster prevention responsibilities and implement various preventive measures; Especially before the arrival of heavy rainfall or when disaster signs are found, the construction unit should take decisive measures to evacuate people in the dangerous area in advance.
5, strictly implement the information submitted, all kinds of geological disaster early warning information to the first time to reach the county, township, village, group, household, point, to avoid risks to the maximum extent. It is necessary to report sudden geological disasters (hidden dangers) in a timely, accurate and standardized manner, so that the initial report is fast, the continuation report is accurate and the final report is complete, and the video, photos and data are true and reliable.
