Abstract

Against the backdrop of global climate change, extreme precipitation events are occurring with increasing frequency, elevating the risks of river floods and urban waterlogging. Traditional water level monitoring methods, which often rely on manual processes and are characterized by significant time lags, are struggling to meet the stringent requirements for timeliness and accuracy in modern flood prevention and disaster reduction efforts. Internet of Things (IoT) technology, as a major breakthrough in information technology, provides the core support for building intelligent, networked, and high-precision modern water level monitoring systems through the integration of sensor technology, wireless communication, and cloud computing. This paper aims to explore the deep application models and significant potential of IoT-driven water level monitoring systems in the field of flood control and disaster reduction. The article first analyzes the principles, advantages, and disadvantages of current mainstream contact and non-contact water level monitoring technologies, such as pressure, ultrasonic, and radar sensors, providing a basis for technical selection in system construction. Furthermore, it systematically elaborates on the layered architecture of an IoT system— “Perception-Network-Platform-Application”—and how it enables closed-loop management of the entire process, including real-time data collection, intelligent warning triggering, flood model coupling, and emergency decision support. Research indicates that this application model can significantly enhance the foresight and scientific basis of flood forecasting and warning, provide critical data support for disaster response decision-making, and win valuable time for public evacuation, ultimately effectively mitigating the loss of life and property caused by flood disasters. It holds substantial practical significance for promoting the construction of “Smart Water Resources” and enhancing public safety governance capabilities.
