Flood prevention measures:
1. Strengthen river management: poor rivers are one of the main causes of flood disasters. Therefore, it is very important to strengthen the management and maintenance of river courses. Measures such as deepening and widening the river course, dredging the river bed and cleaning the river course can be taken to improve the diversion capacity of water flow and reduce the inertial resistance of the river course, thus slowing down the flood development and eliminating hidden dangers as soon as possible.
2. Establishment of flood control dispatching system: The establishment of flood control dispatching system can effectively prevent the occurrence of flood disasters. Through the scientific analysis and prediction of meteorological and hydrological information, a reasonable flood control scheme is formulated, the reservoir water level and river water level are adjusted in time, the flow is controlled, the safety of people's lives and property is guaranteed, and the impact of flood disasters is alleviated.
