[0002] As the global climate warms, extreme weather events occur frequently. Floods are one of the most common and destructive natural disasters. Flood disasters occur from time to time, posing a serious threat to people's lives and property. Therefore, it is crucial to establish an effective flood warning system. Flood warnings can detect signs of floods in advance and warn relevant departments and residents in time, giving them enough time to take emergency measures to reduce disaster losses and casualties. It is of great significance to organize evacuation and flood relief work in a timely and effective manner. Therefore, flood warning work is urgent, and the research and development of flood warning devices has become a top priority.
