The present invention provides a stream flowrate calculation method comprising the steps of: (a) inputting, to a measurement database unit (110), section measurement data and stream width measurement data for a predetermined stream section (S100); (b) allowing a water level determination module (120) to determine first water level data for the predetermined stream section by substituting assumed first flowrate data for a preset equation (S120); (c) allowing a stream width calculation module (130) to determine first stream width data by the section measurement data and the first water level data (S130); (d) allowing a repetitive calculation module (140) to repeat steps (b) and (c) by substituting second flowrate data for the preset equation, wherein N^th stream width data and N^th flowrate data are matched; and (e) allowing a flowrate determination module (150) to determine, as a final flowrate value for the predetermined stream section, the L^th flowrate data matched with the L^th stream width data that is a value closest to the stream width measurement data among the first to N^th stream width data matched in step (d) (S150). Therefore, the stream flowrate calculation method can increase user reliability.
