  CCTV News: The most common and typical disasters in the flood season include floods, torrents, debris flows, and landslides. How to recognize these dangerous disasters? How do we avoid and save ourselves when we meet?

  Flooding is a phenomenon in which the flow of rivers and lakes increases sharply in a relatively short period of time, and the water level rises significantly. The flood has great natural destructive power, flooding the floodplain and overflowing the embankments on both banks. According to different causes and geographical locations, floods are often divided into storm floods, snowmelt floods, icy floods, mountain floods, and dam-break floods. Tsunami storm surges can also cause flood disasters. A flood process generally has three stages of ups and downs, the appearance of flood peaks and leveling. Mountain rivers have steep slopes, large flow speeds, and rapid flood fluctuations; plain rivers have slow slopes, small flow speeds, and relatively slow fluctuations; Large, with many tributaries, floods often have multiple peaks, and solitary rains often have single peaks. Threatened by flooding, if there is enough time, it should be organized to shift to hillsides, highlands, etc. according to the route; when surrounded by flooding, boats, wooden rows, door panels, wooden beds, etc. should be used for water transfer as much as possible; When it is almost too late to transfer, we must immediately climb on the roof, high-rise buildings, big trees, high walls to temporarily avoid danger and wait for rescue. Don't swim swimming alone, and find that the high-voltage wire tower dumps the wire and the wire is drooping or broken. Keep it away from danger. Do not touch or approach it to prevent electric shock.

  According to past experience, before the flood comes, the relevant departments can achieve timely and decisive forecasting and early warning, the “last mile” of early warning and timely and decisive transfer of personnel can achieve positive effects of disaster prevention and mitigation to a certain extent, and The evacuation of all organizations requires the cooperation of the masses. In areas with high risk of heavy rains and floods, we must do a good job of forecasting and pre-warning before floods occur. The masses must evacuate in time. After the floods, we must do a good job of sanitation and epidemic prevention to avoid the occurrence of infectious diseases.
