Hydrologic monitoring factors include water level, flow rate, rainfall (snow), evaporation, silt, ice and the like, wherein flow rate measurement is particularly important. During the flood peak period, the river flow rate is usually expressed as several times of the normal state, the real-time flow rate monitoring can play a role of early warning, and the flow rate is one of important hydraulic factors of a water environment and a water area ecosystem and is a key factor influencing the diffusion of pollutants and the migration and precipitation of sediments. In addition, the flow rate is a key water flow signal for survival and propagation of fishes, and behaviors such as migration, spawning, foraging and the like of the fishes are influenced by the flow rate.
