[0002] Channel flow measurement involves the precise measurement of the velocity and flow rate of water within a channel. Accurate flow data facilitates the rational allocation of water resources, flood warnings, and irrigation scheduling. It also helps ensure the safe operation of water conservancy facilities and optimize water resource utilization. Channel flow measurement typically uses a flow meter (such as a Doppler flow meter) to directly measure water velocity and calculate flow rate based on cross-sectional area.
